java programming

Posted by Zoe on 2001-06-22

Hi, all I am not sure how much of you do Java
programming, please help me if you can. I have this
for my applet for result output.


String num;
	num = text2.getText(); //input field

	  int x;
	   x = num.lastIndexOf('.'); 
	   x = (x >= 0) ? (x) : num.length();
	   int ft = Integer.parseInt(num.substring(0, x));  
//5    

double test;
test = Double.parseDouble(num) - ft;

labelout.setText(Double.toString(test));



This will look ok and compiles ok but the problems
occurs when I enter a value. You see this line:

test = Double.parseDouble(num) - ft;

Does not work at all. Some how this
"Double.parseDouble(num)" courses a problem and result
in no output.



help me,
zoe
p.s. anyone know any good Java IRC chat channel?
