Java Palindrome Problem

It's an assignment I'm working on, I have to modify the code to eliminate the runtime error! It's prints true only if the palindrome has an odd length, false if it's no palindrome but error if it's a palindrome but has an even length. I tried changing the "i != j" in the while loop to "i <= j" and it stops the error but prints false for even length palindrome. Original code below 👇 https://code.sololearn.com/cLQ1Dlzp9WMn/?ref=app

Use condition i <= j And return i > j; let's see it works.

It not enough details to find mistakes.. Can you show your code by saving in playground..? edited:

For odd length ex: aba i != j becomes false and returns i==j true But for even length, Ex: abba, at end i=2 , j=1 when loop exits so return i==j returns false. you need to think about logic again.
