Enter favorite color:
yellow
Enter pet's name:
Daisy
Enter a number:
6
You entered: yellow Daisy 6

(2) Output two passwords using a combination of the user input. Format the passwords as shown below. (Submit for 2 points, so 3 points total).

Enter favorite color:
yellow
Enter pet's name:
Daisy
Enter a number:
6
You entered: yellow Daisy 6

First password: yellow_Daisy
Second password: 6yellow6

(3) Output the length of each password (the number of characters in the strings). (Submit for 2 points, so 5 points total).

Enter favorite color:
yellow
Enter pet's name:
Daisy
Enter a number:
6
You entered: yellow Daisy 6

First password: yellow_Daisy
Second password: 6yellow6

Number of characters in yellow_Daisy: 12
Number of characters in 6yellow6: 8

Answer 1

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.
