Why this java code result is 0

Question

int c = (300-315);
float g = c/300;
System.out.println("percentage of salary changes is : " + g);

Answer 1

Both c and 300 are integer, so their quotient is also integer. You may use any of the following ways to convert the quotient into float or double:

1. float g = c/300.0f;
2. double g = c/300.0;
3. double g = (double) c/300;
