Question

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.

Answer 1

Answer:

Explanation:

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<words.length;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
