String to Integer Conversion

[Jas Oberai]

Hey Friends,
Can you just tell me how to change a string like this to an Integer.I know this is really stupid quetion..but any help would be appreciated.

 
String s= "2.00";
int num = Integer.parseInt(s);
out.println("num is:"+num);

String s = "2.00";
 
Integer i = new Integer(s);
 

Check out the 3rd constructor here:

But of course, new Integer("2.00"), just like Integer.parseInt("2.00"), throws an exception, because 2.00 is a double, not an int.

If you have a String which may contain an arbitrary number, I think your best bet would be something like

int num = (int) Double.parseDouble("2.00");
