Thread: whats wrong with this code....it says, 'the operator / is undefined for z=1.0-"A" / 2.0

import java.lang.System;
public class Check01D {

public static void main(String[] args) {
// TODO Auto-generated method stub

double z;
z = 1.0 - "A" / 2.0 + 1.0 % 2.0;
double y;
y = 2.0-z*z/2.0;
double x;
x = 1.0-2.0*y/z;

System.out.println("The value of x is:" + x);

}

}

You probably want the int value of a char. Look at your code, what are are you asking the value of?

Chars are only supposed to go in single quotes. Double quotes are for strings.
