public class FixIt {

public static void main(String[] args) {

int a = 1;

int b = 2;

System.out.println(a / b);

}

}

However, it prints:

0

The reason is because when both operands are integer, Java performs an integer division. To force Java to perform a floating point division, we cast one operand with double.

public class FixIt {

public static void main(String[] args) {

int a = 1;

int b = 2;

System.out.println((double) a / b);

}

}

The result is:

0.5

Fix It

The following program should print the result of 123 plus 12.
