How to check whether given String is palindrome or not in Java?



Problem Description :


Write a program in Java that checks whether given String is palindrome or not.

If any string is same from both the sides then we can say, string is palindrome. For example - "raman" is not a palindrome but "naman" is palindrome. There are 2 ways to check whether string is palindrome or not. Library function and Iteration. We will discuss both methods here.

1) Library function


Here we are finding reverse of string using library function of StringBuilder class and then comparing given string with reversed string.



2) Iteration


Here we are using for loop and comparing first and last character of string till its half length.



Output :


Case 1 :


Output of Java program that checks whether given string is Palindrome or not - Case1
Output - String is not Palindrome.


Case 2 :


Output of Java program that checks whether given string is Palindrome or not - Case2
Output - String is Palindrome.
