u sound like BdubO

[allendupras]

I have 39 apples and counting!!!

[Frogfish999]

lol, it IS the best Channel ever :D

[anonymousb37]

I would love to create Minecraft griefing tools.

[dragonthewatcher]

OMFG I HATE SHOCKWAVE ITS SO SLOW

[kidharris55]

im here cuz this is what i wanna do. i wanna make video games n runescape bots. (:

[Nethertar]

Completely agree with you Bucky

This is the best channel on YouTube (Y)

[rookie144]

also how did you learn java?

[rookie144]

Hey bucky do you have any ideas on how i'm going to remember all this are there ant tricks i follow along in the videos and everything but i feel like if I go and try to do some thing my self I wont be able to do jack :(

[Seracinfinity]

@rookie144 Just repeat it, and try and create your own programs.

[TheMathMystic]

Yo dawg I heard you like constructors...

[MrYouMath]

Bucky nice cliffhanger!

[RaptoJP]

JUST ONE MORE TUTORIAL

[pacinotube]

Good job guy!

[C0GSniper]

I may play Minecraft but I'm here to learn for Android =]

[HardlyMinecraft]

out of interest, if he justs set minute, not hour or second, what heppens? and if it throws an error or some problem, do you make another constructer with 0,m,0 ect until u have done all possable ways so it will be always correct?? PLEASE ANSWER!

[35spike2]

wow... he is right... this is confusing :/

ur other tutorials better clear stuff up!

don't let me down now bucky :)

[0FunkyMonk0]

here is the link where he teaches you how to build constructers, it may be usefull :)

[agcummings11]

lol 7,000 people gave up.

[tehB3NJ1E]

Following This + Listening to deadmau5 on 25% Volume = WIN!

[Kevingston96]

Thums up if you wanted to learn java to mod minecraft!

[xJustas]

@Kevingston96 Victim of likes.

[zVenFTW]

somehow the way he declare variables piss me off.... I mean, instead of a line for each declaration, he can just use one... "private int hour, minute, second;" :/

But well, maybe is better for him.

[Wilzork]

The viewers are smilling...

[conquerGALVIN]

so much more useful then my lectures at uni :D Im going to learn C++ and HTML5 from you as well :P

[CodeSensitive]

Everyone is like saying they watch 3 a week!... i watch 20 a day(i spend alot of time tho becuase i still studie them)

[CrisIsRatedX]

@CodeSensitive same here :D

[MeahVonB]

it is the best channel ever :D

[idiotrun1997]

So why don't you want any other class to access variables hour minute and second? It won't make a difference in the final program.

[Blizeful]

I dont understand why we needed the first three constructors... Couldn't we have just stick the last constructor since it had all 3 variables for the arguments

[TheGrobar1000]

lol i use 2 youtube tabs...one for this tutorial and another one for 17th tut reminding me what constructor is .

[thecoop022]

What's with the minecraft people.... I'm gonna make my own First Person Shooter from scratch.

[AndreiDumy]

you lost me..

[etizzei1]

my eclipse doesnt have the console :(

[manasume]

3 thank you's in 1 video

[1SavageDragon1]

o.o....minecraft!

[jigoge]

SOO MANY TUTORIALS!!!!

[codycero1]

this is gonna take an hour?!?!?!?

[V1d4R]

I don't know if you mention this in a part later on, but it doesn't look just for a constructor with 2 or 3 parameters, it also looks on the type of parameters. For example you can have a constructor with one float variable as a paremeter and also a constructor with one int variable.

So it's only forbidden to have the exact same header with the same variable types.

[TheDrCN]

Whenever I watch one of his tutorials, I always spend some time improving on his program. Then when I move on to the next tutorial, I just can't bring myself to delete all of my work.

[SurgeDungeon]

@TheDrCN Do what I do and make the class as "Lesson39apples" and "Lesson39tuna", then you can save your work and have a source to look back on if you forget too!

[VaginosaurusRex]

am i the only person who plays minecraft and is learning java just for future use with no intentions of modding minecraft? O_O

[xero907]

@VaginosaurusRex yep

[itsjustthecause]

@VaginosaurusRex no same here

[MinecraftCreators]

@VaginosaurusRex Ofc not...

[hmongmiami]

@VaginosaurusRex no

[MattMcCool]

@VaginosaurusRex I'm a Minecraft player, and i intend to eventually make my own games when i'm done with these!

