easy palindrome program in java

import java.util.*;

{  
   public static void main(String args[])  
   {  
      String original, reverse = ""; // Objects of String class  
      Scanner in = new Scanner(System.in);   
      System.out.println("Enter a string/number 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/number is a palindrome.");  
      else

   }  
}

import java.util.Scanner; public class Palindrome { public static void main(String args[]) { int num,temp,reverse=0; Scanner input=new Scanner(System.in); num=in.nextInt(); temp=num; //code to reverse the number while(temp!=0) { int d=temp%10; //extracts digit at the end reverse=reverse*10+d; temp/=10; //removes the digit at the end } // 'reverse' has the reverse version of the actual input, so we check if(reverse==num) { System.out.println("Number is palindrome"); } else { System.out.println("Number is not palindrome"); } } }

public static boolean checkPalindrome(String str) { int len = str.length(); for(int i = 0; i < len / 2; i++) { if (str.charAt(i) != str.charAt(len - i - 1)) return false; } return true; }

package test //The function below checks if a string is a palindrome //True = Is a palindrome & False = Not a palindrome public boolean isPalindromString(String text){ String reverse = reverse(text); if(text.equals(reverse)) { return true; } return false; } //This function returns the reverse String of its input. //Ex. if given "hello", it will return "olleh" public String reverse(String input) { if(input == null || input.isEmpty()) { return input; } return input.charAt(input.length()- 1) + reverse (input.substring(0, input.length() - 1)); }
