Class getModule() method in Java with Examples (original) (raw)

Last Updated : 27 Jan, 2022

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

public class Test {

`` public static void main(String[] args)

`` throws ClassNotFoundException

`` {

`` Class myClass = Class.forName("Test");

`` System.out.println("Class represented by myClass: "

`` + myClass.toString());

`` System.out.println("Module of myClass: "

`` + myClass.getModule());

`` }

}

Output:

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

Example 2:

Java

public class Test {

`` class Arr {

`` }

`` public static void main(String[] args)

`` throws ClassNotFoundException

`` {

`` Class arrClass = Arr. class ;

`` System.out.println("Module of arrClass: "

`` + arrClass.getModule());

`` }

}

Output:

Module of arrClass: unnamed module @23fc625e