[bace1000]

@VaginosaurusRex Nope, you're not alone :D

[xXBlueMonkeyHDXx]

@VaginosaurusRex nope

[fgf80]

@VaginosaurusRex I am going to be taking a Java class from a textbook, and I've never liked Java textbooks I've seen, so I'm just learning it ahead of time..... However..... -.-..... now that you mention it.... MINECRAFT MODS

[ZeBeaupre]

@VaginosaurusRex I don't even play minecraft

[cocksnap123]

@VaginosaurusRex Yes.

[HTMLMINECRAFTGUYJAVA]

@VaginosaurusRex I'm learning it for games. ;)

[HappyTissues]

@VaginosaurusRex no

[Espiration]

@VaginosaurusRex I'm play minecraft and I'm going to use this for android app development

[Darkcore71]

@VaginosaurusRex I'm certainly not learning java just for Minecraft.That would be fairly pointless.

[St3althyNinja]

@VaginosaurusRex You are not alone. I am.

[FewCode]

@VaginosaurusRex i was told that i have to learn it for a uni course. so i decided to go ahead.

[Frogfish999]

@VaginosaurusRex yep :D

[NinjaCatStudiosArt]

@VaginosaurusRex I am, but I still want to dabble in Minecraft modding, I want to see how other people's code works, so I can learn a bit off of it and be more experienced.

[amazoneon]

@FateCraft Ahh, k. Thanks for you help!

[amazoneon]

@FateCraft Would you please me able to point out where you went after finishing these tutorials to learn how to to this, as in: what other sources did you use as tutorials?

[RazorSRaider]

@FateCraft how the hell did you make a meteorite mod already???

[michaeldcurry1]

Learning this for two reasons, the first being, I've made a few games in the past, Java is a big step up, games dev is a big part of my life. Second, Minecraft (Y) WOO!

[XXXSenseiZXXX]

yea, im a minecrafter

i learning this to make mods lol

[HenkeFemton]

Any other Minecraft players around?

[JamEngulfer221]

@HenkeFemton MEEEEEEEEEEEEEE I wonder why so may MC players come to Bucky's tutorials?

[LeTrungAnh]

@HenkeFemton I'd like to give you a thumbs up but it looks like you've got 69 thumbs up. Perfect.

[Aaronster8]

he needs to say at the end "bucky out"

[Aaronster8]

java would be hell without eclipse

[MusicRevelance]

bucky, the ideal teacher.

[JPxKillz]

Chyuh thumbs up if your 12 to 15! Whoohoo, ha. im 14,

[xVerbati]

@JPxKillz Since i'm 18 i had to thumbs down.

[jessenetwork1]

im -10000000000000000

[Blackllama13]

I'm 14, been playing around with different coding languages since I was 12. Started with lua in a game called roblox, then experimented with c++ for a while, I don't remember too much now, and I know html and some css as well. I really like java though. it's fantastic!

[leadpx]

@Blackllama13 html and css are not programming languages, but markup languages. I admire you for start learning programming so soon, congratulations! :D. I'm 19 and I started with PHP at age 16 I guess. Then I moved to C, C++, some javascript, now Java.

[samusrules93]

OHH now I get it This was the first tutorial that was really confusing me. I went back and re-watched # 17 (constructors) which helped, but when he quickly said that 'this just invokes this same constructor again, just with different arguments' is when it clicked for me. Thanks Bucky!

[GMonkeyHD]

Im 8 month's old.

[doody884]

im 15:D

[iambobby100]

13



[TwizzyTheWizzy]

methods in java == functions in PHP

[dtgonzalez1]

Im not sure which is more confusing arrays or multiple constructors :( hopefully ill understand in the next tutorial

[mkicvr]

private int hours, minutes, seconds; would be a lot more efficient. Great tutorials though, Bucky!

[trancluong]

These lessons are goods thanks for post online.

I learned c.c++ and java for along time. but never use them.

These tutor help me to refresh and also learn alot of new lessons from you.

Again Thanks you bucky so much.....good job

[qbblast]

I'm 12, and I understand this, I'm having fun learning to different ways to write in the java script language and has always wanted to created my own game from scratch...

"I'm (age), and I (personal stuff that probably no one wants to actually know, or care about)."

