Java: An example for unary post / pre decrement (--) operators

Problem : Write a program to show an example for unary post / pre decrement operators.

Solution : 

Class Decrement (Decrement.java)

public class Decrement {
    public static void main(String args[]) {
        int y = 90;

        System.out.println("Decrement Operator");

        // Original Value
        System.out.println("y   = " + y);

        // Post decrement operator
        System.out.println("y-- = " + y--);

        // After post decrement
        System.out.println("y   = " + y);

        // Pre decrement operator
        System.out.println("--y = " + --y);

        // After pre decrement
        System.out.println("y   = " + y);
    }
}

Here is the output: -

Decrement Operator

y   = 90

y-- = 90

y   = 89

--y = 88

y   = 88
