Java program to check if a string is a palindrome or not, it’s a palindrome if it remains the same on reversal.
For example, “dad” is a palindrome, as its reverse is “dad,” whereas “program” isn’t, as its reverse is “margorp” that is different from “program.”
Some palindrome strings examples are: “j”, “mom”, “madam”, “ab1ba”, “12321.”
In the program, a user inputs a string, and we create a new one by reversing it and then compares it with the input string.
