A self-explanatory COLLECTION of code and resources is called a MODULE. It adds a higher level of hierarchy above packages. A module is basically a uniquely named, RECLAIMABLE group of related packages, as well as resources (such as images and XML FILES) and a module descriptor.

Without further ado, let us go on and see the Steps to create a module in Java 9.

Let the name of our module be examplemodule.
Step 1: Create a folder:

C:\>Java\src 

The same folder is visible here:

Create a folder named examplemodule inside the src folder: 

The screenshot displays the same path:

Step 2: Create a module-info.java file in the C:\>Java\src\examplemodule folder with following code:

The screenshot:

Step 3: Create a file Example.java in the C:\Java\src\examplemodule folder.

The file has the following SOURCE code:

Step 4: Create a folder C:\Java\mods.

Create a folder name examplemodule in the mods folder. This is the same as the name of the module we have created.

Now compile the module to mods directory

Step 5: Let us run the module by running the following command

C:\Java>java --module-path mods -m examplemodule/examplemodule.Example

The module-path provides the module location as mods and -m signifies the main module.

The following is the output:
