Exercise: IntelliJ

Up until this point, we've worked with very simple scripts. We have been able to write these in a simple text editor, and then compile and run them using the terminal CLI. But as we start to work on more complex applications, we will want a more sophisticated development environment. So from now on, we'll be doing all of the exercises in the free Community edition of the IntelliJ IDEA. If you didn't download and install this back in the previous lesson, you should go ahead and do it now!

ND079 C1 L1 A13 JAVA Walkthrough

IntelliJ

Task Description:

Before going any further, make sure you've tried out all of the following steps in IntelliJ:

Task List:

Launch the Intelij IDE.

Select Create new Project.

Select Java and press the Next button.

IntelliJ will ak if you want to create the project from a template. In this case, we do not, so simply leave this option unchecked and click Next.

Enter the name of the project, myFirstProject . Typically project names start with a lower case letter, capitalize the first letter of each word after the first, and do not contain spaces.

Expand the project you just created until you see the src file. Your code will exist in this folder.

Create a new package by right clicking the src folder and selecting New > Package. You can name the new package code.

Right click the code package and select New > Java class. Name the class FirstClass. Notice that for a class name, the convention is to capitalize the first letter.

Next, create the main method and add the console print command inside the main method brackets System.out.println("My first Java Application");

Run the code. You should see your message printed in the output.

Task Feedback:

Nice work!

Solution

package code;

public class FirstClass {
