Learning Outcomes

By completing the assigned exercises of this lab, you are expected to be able to:

1. Use simple Linux commands on a terminal.
2. Exercise a simple workflow of Github.
3. In the Eclipse IDE (Integrated Development Environment):
   • Create a new Java project.
   • Create a new Java class serving as a console application (with the main method).
   • Create a new Java class serving as a holder of utility methods.
   • Write Java programs composed of:
     • Numerical Literals and operators
     • String Literals and operators
     • Variables
     • Console outputs (via out.println)
     • Keyboard inputs (via nextInt(), nextDouble(), and nextLine() of Scanner)
   • Run a Java class with with the main method as a console Java application.
   • Implement utility methods (called by the console applications).
   • Write a JUnit test (calling the utility methods)
   • Export an existing project as an archive file.
4. Understand the separation of concerns (using packages): model, consoleapps, and junittests.

1 Task 1: Creating a Github Account to Manage Software Projects

Though it is not required, it is highly recommended that you adapt to to the practice of managing your software projects using Github.

• If you already have a Github account, make sure that you are able to create private Otherwise, you are still required to create an Educational account for this course.

Requirement: You must create an Educational Github account, e.g., with a user name structured as follows (separated by single hyphens):

lastName-firstName

For example: smith-john would be the Github account name for a student whose last name is Smith and first name is John.

• Follow this tutorial series to learn about applying and using an Educational Github account (and creating private repositories):

Notes:

• Skip Video 05, which is not applicable for this course.

Video 06

• is for you to synchronize between your Github repositories and your own computer . It is assumed that you already installed the Github desktop program on your own computer.

2 Task 2: Installing and Launching Eclipse on Your Own Computer

There is one item to install on your laptops in order to construct Java programs:

Eclipse IDE 202012 (using the Eclipse Installer 202012 R) [click on the blue link]

To launch Eclipse, simply click on its icon:

You should be able to see an initial prompt like:

• If you are able to see the above Eclipse initial prompt, then you are ready! See the next section for tutorial videos to get started with programming in Java.

3 Task 3: Tutorial Videos to Complete

Here is a tutorial series for you to obtain hands-on experience on the basics of Java programming:

https://www.youtube.com/playlist?list=PL5dxAmCmjv_6wy2m0yq2wObIWPz4tAxW6

The above tutorial series will be expanded with videos on a weekly basis to supplement your lectures.

• As you study through the example Java classes in the tutorial videos, you are required to type them out (but absolutely feel free to add new Java classes to experiment) on Eclipse.
• To submit for Lab0, complete the study of Week 01 videos (Parts A F). You are expected to re-produce all Java classes demonstrated in the tutorials.

Spellings of names of the packages, files, classes, and methods must be exact (and casesensitive), as we will run some automatic checks to grade the submitted files.

• No additional exercises are required for Lab0 submission. You can find the iPad notes illustrated in the tutorial videos here:

4 Submission

1. Part F of Week 01s tutorial videos asks you to export the Java project as an archive file:

EECS1022W21Week01.zip

Before you submit, verify that its unzipped version has the following structure (the bin directory may be ignored; the src folder structure must be exact):

Figure 1: Lab0 Expected Project Structure

Names of the packages, files, classes, and methods must be exact (and case-sensitive), as we will run some automatic checks to grade the submitted files.

e.g., If you have a class ConsolApp2 rather than ConsoleApp2, its considered as wrong.

2. Go to the eClass site for Sections M,N,O: https://eclass.yorku.ca/eclass/course/view.php?id=6214
3. Under the Lab Submissions section, click on Lab0 to submit the Java archive file:

EECS1022W21Week01.zip:

• You may upload as many draft versions as you like before the deadline.
• You must explicitly submit the draft version for grading before the deadline.
• Once you click on the submit button, you can no longer upload another draft version.

5 Appendix: Basic Commands on a Terminal

cd

Change to a directory

e.g., cd

e.g., cd /Desktop

e.g., cd /Desktop/EECS1022-W21-workspace

• pwd

Return the path of the current directory.

• ls

List the contents of the current directory.

6 Appendix: A Simple Github Workflow

• Create a private repository (e.g., EECS1022-W21-workspace) dedicated for all labs of this course.
• Clone a copy of some repository:

git clone

where is the URL of the repository that can be copied from a web browser.

• Make some changes to the clone copy (e.g., a new Java project, a new Java class, a change to an existing

Java class).

• Add all changes to the local change list:

git add *

• Commit the change list locally:

git commit -m

where is some meaningful and informative log message.

• Push the local committed change to the online repository:

git push

Then enter your git account username and password.
