Please ignore my poor formatting and my bad way of doing things. At the time of writing I have about an hours experience with java, and I am a tad stuck with this code I have written.


class maths
{
public static void main (String args[])
{
int x;
x = Integer.parseInt(args[0]) ;
int y;
y = Integer.parseInt(args[2]) ;
System.out.println (x*y) ;
String f;
f = (args[1]);
if (f == "x")
System.out.println (x*y);
else
System.out.println ("Sorry, I only do multiplication");
}
}


OK, the idea is I enter in the command line
java maths 3 x 4
and it returns
12 (as a test, to make sure that my casting and maths were right)
12 (because I have an "x" as args[1])

Or I enter
java maths 3 / 4
and it returns
12 (as the test)
Sorry, I only do multiplication

What happens is that it compiles perfectly, then:

% java maths 3 x 3
9
Sorry, I only do multiplication

% java maths 3 / 3
9
Sorry, I only do multiplication

I am at a loss.

Also, is there a better way of taking a string from args and turning it into an int?

Thanks all.
