Question

You will write a single java program called MadLibs. java. This file will hold and allow access to the values needed to handle the details for a "MadLibs" game. This class will not contain a maino method. It will not ask the user for any input, nor will it display (via System.out.print/In()) information to the user. The job of this class is to manage information, not to interact with the user.

I am providing a MadLibsDriver.java e^{*} program that you can use to test your program. This class has a maino method and creates two instances of "MadLibs" objects. You do not need to change the driver program, although you are welcome to do so. Do not submit this program. Submit only the MadLibs. java program.

Your MadLibs. java program will require instance variables to store the following values:

HERE IS THE DRIVER:

import java.util.Scanner;

/**
 * MadLib driver.
 * 
 * @author nortonml
 * @version PA2
 */
public class MadLibsDriver {

    /**
     * The main method. 
     * 
     * @param args The command line arguments (unused)
     */
    public static void main( String[] args ) {
        
        double wage = 0.0;
        int hours = 0;
        
        Scanner scan = new Scanner( System.in );
        
        String person = "";
        String petName = "";
        String petType = "";        
        
        MadLibs test1 = new MadLibs();
        MadLibs test2 = new MadLibs( 21.3456, 30, "Tom", "Arial", 
                        "Mermaid" );
            
        System.out.println( test1 );   
        System.out.println();
        System.out.println( test2 );
        
        System.out.println( "Now it's your turn!!\n" );
        System.out.println( "Welcome to the CS149 MadLib Game\n" );
        
        System.out.print( "Enter a person's name: " );
        person = scan.nextLine();
        System.out.print( "Enter an unusual pet: " );
        petType = scan.nextLine();
        System.out.print( "Enter the pet's name: " );
        petName = scan.nextLine();
        System.out.print( "Enter an hourly wage: " );
        wage = scan.nextDouble();
        System.out.print( "Enter the hours worked: " );
        hours = scan.nextInt();
        
        test1.setHourlyWage( wage );
        test1.setHoursWorked( hours );
        test1.setPersonName( person );
        test1.setPetName( petName );
        test1.setPetType( petType );
        
        System.out.println();
        System.out.println( test1 );

    }
