Palindrome program

package com.java;

import java.util.Scanner;


public class Palindrom {

  public static void main(String args[])
    {
       String original, reverse="";
       Scanner in = new Scanner(System.in);
  
       System.out.println("Enter a string to check if it is a palindrome : ");
       original = in.nextLine();
  
       int length = original.length();
  
       for ( int i = length - 1 ; i >= 0 ; i-- )
          reverse = reverse + original.charAt(i);
  
       if (original.equals(reverse))
          System.out.println("Entered string is a palindrome.");
       else
          System.out.println("Entered string is not a palindrome.");

   
    }

Swap Numbers without using third variable

package com.kota.java;

public class SwapNumbers {

  public static void main(String[] args) {
         
   int num1 = 10;
         int num2 = 20;
        
         System.out.println("Before Swapping");
         System.out.println("Value of num1 is :" + num1);
         System.out.println("Value of num2 is :" +num2);
        
         //add both the numbers and assign it to first
         num1 = num1 + num2;
         num2 = num1 - num2;
         num1 = num1 - num2;
        
         System.out.println("Before Swapping");
         System.out.println("Value of num1 is :" + num1);
         System.out.println("Value of num2 is :" +num2);

Swap Numbers using third variable

         swap(num1, num2);
 }

 private static void swap(int num1, int num2) {
        
         int temp = num1;

Program to generate Prime numbers.

package com.kota.java;

    BufferedReader bf = new BufferedReader(
    new InputStreamReader(System.in));
