1) To check weather a given string is palindrome or not in java.

Palindrome string a string which is same while reading from forward to backword or backword to forword (Ex. madam,lo,pop,rubber)

-To do that that there is very simple logic in java. 

1)We need to take a length of the string

2)Reverse a string

3)compare both the string

import java.util.Scanner;

public class Reversestring {

 public static void main(String[] args) {

  Scanner sc= new Scanner(System.in);
  System.out.println("enter the string: "); 
  String str=sc.next(); 
  int length=str.length();

  String s2="";

  for(int i=length-1;i>=0;i--)

   s2=s2+str.charAt(i);

  if(s2.equalsIgnoreCase(str))
  {
   System.out.println("palindrome");

  }
  else {
   System.out.println("not palindrom");
  }

 }

}
