Palindrom of string in java

In this blog we will know whether a given string is palindrom or not.

Introduction 

 

In this blog, we will know whether a given string is palindrome or not.

 

A palindrome is a word, phrase, number that can be read the same way in either direction.

import java.util.*;
public class palindrom
{
 public static void main(String arg[])
 {
  System.out.println("Provide a string to test");
  Scanner sc = new Scanner(System.in);
  String str1 = sc.next();
  String str2 = "";
  for (int i = str1.length() - 1; i >= 0; i--)
   str2 = str2 + str1.charAt(i);
  if (str1.equals(str2))
   System.out.println("Palindrom");
  else
   System.out.println("Not a palindrom");
 }
}

Compile:-

 

javac palindrom.java

java palindrome

 

Ex: Provide a string to test:- BOB

Output:- String is palindrome
