[surfingtube]

sound is a bit low

[savanath]

hv anyone told u that u sound like nicholas cage

[GWShane]

@savanath Haha nope, haven't heard that one! lol

[DemonXY2J]

Whats the difference between java and comal programming? We use comal instead of java in school

[GWShane]

@DemonXY2J Comal is an older language based on BASIC and pascal. Java is a more modern language based on C/C++.

can you populate an array for example, an array "c" using a fomula?

-2710.0 + 6359.65 * i - 5231.3167 * Math.pow(i,2) + 2063.1875 * Math.pow(i,3) - 421.9375 * Math.pow(i,4) + 43.1625 * Math.pow(i,5) - 1.7458333 * Math.pow(i,6) + 0.5

[GWShane]

@kulangotses I don't see why not. You can populate arrays in a variety of different ways. What I showed was just one basic way of doing it.

[fastbracelet]

thanks body, that was an awesome explanation

[GWShane]

@fastbracelet No problem and thank you!

[Ultimaxkeyblade]

are you using a netbook lolll

[GWShane]

@Ultimaxkeyblade Close enough.. it was a crappy laptop. I'm using something much better now though.

MyArray (12)

MyArray (int 5)

MyArray (Object[] a)-- this could really be anything.

[NajanJan]

thanks for the tutorial :)

I have a question. if we're making array of objects and we want to have 3 constructors let's call it, what would we put in each constructor?

MyArray ()

MyArray (int initCapacity)

MyArray (Object[] a)

[GWShane]

@NajanJan No problem! What danielgirotto put would work.

[matthew360x]

Your helped me soooooo friken mutch thank you!

[GWShane]

@matthew360x No prob man!

[Feuyaer]

omg I have a Java quiz in two days and arrays still boggled me, this helped so much, thanks

[GWShane]

@Feuyaer Great! Glad it helped.

[CaedmonGames]

Partly good. I think you should have done this instead of print vartype[indexnum]

for(int i; i<5; i++)

{

print(array);

}

idk. but i give you 5 stars since it was professional and well explained.

[danielgirotto]

for(int i; i<5; i++)

{

print(array[i]);

}

need to print it at array[index], if you use i you make it array[i]

[GWShane]

@danielgirotto True that.

[GWShane]

@CaedmonGames Yes, that would've been much easier. However, the reason I decided not to go with a loop was because at the time I hadn't yet created a video explaining looping. But yeah, otherwise I would have done something like that. Thanks! I appreciate it.

[nickgila]

thanks for the java programming video btw hw do you memorize all the method??

[devilskullsixtysix]

practice lol.

[GWShane]

@devilskullsixtysix Yep, and lots of it.

[GWShane]

@nickgila I only have some of them memorized. I would think that it'd take a long time to memorize every single one.
