Clearing Assertion Status of a ClassLoader Example

The following example shows the usage of java.lang.ClassLoader.clearAssertionStatus() method. In this program, we've retrieved class of a ClassLoaderDemo. Then using getClassLoader(), we get the required ClassLoader and printed class loader class using getClass() and printed the parent class loader using getParent() method. Now using clearAssertionStatus() method, we've clear class assertion status settings associated with the class loader.

package com.tutorialspoint;

public class ClassLoaderDemo {

   public static void main(String[] args) throws Exception {
     
      Class cls = Class.forName("com.tutorialspoint.ClassLoaderDemo");

      // returns the ClassLoader object associated with this Class
      ClassLoader cLoader = cls.getClassLoader();
    
      System.out.println(cLoader.getClass());
    
      // returns the parent ClassLoader
      System.out.println(cLoader.getParent());

      // sets the default assertion status to false
      cLoader.clearAssertionStatus();    
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

class jdk.internal.loader.ClassLoaders$AppClassLoader
jdk.internal.loader.ClassLoaders$PlatformClassLoader@4517d9a3
