Submitted by Nidhi, on May 04, 2022

Problem statement

In this program, we will get the class loader of a class using the getClassLoader() method. The getClassLoader() method returns null for primitive types.

Source Code

The source code to print the class loader of the given class is given below. The given program is compiled and executed successfully.

// Java program to print the class loader of 
// the given class

public class Main {
  public static void main(String[] args) throws ClassNotFoundException {
    Class cls1 = Class.forName("Main");
    Class cls2 = Class.forName("java.lang.String");
    Class cls3 = int.class;

    System.out.println("The class loader associated with cls1: " + cls1.getClassLoader());
    System.out.println("The class loader associated with cls2: " + cls2.getClassLoader());
    System.out.println("The class loader associated with cls3: " + cls3.getClassLoader());
  }
}

Output

The class loader associated with cls1: jdk.internal.loader.ClassLoaders$AppClassLoader@4b85612c
The class loader associated with cls2: null
The class loader associated with cls3: null

Explanation

In the above program, we created a public class Main that contains a main() method. The main() method is the entry point for the program. Here, we get the class loader of the class using the getClassLoader() method and printed the result.
