Question

As a twist on the Hello World exercise, you are going to be the end user of the Hello class. This class is designed to greet the user in a variety of world languages. For this task, complete the following:
Use the Scanner class to ask the user for their name.
Create a Hello object by passing the name to the constructor.
Call at least 3 methods from the Hello class to print the greeting in 3 different languages.
Remember to write your code in the HelloTester class, but make sure you take a look at the Hello class so that you know the names of the methods you need to use.

Answer 1

Answer:

Here is the Hello class:

public class Hello { //class name

     private String name; //to store the name

     

      public Hello (String names) //parameterized constructor

      { name = names;  }  

     

      public void English() { //method to greet user in english

           System.out.print("Hello "); //displays Hello on output screen

           System.out.print(name); //displays user name

           System.out.println("!");  }  //displays exclamation mark symbol

           

           public void Spanish(){ //method to greet user in spanish

               System.out.print("Hola "); //displays Hello on output screen

               System.out.print(name); //displays user name

               System.out.println("!"); } //displays exclamation mark symbol

           

         public void French() { //method to greet user in french

              System.out.print("Bonjour "); //displays Hello on output screen

              System.out.print(name);  //displays user name

              System.out.println("!");  } } //displays exclamation mark symbol

           

Explanation:

Here is the HelloTester class:

import java.util.Scanner; //to accept input from user

public class HelloTester { //class name

 public static void main (String[]args)  { //start of main method

String name; //to store the name of user

Scanner input = new Scanner(System.in);  //creates Scanner class object

System.out.println("Enter name?" );  //prompts user to enter name

 name = input.nextLine(); //scans and reads the name from user

 Hello hello = new Hello(name); //creates Hello class object and calls constructor by passing name

hello.English(); //calls English method using object hello to greet in english

hello.Spanish(); //calls Spanish method using object hello to greet in spanish

hello.French(); } }  //calls French method using object hello to greet in french

The output of the program is:

Enter name?                                                                                                                    user                                                                                                                           Hello user!                                                                                                                    Hola user!                                                                                                                    Bonjour user!
