A program to Swap the values

class SwapTheValues{

      public static void main(String args[]){

      int num1 = Integer.parseInt(args[0]);

      int num2 = Integer.parseInt(args[1]);

      System.out.println("\n***Before Swapping***");

      System.out.println("Number 1 : "+num1);

      System.out.println("Number 2 : "+num2);

      //Swap logic

      num1 = num1 + num2;

      num2 = num1 - num2;

      num1 = num1 - num2;

      System.out.println("\n***After Swapping***");

      System.out.println("Number 1 : "+num1);

      System.out.println("Number 2 : "+num2);

      }

}

A program that will read a float type value

class ValueRead{

  public static void main(String args[]){

       double i = 34.32;

System.out.println("Small Int. not greater than the no. : "+Math.ceil(i));

    System.out.println("Given Number : "+i);

System.out.println("Largest Int. not greater than the no. : "+Math.floor(i));

  }
