The getModule() method of java.lang.Class class is used to get the module of this entity. This entity can be a class, an array, an interface, etc. The method returns the module of the entity.
Syntax: 
 

public Module getModule()

Parameter: This method does not accept any parameter.
Return Value: This method returns the module of the entity.
Below programs demonstrate the getModule() method.
Note: This method was introduced in Java 9. Hence to run this method, we need a compiler with Java 9. So this won’t run in the online IDE.
Example 1:
 

Java




// Java program to demonstrate getModule() method
 
public class Test {
    public static void main(String[] args)
        throws ClassNotFoundException
    {
 
        // returns the Class object for this class
        Class myClass = Class.forName("Test");
 
        System.out.println("Class represented by myClass: "
                           + myClass.toString());
 
        // Get the module of myClass
        // using getModule() method
        System.out.println("Module of myClass: "
                           + myClass.getModule());
    }
}

Output: 
 

Class represented by myClass: class Test
Module of myClass: unnamed module @23fc625e

Example 2:
 

Java




// Java program to demonstrate getModule() method
 
public class Test {
 
    class Arr {
    }
 
    public static void main(String[] args)
        throws ClassNotFoundException
    {
        // returns the Class object for Arr
        Class arrClass = Arr.class;
 
        // Get the module of arrClass
        // using getModule() method
        System.out.println("Module of arrClass: "
                           + arrClass.getModule());
    }
}

Output: 
 

Module of arrClass: unnamed module @23fc625e
