Getting Member Class Status of a Class Example

The following example shows the usage of java.lang.Class.isMemberClass() method. In this program, we've created an instance of ClassDemo and then using getClass() method, the class of the instance is retrieved. Using isMemberClass(), we've retrieved member class 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 true if and only if this class is a member class
      boolean retval = cls.isMemberClass();
      System.out.println("Is this MemberClass? " + retval);
   }
} 

Output

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

Class Name = ClassDemo
Is this MemberClass? false

Getting Member Class Status of an ArrayList Example

The following example shows the usage of java.lang.Class.isMemberClass() method. In this program, we've used class of an ArrayList. Using isMemberClass(), we've retrieved member class status and printed it.

package com.tutorialspoint;

import java.util.ArrayList;

public class ClassDemo {

   public static void main(String[] args) {

      Class cls = ArrayList.class;

      // returns the name of the class
      String name = cls.getName();
      System.out.println("Class Name = " + name);
     
      // returns true if and only if this class is a member class
      boolean retval = cls.isMemberClass();
      System.out.println("Is this MemberClass? " + retval);
   }
} 

Output

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

Class Name = java.util.ArrayList
Is this MemberClass? false

Getting Member Class Status of a Thread Example

The following example shows the usage of java.lang.Class.isMemberClass() method. In this program, we've used class of a Thread. Using isMemberClass(), we've retrieved member class status and printed it.

package com.tutorialspoint;

public class ClassDemo {

   public static void main(String[] args) {

      Class cls = Thread.class;

      // returns the name of the class
      String name = cls.getName();
      System.out.println("Class Name = " + name);
     
      // returns true if and only if this class is a member class
      boolean retval = cls.isMemberClass();
      System.out.println("Is this MemberClass? " + retval);
   }
} 

Output

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

Class Name = java.lang.Thread
Is this MemberClass? false
