Palindrome Program – Java

A palindrome is a string that is the same read forward or backward. For example, “dad” is the same in the forward or reverse direction. Another example is “aibohphobia”, which literally means, an irritable fear of palindromes.

import package Rootuser;

import java.util.Scanner;
public class Palindrome {
static void checkPalindrome(String input) {
//Assuming result to be true
boolean res = true;
int length = input.length();
//dividing the length of the string by 2 and comparing it.
for(int i=0; i<= length/2; i++) {
if(input.charAt(i) != input.charAt(length-i-1)) {
res = false;
break;
}
}
System.out.println(input + " is palindrome = "+res);
}
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.print("Enter your Statement: ");
String str = sc.nextLine();
//function call
checkPalindrome(str);

When you run the code, it will check whether the given string is a palindrome or not as shown below:

Enter your Statement: DAD
RACECAR is palindrome = true
 
Enter your Statement: RootUser
EDUREKA is palindrome = false