[TheStuartWallace]

hehe, Public tuna, Private tuna :3

[zerohourkevin]

I'm a certain age and I happened to be learning Java from the best teacher EVAR. w00t

[Misteryman94]

lol I just turned 17 and learning my first programming language... I guess I'm kinda late seeing that everyone else is 4 years younger than me

[vgdkhs]

@Misteryman94 You are reading my mind ;)

[xu3369]

im 12 yrs old and what is this

[KlauerJ]

so when you type this(0,0,0) it means just enter that into the final tuna(int h, int m, int s)?

[lilwarthog]

@KlauerJ it is like doing this tuna(0,0,0); So yes pretty much.

[FreePKMNWalkthroughs]

omg eclipse started working! NOW!!!!! i mean wtf? lol

[ZiX3NeMa]

Im a 78 year old teenager and want to be a programmer as an adult!

[Flow0Toe]

@ZiX3NeMa right.

[Babelfish112]

these tutorials are better than my whole Uni IT course!

[threeclock]

Can I do public void tuna() ? or public int tuna() ?

[c0decub]

I'm a 40 year old boy and I want to be a professional computer scientist when I grow up!

[ampersandals]

fixed it

[ampersandals]

my code is almost identical other then class names but im getting heaps of error messages telling me that the constructer is not defined

[BladedTimes]

Thanks Bucky for all these. Learning my6th language ;)

Oh but not speaking languages. Computer Program languages.

I know VB, Javascript, HTML, CSS, and Flash. Thanks to this I am getting Java. :D

[Flow0Toe]

@BladedTimes Haha wannabe scriptkiddie? U know flash programming language? It's called Actionscript lol

[BladedTimes]

@Flow0Toe 1. No not wannabe scriptkiddie, just a show-off programmer, I am kindof a dickhead about it sometimes, but I am getting into programming for real, it's my planned career, I've already got a job open for it, when I get through at least a year of college, so no. NOT wannabe (: 2. I know it's called actionscript but I don't like calling it that it looks weird to me, like how I spell the word 'creep' creap, because 'creep' looks weird to me, so you had a completely wrong first impression.

[Flow0Toe]

@BladedTimes If you're "serious" about becoming a programmer, please learn what the difference of scripting languages (HTML/Javascript) and programming languages (VB) are..

Cause u sound kinda stupid right now.

[Flow0Toe]

@Flow0Toe My fault, HTML is not a scripting language but a markup language

[BladedTimes]

@Flow0Toe Ah, well I didn't think about that difference, hm.. S:

[tedtdu]

I am 41, hopping to be a programmer in future

[walkerneo]

@tedtdu You shouldn't be hopping at your age.

[xXxDiukexXx]

@walkerneo lol ur meanie :P

[De4sher]

dude, these tutorials are so great, i'd let you have me!

"Look through this one, see where thrsh shre argumnts

Look through this one, see whre theresh shre argurmunts"

[d3fish3r3]

Has anyone else noticed that with each part of the tutorial the amount of views get lower and lower? If each view is a person that looked up a Java tutorial hoping to learn Java, then 600k people have given up since part 1... XD

[cACTIfARM]

@d3fish3r3 Holy shit, that is kinda mind-blowing. And i also think we should note that for the rest of the tutorials, the views stays at about 50k, which means that all the people at this tutorial now, has the mind to go trough the whole series too.

[kehayov89]

@d3fish3r3 Probably they found a job and don't need more tutorials :D

[TheKyshu]

@d3fish3r3 As of now 930.000 xD (And I know, where all these "newbies" (sorry :>) came from *cough* minecraft *cough* Well, I came here specifically for Java and Minecraft, but I also had a lot of general programming experience before (C++, Basic, ...) :P

[TacticalKillClan]

After I watched you series of Java I wanted some tuna.

[Daedalus733]

You sorta went crazy with the methods in this one.

[skate2late]

Anyone here play Gmod and by any chance have mastered lua scripting if so how do you transfer variables across scripts im makking a gamemode and i need to put i variable from init into cl_init

[H2kPrograming]

AMAZING tutorials man, ive learned soo much. Cant wait to start making GUI's

[legoisfun]

Guys, I know it's a lot of fun flying through these tutorials, but I seriously suggest trying writing some more complex programs. You're gonna be needing to combine a lot of your knowledge in complex programs, so it takes time and practice. Even if you completely understand these, you will need to try this. They teach all this in high school and college for over a semester, so I would be surprised if you can do the same in a week. Good luck :)

[deadbe4uknow]

@legoisfun

I realise this. But i have no idea what programs to write to practice everything i've learned.

