Sample for Prefix vs Postfix Increment Operator

//RUN THIS CODE to help you understand the difference between the prefix and postfix increment operator

public class PrePostDemo

{

public static void main(String[] args)

{

int i = 3;

i++;

System.out.println(i); //prints out 4

++i;

System.out.println(); //prints out 5

System.out.println(++i); //prints out 6 -- increments then prints

System.out.println(i++); //prints out 6 -- prints then increments

System.out.println(i); //prints out 7 because previous line incremented i

}
