Math Operators- Increment and Decrement

Increment/Decrement operators are used to increase a decrease the value, well the catch is, is it post or pre increment.
++i is different from i++ and similarly --i is different from i--
lets watch this with an example

package Example1;

public class IncrementOrDecrement {

 public static void main(String[] args) {
  // TODO Auto-generated method stub
  int x=10;
  System.out.println(x++);first display x value and then increment so now x is 11
  System.out.println(++x);first it increments which would be 12 and then display
 }

}

output:
10
12

package Example1;

public class IncrementOrDecrement {

 public static void main(String[] args) {
  // TODO Auto-generated method stub
  int x=10;
  System.out.println(x--);first display x value and then decrement so now x is 9
  System.out.println(--x);first it decrements which would be 8 and then display
 }

}

output:
10
8
