Create a Hello World module

Create a Hello World module

We will now go through the creation of a module that will be the placeholder for a very simple program.

Name the module "Hello World" and put it in a helloworld directory under the root directory (compmodels) of the project.

addmodule

Accept to create a source directory named "src". Accept the default location for the compiler output path (classes). Your configuration will then look as follow:

paths

Create a new class by right-clicing on Hello World->helloworld->src and give it the name "HelloWorld".

newclass

Write the most simplistic program, such as:

        public class HelloWorld {
            public static void main(String[] args) {
                System.out.println("Hello World!");
            }
        }

Click on the down arrow in the tool bar and select "Edit Configurations". Add a configuration by clicking on the + button and name it "Hello World!". The main class should be HelloWorld and it should use the classpath and JDK of module "Hello World".

configurations

You are now ready to execute the program by selecting in the menu Run->Run... You should get a an output similar to this one:

helloworld
