Double operators

[Homer_simpson]

is there a way to add and subtract doubles?

double IS a kind of variable right? I dunno, cause thats the only way I've seen it. So, I hope Im not making a fool of myself here, but don't you just use JOptionPane.showInputDialog, take strings, put them in variables, then use Double.parseDouble, and put them strings into new variables, and subtract them? or add them? I dunno... if you wanted to user input the doubles, you could use it.

code:

import java.lang.*; import java.io.*; class TestDoubleOps {    public static void main(String[] args)    {       double d = 7.2;       d = d - 2.5;       d = d + 3.4;    } }
