  3. How to check a Palindrome through other ways?

 

Let’s begin,

1. What is Palindrome?

Palindrome is a word, phrase, or sequence that reads the same backward as forward, e.g., madam or level or radar etc.

Also, palindrome numbers are those numbers which represent same number if all digits are reversed. e.g., 10001

 

2. How to check Palindrome using Java 8?

Let’s say: In this particular example, we are checking if ‘radar’ & ‘apple’ are palindromes or not.

Example

 

Output:

 

3. How to check Palindrome through other ways?

Using For-Loop:

 

Using StringBuilder:

 

Using Apache StringUtils:

 

All the above ways of verifying the Palindrome will generate the same output. 

That’s it, Java 8 Streams API is so powerful and notice how easily it simplified the way of checking the Palindrome.
