Java Class desiredAssertionStatus() Method
Description
The Java Class desiredAssertionStatus() method returns the assertion status that would be assigned to this class if it were to be initialized at the time this method is invoked.
Declaration
Following is the declaration for java.lang.Class.desiredAssertionStatus() method
public boolean desiredAssertionStatus()
Parameters
NA
Return Value
This method returns the desired assertion status of the specified class.
Exception
NA
Getting Desired Assertion Status of a Class Example
The following example shows the usage of java.lang.Class.desiredAssertionStatus() method. In this program, we've created an instance of ClassDemo and then using getClass() method, the class of the instance is retrieved. Using desiredAssertionStatus(), we've retrieved desired assertion status and printed it.
package com.tutorialspoint; public class ClassDemo { public static void main(String[] args) { ClassDemo c = new ClassDemo(); Class cls = c.getClass(); // returns the name of the class String name = cls.getName(); System.out.println("Class Name = " + name); // returns assertion status boolean retval = cls.desiredAssertionStatus(); System.out.println("status = " + retval); } }
Output
Let us compile and run the above program, this will produce the following result −
Class Name = com.tutorialspoint.ClassDemo status = false
Getting Desired Assertion Status of a List Class Example
The following example shows the usage of java.lang.Class.desiredAssertionStatus() method. In this program, we've retrieved class of List Class. Now using desiredAssertionStatus(), we've retrieved desired assertion status and printed it.
package com.tutorialspoint; import java.util.List; public class ClassDemo { public static void main(String[] args) { Class cls = List.class; // returns the name of the class String name = cls.getName(); System.out.println("Class Name = " + name); // returns assertion status boolean retval = cls.desiredAssertionStatus(); System.out.println("status = " + retval); } }
Output
Let us compile and run the above program, this will produce the following result −
Class Name = java.util.List status = false
Getting Desired Assertion Status of a Integer Class Example
The following example shows the usage of java.lang.Class.desiredAssertionStatus() method. In this program, we've retrieved class of Integer Class. Now using desiredAssertionStatus(), we've retrieved desired assertion status and printed it.
package com.tutorialspoint; public class ClassDemo { public static void main(String[] args) { Class cls = Integer.class; // returns the name of the class String name = cls.getName(); System.out.println("Class Name = " + name); // returns assertion status boolean retval = cls.desiredAssertionStatus(); System.out.println("status = " + retval); } }
Output
Let us compile and run the above program, this will produce the following result −
Class Name = java.lang.Integer status = false
