Answer:

import java.util.Scanner;

public class num3 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter Favorite color");

       String word1 = in.next();

       System.out.println("Enter Pet's name");

       String word2 = in.next();

       System.out.println("Enter a number");

       int num = in.nextInt();

       //Point One

       System.out.println("You entered: "+word1+" "+word2+

               " "+num);

       //Point Two

       String passwordOne = word1+"_"+word2;

       String passwordTwo = num+word1+num;

       System.out.println("First password: "+passwordOne);

       System.out.println("Second password: "+passwordTwo);

       //Point Three

       int len_passwrdOne = passwordOne.length();

       int len_passwrdTwo = passwordTwo.length();

       System.out.println("Number of characters in "+passwordOne+" :" +

               " "+len_passwrdOne);

       System.out.println("Number of characters in "+passwordTwo+" :" +

               " "+len_passwrdTwo);

   }

}

Explanation:

  • This question is solved using java programming language
  • The scanner class is used to receive the three variables (Two string and one integer)
  • Once the values have been received and stored in the respective variables (word1, word2 and num), Use different string concatenation to get the desired output as required by the question.
  • String concatenation in Java is acheived with the plus (+) operator.
