Class desiredAssertionStatus() method in Java with Examples

The desiredAssertionStatus() method of java.lang.Class class is used to get the Assertion Status of this class, that would get assigned to the class when this method gets invoked. The method returns the Assertion Status of this class in the form of a boolean value.

Syntax:

public boolean desiredAssertionStatus()

Parameter: This method does not accepts any parameter

Return Value: This method returns the specified Assertion Status of this class in the form of a boolean value.

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);
        }
    }
}

Output:

Class represented by myClass: class Main
Assertion Status of myClass: false
