Introduction to Java for C$++$ Programmers

Please read the following guidelines very carefully before

answering any questions:

$$ You will at least define a class with the main method for each

question.

$$ You must keep the class name requested in each question.

$$ You must hold the naming conventions requested in this document

and each question.

$$ All deliverables are defined at the end of this document. You must

upload them as requested.

Typing quickly and correctly is an essential skill for working effectively with

computers and the Internet. In this question, you will build a GUI application to help

users learn to "touch type" $($i$.$e$.$ type correctly without looking at the keyboard$).$ The

application should display a virtual keyboard and allow the user to watch what they

are typing on the screen without looking at the physical keyboard. Use JButtons to

represent the keys. As the user presses each key, the application highlights the

corresponding JButton on the GUI and adds the character to a JTextArea that shows

what the user has typed so far. $[50$ Points$]$

Hint: To highlight a JButton, use its SetBackground method to change its

background colour. When the key is released, reset its original background colour.

Before changing, you can obtain the JButton's original background colour with the

getbackground method.

Note: You must use event$-$driven programming with the swing$$no credit for

JavaFX implementation.

Deliverables:

A$)$ Create an up to $15-$minute video $($only ONE video for all the questions$)$

explaining your answers, upload it on YouTube, and submit the link of your

video on Blackboard.

See "How to make a video and upload it on YouTube?" under the "Course

Information" on Blackboard.

Your video must at least contain the following content:

a$.$ Explaining the key components of your code and how they work.

b$.$ Showing three different runs and outputs of your code for each

question.

Note: There is no mark if you just read your code. You must explain your

code, not read it$.$

Note: Please DO NOT upload the original video file on Blackboard.

B$)$ You must upload all requested Java files $($i$.$e$."*.$java"$)$ as they are.

There is NO mark of you submitting any compressed file $($e$.$g$.$ zip, RAR,

etc.$)$

There is NO mark of you submitting $"*.$class" files.