I think it would be great if bucky put some exercises online. (like make a program that can do this, that and that. ) And puts the sollutions online. Thàt is wat would make these tutorials complete.

[TheMacManPro]

@deadbe4uknow SO TRUE!!!! I almost forget it, and excercises would be great, and of course if one is not able to complete it, the solution too. BUCKY PLEASE!!!

[cpgamer368]

this is my 4th day of java! and ive learned so much!

[mrgnippy]

Ok, in what tutorial did he say what this is "this(h,m,0)" i know he said what this is "this.h" im so confused what this means "this(h,m,0)" means... HELP IM SO CONFUSED!!!

[johnxxx9]

@mrgnippy this(h,m,0) means that tuna constructor which has 3 arguments. What we are doing in "this(h,m,0)" is if u enter only 2 input instead of 3 fields for hour, minute and second, then we consider the 3rd input to be 0, this converts 2 arguments(h,m) to 3 arguments(h,m,0). This 3 arguments we send it to the "tuna" method which takes 3 arguments (ie 4th tuna method). The 3 arguments are necessary to continue that's why whatver the no of arguments we make it to 3 and then send it.

[xXChaosHavokXx]

i r 14

[Jesteria78]

nice, but I am glad he never forgets the "L" in pubLic... ;-0

[DanielsVision]

bucky, dude, you can never spell "public"...you should work on that :)

love your videos!!!

[Mr13p]

Wow I thought 15 was young to learn java. I guess not.

[TheGreekSkater]

@Mr13p i'm 14

[zzzROSSzzz]

@superflyj416: good one lol

[bowlofnoodl3]

What is all this about and I am 25?

[SparxI0]

crickets in the background :D

[Jozekban]

i wanna ban bill gates on redtube, help me

[mingming2006]

"Best Channel ever" yup you sure got that spot on Bucky.

[jaripeck]

When an instance of a class is created using new it has to be initialised. To initialise an object you need to initialise its instance variables. This is done by a constructor.

[Empeizan]

I'm 13 and I know basic, java, c++, and assembly.

[TheJavabat]

u r awesome!!!!!!!!!!!!!!!!!!

[Gilster85]

YOU ARE AWESOME!!!!!!!!!!

[rashkeed]

Bucky i hope ur finances are good, else we can all contribute something to u

[omgmonkeybanana]

omg i listened to Daft Punk while watching this vid, and it was sssooo AWESOME!!!

[banebajonet]

this refers to class fields , not method fields.

important is that you showed how it works.

good job bucky !

[ganonlight]

Yes, it is the best channel ever :D

[MrOprea3]

Bucky , i wanna start buy saying Thank you !!for all of your wanderfull tutorials thow is a good bussines behind it ,,,, not as good as filming cats and booty dancing(shiit) I am studiig Java now and i am folowing your tutorials as well . I just wanna say that you can make the constructor much easy just presing Alt+insert on Netbeans and you got it in the Eclipse menu as well , becouse the red dots really confuse the begginers like me or others . Anyway you are my best youtube bud

[superflyj416]

I'm a 25 year old boy and I want to be a computer programmer when I grow up!

[kumaramitme]

@superflyj416

u will surely become an computer programmer before turn 50

[blingkid00]

@superflyj416 lmao



[Video4Winter]

@superflyj416 and im 12 so? anyone can be a programmer (i know html, php and now im learning c++ and java)

[SparxI0]

@Video4Winter you don't get the joke -.-

[zilvwang]

lol arent u a man not a boy?

[cACTIfARM]

@superflyj416 uhhhh, do you mean 15 yo?

[LyriiczBoii]

@cACTIfARM I think he's joking ;)

[cACTIfARM]

@LyriiczBoii Yh, might be :)

[hotketchup99]

@superflyj416 im 12 :D

no joke!

[Taurusaud]

Now something I don't understand - using your code, let's say I call the first constructor, and it of course calls the fourth constructor with the three arguments...

Now are two objects being created in memory i.e. an object from the first constructor, and then an object from the fourth constructor?? OR... is the object from the first constructor being created and then that spot in memory is being overwritten by an object created from the fourth... OR does the compiler never create the first?

[RsKaa111]

Omg! Love your vids man! I love 'em! Keep it up!

[jackdecemberdk]

Thanks a lot for making great tutorial, the best java tutorial that I have ever seen. you are imba!! Bucky
