      // 23 gets printed and increment to 24
      System.out.println("Java post-increment = " + a++);
      // a value was 24, incremented to 25
      System.out.println("Java pre-increment = " + ++a);
   }
}

      // 23 gets printed and decremented to 22
      System.out.println("Java post-decrement = " + a--);
      System.out.println("a = " + a);
      // a value was 22, decremented to 21
      System.out.println("Java pre-decrement = " + --a);
