Write a void method called palindromeCheck that takes NO argument. The method should have functionality to check whether or not the word is a palindrome and print to the screen all of the palindromes, one per line. Also, the last line of the output should have the message: "There are x palindromes out of y words provided by user" (where x is the number of palindrome words detected, and y is the total number of words entered by user). Hint: for this lab exercise you will need the following methods on String objects: length () gives the length of a string (that is, the number of characters it contains) and charAt (i) - gives the character at position i.

import java. util. Scanner;

public class PalindromeCheck

{

public static void palindromeCheck ()

{

String someWord=" ";

int count=0;

int total=0;

System. out. println ("Ënter some words entered by whitespace");

Scanner keyboard = new Scanner (System. in);

String[] words=keyboard. nextLine (). split (" ");

for (int i=0; i
{

boolean flag=true;

int l=words[i]. length ();

for (int j=0; j<=l/2; j++)

{

if (words[i]. charAt (j) !=words[i]. charAt (l-j-1))

{

flag=false;

break;

}

}

if (flag)

count++;

}

System. out. println ("There are "+count+" palindromes out of "+words. length+" words");

keyboard. close ();

}

public static void main (String[] args)

{

palindromeCheck ();

}

}

Output

Ënter some words entered by whitespace

This is a malayalam.

There are 3 palindromes out of 4 words
