J,K and L=5

M,N and O=6

P,Q,R and S=7

T,U,and V=8

W,X,Y and Z=9

Answer 1

5) Executable code:

import java.util.Scanner;

public class Wordseparator {

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);
       System.out.print("Enter the sentence: ");
       String s = scan.next();
       String resultStr = "";
       for (int i = 0; i < s.length(); i++) {
           char ch = s.charAt(i);
           if (i == 0) {
               resultStr = resultStr + String.valueOf(ch).toUpperCase();
           } else {
               if (Character.isUpperCase(ch)) {
                   resultStr = resultStr + " ";
               }
               resultStr = resultStr + String.valueOf(ch).toLowerCase();
           }
       }
       System.out.println(resultStr);
   }

}
