Answer 1

The program in Java to display all the palindrome words in a string entered is shown below:

import java.util.Scanner;

public class KboatPalinWords

{

   public static void main(String args[])

{

      Scanner in = new Scanner(System.in);

      System.out.println("Please enter a sentence:");

      str = str + " ";

      String word = "";

      int len = str.length();

     

      for (int i = 0; i < len; i++)

 {

          char ch = str.charAt(i);

          if (ch == ' ')

    {

              int wordLen = word.length();

              boolean isPalin = true;

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

       {

                  if (word.charAt(j) != word.charAt(wordLen - 1 - j))

           {

                      isPalin = false;

                      break;

                  }

              }

               if (isPalin)

                    System.out.println(word);

                    word = "";

               }

          else

          {

              word += ch;

          }

      }

   }

}

Output:

Please enter a sentence: MOM AND DAD ARE NOT AT HOME

Output: MOM DAD
