Exercise 1

Task 1 - Print "Hello, World!"

Configuring Visual Studio Code for Java Development (EEE Lab and vLab Machines)

The EEE lab machines have the Java Runtime Environment (JRE) installed on the "Shared Drive". To allow the use of Visual Studio Code for programming in Java we need configure Visual Studio Code to use the JRE on the "Shared Drive" and install some plugins.

Below are some steps to run a Windows script to automatically configure the correct JRE path and install the necessary plugins for you.

Important

These steps are only for working on the QUB EEE lab and vLab machines

Warning

These steps will have to be repeated every time you log onto a new QUB EEE lab or vLab machine

  1. Open "Google Chrome" by double clicking on the Desktop icon:

  1. Go to /~https://github.com/dlim04/fundamentals-of-programming-for-engineers-labs/ and click dlim-configure-vscode-java.bat:

  1. Click the "Download raw file" button:

  1. Wait for the file to download and then open the file:

  1. Click More info:

  1. Click the "Run anyway" button:

  1. A terminal window should appear. Wait for the script to output "Complete!" and then press any key to close the teminal window:

You have now successfully configured Visual Studio Code for Java development.

Creating a Java Project and Running "Hello, World!"

  1. Open "Visual Studio Code":

  1. A "Getting Started with VS Code" tab may appear. Scroll down and click Mark Done:

  1. Click the "Explorer" button:

  1. Click the "Create Java Project" button:

  1. Click No build tools

  1. A window will appear asking you to select a location to create your Java project folder. In my case I chose to create a fundamentals-of-programming-for-engineers-labs folder in my Documents folder. If you wish to save your lab work across machines you may wish to choose the I: drive as the location to create your Java project folder. Click the "Select the project location" button:

  1. Type a name for your Java project and press the "Enter" key. Here I have chosen the name lab-1:

  1. Click src (shorthand for source) in the "Explorer" sidebar:

  1. Open App.java by clicking it:

  1. Click the "Run" button:

  1. A terminal should appear with "Hello , World!" printed in it:

You have successfully run "Hello, World!" in Java.
