Java Executor privilegedThreadFactory() Method

The privilegedThreadFactory() method of Executors class returns a thread factory used to create new threads that have the same permissions as the current thread. This factory creates threads with the same settings as defaultThreadFactory(), additionally setting the AccessControlContext and contextClassLoader of new threads to be the same as the thread invoking this privilegedThreadFactory method.

Example 1

  //import statement
  
    import java.util.concurrent.Executors;  
    import java.util.concurrent.ThreadFactory;  
      
    public class ExecutorsprivilegedThreadFactoryExample1  {  
       
        public static void main(String[] args) {  
            ThreadFactory thrdfctry = Executors.defaultThreadFactory();  
            Thread t = thrdfctry.newThread(new Mythrd3());  
            t.start();        
        }   
    }  
      
    class Mythrd3 implements Runnable {  
       
        @Override  
        public void run() {  
            System.out.println("Running thread concurrently");  
        }

Example 2

import java.util.Date;
    import java.util.concurrent.Executors;  
    import java.util.concurrent.ThreadFactory;  
      
    public class ExecutorsprivilegedThreadFactoryExample2  {  
       
        public static void main(String[] args) {  
            ThreadFactory thrdfctry = Executors.privilegedThreadFactory();
            for(int i=0 ; i<=5 ; i++){
            Thread t = thrdfctry.newThread(new Mythrd5());  
             t.start();        
        }
