i know it seems silly, but how do you use tostring()? the way im using it doesnt seem to work. :(

i get some "cannot find symbol" error with tostring()

    private void jButton1MouseClicked(java.awt.event.MouseEvent evt) {
        int in1 = Integer.parseInt(jTextField1.getText());
        int in2 = Integer.parseInt(jTextField2.getText());
        int in3 = in1 + in2;
        jLabel1.setText(tostring(in3));//error here: cannot find symbol tostring
    }

google hasnt helped me =\

That should explain toString for you. Basically, it's what is called when you convert an object to a String, for example when you print it out. System.out.println(object.toString()); should give you the same result as System.out.println(object);.

You probably want to do something like jLabel1.setText(String.valueOf(in3));.

thanks you :)

for some reason i can never find my answers on java.sun, although i know they're there :o

also. its Object.toString();
so like

Object lol = new Object();//I think. I havent used Object like this before o_O (Just setting it up)
lol = 44444;
System.out.println(lol.toString());

I think that works

Let me just state a very, very important characteristic of Java that caused your problem and might cause you more: it is case-sensitive. Therefore, toString is not the same as tostring, nor is Object the same as object. This might be a bit tricky since Pascal is case-insensitive, but all present or major programming languages are case-sensitive so you gotta get that habit going. :)

By the way, you might want to name your variables and methods more properly or that code is going to confuse the hell out of you later on. :P

yea it was different at first when I first started learning java and c++ to have it case-sensitive since pascal's not that way.

He said 'case-insensitive', not case sensitive.

Go read some stuff about OOP. It will help you mucho.
