Java Increments, Decrements and Operators

In This Example I'm Trying To Explain Pre-Increment , Post-Increment , Operators and How They Behave.

Following "JavaOpeartors.java" File Shows The Outputs.

class JavaOpeartors {
   public static void main(String args[]){
     
      int No1 = 10;
      System.out.print("Initial No1 : ");
      System.out.println(No1);
       
      ++No1;
      System.out.print("Pre Increment ++No1 : ");
      System.out.println(No1);

      System.out.print("Post Increment No1++ : ");

      System.out.println(No1++);

               System.out.print("After Post Increment No1 : ");

      System.out.println(No1);

      No1 = No1 + 3;

      System.out.print("No1 + 3 : ");
      System.out.println(No1);

      No1 += 10;

      System.out.print("No1 += 10 : ");
      System.out.println(No1);

      No1 -= 5;

      System.out.print("No1 -= 5 : ");
      System.out.println(No1);

      No1 *= 2;

      System.out.print("No1 *= 2 : ");
      System.out.println(No1);
   }
}

OutPut
Initial No1 : 10
Pre Increment ++No1 : 11
Post Increment No1++ : 11 
After Post Increment No1 : 12
No1 + 3 : 15
No1 += 10 : 25 
No1 -= 5 : 20 
No1 *= 2 : 40
