Below programs demonstrate the desiredAssertionStatus() method.



Example 1:




// Java program to demonstrate
// desiredAssertionStatus() method
  
import java.util.*;
  
public class Test {
  
    public Object obj;
  
    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 Assertion Status of myClass
        // using desiredAssertionStatus() method
        System.out.println("Assertion Status of myClass: "
                           + myClass.desiredAssertionStatus());
    }
}
Output:
Class represented by myClass: class Test
Assertion Status of myClass: false

Example 2:




// Java program to demonstrate
// desiredAssertionStatus() method
  
import java.util.*;
  
class Main {
  
    private Object obj;
  
    public static void main(String[] args)
        throws ClassNotFoundException, NoSuchFieldException
    {
  
        try {
  
            // returns the Class object for this class
            Class myClass = Class.forName("Main");
  
            System.out.println("Class represented by myClass: "
                               + myClass.toString());
  
            // Get the Assertion Status of myClass
            // using desiredAssertionStatus() method
            System.out.println("Assertion Status of myClass: "
                               + myClass.desiredAssertionStatus());
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
