[andres123587]

what are the differences between action performance and mouse clicked?

[djjagen]

thanks for your video

[sikanderzeb]

awesome!!!



[EldaMagalys]

the code is the next people... dont be so....

plusminus = Double.parseDouble(String.valu­eOf(display.getText()));

but in display.getText() you must use the name of your jTextField...

[Theonlyoneleft1000]

plusminus=(Double.praseDouble(­Sring.value01(dis)))

What is after that?

[herraph1]

dont know but instead of display, cant we use SOUT*Tab*??

[herraph1]

display.setText my netbeans cant recognise it. Help PLZZZ and also display.gettext

[vishal7589]

@herraph1 same problem with me...

[FernandoPST]

@vishal7589 you gotta put your variable name before the .getText, for example if your text field is called myTextField, the line would be: myTextField.setText();

[herraph1]

display.setText my netbeans cant recognise it. Help PLZZZ

[miltoskat2]

are you idiot? we cant see the plusminus code cant you move the camera idiot???

[chrissphinx]

@miltoskat2 here you go idiot

plusminus = (Double.parseDouble(String.val­ueOf(display.getText())));

[Raotor123]

you can't just use the name how it is there everything wil be alright

[TheMrDclaws]

Uhm it says Jbutton5Actionperformed instead of jbutton1actionperformed how can i delete the 5 and put into the 1

[TheMrDclaws]

display.setText(display.getTex­­t()+jButton1.getText()); does not work for me help!!

[jsayram]

@TheMrDclaws did you ever get it to work?? what was the problem cause im having the same problem

[shg297]

ok i found the code for the positive and negative sign button here it is  plusminus=(Double.parseDouble(­String.valueOf(display.getText­()))); plusminus=plusminus*(-1); display.setText(String.valueOf­(plusminus));

srry i couldnt put it up when the video was made (i watched this video for the first time now) Hopefully everyone who was looking for the code found my commen :)

[schwamm11]

@MrDewloo you have to write display.setText(display.getTex­t()+jButton1.getText());

[MrDewloo]

this is what i got for 1. why? javax.swing.JButton[,12,56,49x­40,alignmentX=0.0,alignmentY=0­.5,border=javax.swing.plaf.Bor­derUIResource$CompoundBorderUI­Resource@253498,flags=296,maxi­mumSize=,minimumSize=,preferre­dSize=,defaultIcon=,disabledIc­on=,disabledSelectedIcon=,marg­in=javax.swing.plaf.InsetsUIRe­source[top=2,left=14,bottom=2,­right=14],paintBorder=true,pai­ntFocus=true,pressedIcon=,roll­overEnabled=true,rolloverIcon=­,rolloverSelectedIcon=,selecte­dIcon=,text=1,defaultCapable=t­rue]

[ramblabike]

Thanks Bro!

it works.

I delete the minusplus button, because it didn't work

[shail28ch]

thank u for teach me a calculator.

[dsnyder9785]

what code is used in decimalActionPerformed to check the display to see if there is already a decimal in the string, and then prevent a secondary decimal to be placed in the display?

[fatcrewz]

shouldn't plus minus doesnt display as decimal?

[VikingNightmare]

@fatcrewz display.setText("");

this would be it, anyway the one shown in the video.

[MonkeyDPascua]

what is the code for C??

[MonkeyDPascua]

great vid, but button clear doesnt erase. what is the rest of the code?? please, i need it

[jrmn1009]

[samadkhan2007]

Very Helpful. Thanks

[anupamvipul233]

plusminus=(Double.parseDouble(­display.getText()));

try if u r in 6.9.1

[ymerdrengene]

@anupamvipul233 thanks man ;)

[dangeroussak]

THE CORRECT CODE IS --------

plusminus=(Double.parseDouble(­String.valueOf(display.getText­())));

 plusminus=plusminus*(-1); display.setText(String.valueOf­(plusminus));

[tama0031]

why i can't display the buttons but my codding is right is this working with 6.9.1?

[danmacion]

@tama0031 true! im trying it now. i cant get it!? fuck! help me!

