NA

Return Value

This method returns the int representing the modifiers for this class.

Exception

NA

Getting Modifiers of a Class Example

The following example shows the usage of java.lang.Class.getModifiers() method. In this program, we've created an instance of ClassDemo and then using getClass() method, the class of the instance is retrieved. Using getModifiers(), we've retrieved the modifier and then printed its name.

package com.tutorialspoint;

import java.lang.reflect.Modifier;

public class ClassDemo {

   public static void main(String[] args) {

      ClassDemo c = new ClassDemo();
      Class cls = c.getClass();

      // returns the Java language modifiers for this class
      int i = cls.getModifiers();
      String retval = Modifier.toString(i);
      System.out.println("Class Modifier = " + retval);
   }
} 

Output

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

Class Modifier = public

import java.lang.reflect.Modifier;
import java.util.ArrayList;

public class ClassDemo {

   public static void main(String[] args) {

      Class cls = ArrayList.class;

      // returns the Java language modifiers for this class
      int i = cls.getModifiers();
      String retval = Modifier.toString(i);
      System.out.println("Class Modifier = " + retval);
   }
} 

Output

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

Class Modifier = public

Getting Modifiers of Thread Example

The following example shows the usage of java.lang.Class.getModifiers() method. In this program, we've used class of Thread. Using getModifiers(), we've retrieved the modifier and then printed its name.

package com.tutorialspoint;

import java.lang.reflect.Modifier;

public class ClassDemo {

   public static void main(String[] args) {

      Class cls = Thread.class;

      // returns the Java language modifiers for this class
      int i = cls.getModifiers();
      String retval = Modifier.toString(i);
      System.out.println("Class Modifier = " + retval);
   }
} 

Output

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

Class Modifier = public
