Knock-Knock Lab

Overview

Create a version of the famous "Hello World" project - with a twist. Write a program that asks the user's name, greets the user by name, and tells a knock-knock joke.

Purpose

The purpose of this lab is to get you acquainted with programming in general, and Java in particular. The program itself is not complex, but there are many factors to writing it successfully:

• Installing the Java Development Kit
• Installing an editor
• Writing the program
• Compiling the program
• Viewing the output

The program

The actual program is quite simple. A transcript might look like this: (human input is in blue)

Hi, What's your name?
Andy
Here's a joke, Andy:
Knock knock
who's there?
Luke
Luke who?
Luke through the keyhole and you'll find out!
    

A perfect version of the program will do the following:

• Ask the user his or her name
• Repeat the user'sn name in a greeting
• Engage in an 'interactive' knock knock joke
• Take input for the user's part of the joke, but you don't really have to do anything with the information.

The program will require the following elements:

• A main method
• A Scanner variable for input
• A String variable for the user name
• (optional) a second string for other input
• A series of output statements (System.out.println)

Turning it in

Please name this program Knock.java. Compile the file and combine Knock.java and Knock.class in a zip file called userid_knock.zip. (userid will be your own userid of course.) Turn the program in via oncourse.