[sansha4mail]

Is this done on NetBeans IDE 6.9.1 ? Bacause i'm not getting the popup window when you typed '"display.setText()".

Reply plz!

[franciscounal]

part of the code that is hide is

plusminus=(Double.parseDouble(­String.valueOf(display.getText­())));

plusminus=plusminus*(-1);

display.setText(String.valueOf­(plusminus));

//thank you I like it so much.

[tama0031]

@franciscounal tnxx

[ema97sardo]

display.setText(display.getTex­t()+jButton1.getText());

[AppsForFree]

The full code is :

plusminus=(Double.parseDouble(­String.valueOf(display.getText­()));

plusminus=plusminus*(-1);

display.setText(String.value.O­f(plusminus));

[wilan7]

display.setText(display.getTex­t()+jButton1...

please!!!

[Europemaster]

@wilan7

.getText()

[legionz200]

your video suck i cant see the rest of the code

[hiyazan]

cooool

[FlablessGuy]

What's in the rest of plusminus=(Double.parseDouble(­String.valueOf(display...? Didn't really get to see it.

[etaxalo]

thanks for the solution i will try it

[etaxalo]

i use the 6.5 of netbeans and fron this line

display.setText(display.getTex t()+jButton1.getText());

it doesnt like the "display" word any ideas why?

[julesbond07]

"display" is the name for the text field where things are displayed

[thuzhar]

@etaxalo display if a variable name for the textfield

[goldar15]

how him maked this sentence?

i maked this sentence but i get error with the plusminus because i give String instead give a Double value.... you think a few please and help me, i don't understand.

[lashemaxej]

but what if the decimal button is clicked more than once?

[thuzhar]

@lashemaxej you can just put an message saying "error dumb ass try again"

[EeyoreXD]

At 5:00

plusminus=(Double.parseDouble( String.valueOf(display.getText ())));

You can do this code instead since display's value is already a string

plusminus=(Double.parseDouble(­display.getText()));

String.valueOf only converts any other data type to String so it's kinda redundant that you did "String.valueOf(display.getTex­t())

[nonsilverio]

posneg=(Double.parseDouble(pan­talla.getText())); posneg=posneg*(-1);

This doesn't work for netbeans 6.5.1, could you help me? I want to make the calculator. Even more, this netbeans doesn't allows me to run the proyect if this is not the main proyect. I hope you can help me

[julesbond07]

you can use: "Double.valueOf(pan talla.getText()).doubleValue"

[saddamdon]

thanks

[critenks229]

@EeyoreXD thanks for the help

[jhonjairo6230]

I learned a lot thanks to your video!

[ValXander]

hey!!!..what about the jButton0?..on my java it appears like this.."jButton10"...how can i make it and change it into "0"digits?....

[thuzhar]

@ValXander right click then edit text

[Zakidream]

at 2:15 private void jButton1ActionPerformed(java.a­wt.event.ActionEvent evt) { display.setText(display.getTex­t()+jButton1.getText());  }

[saddamdon]

thanks

[donovanlb]

I can`t see what he wrote at 5:15 in the +/- button

anybody knows?

[nudelmanarie]

thanks very helping

[thuzhar]

@nudelmanarie i think its helpfull

[luengsc]

for those who don't know what the guy types at 2:19, like one said, it is

"display.setText(display.getTe­xt()+jButton1.getText());"

also you can see it at 2:23

[wiremod]

it didnt work for me it said it cant find symbol jbutton1

[wiremod]

nvm i git it to work

[luengsc]

.....are you kidding? the guy did more than 300 lines for a simple calculator and in "pearl" you can do it in less than 10 ... !

[fawzar]

plusminus=(Double.parseDouble(­String.valueOf(display.getText­()))); plusminus=plusminus*(-1);

 display.setText(String.valueOf­(plusminus));

[justen84]

can anyone answer me, in the method of c button when i write display.setText("");

he said cannot find a symble(disply), is it need kind of import ? or what is the problem? thanks.

[Obliviboy12]

[Giallo81]

plusminus= Double.parseDouble(String.valu­eOf

(display.getText()));

[Obliviboy12]
