priority threading in java code example

Example 1: priority queue in java

import java.util.PriorityQueue;
import java.util.Iterator;

class Main {
    public static void main(String[] args) {

        // Creating a priority queue
        PriorityQueue<Integer> numbers = new PriorityQueue<>();
        numbers.add(4);
        numbers.add(2);
        numbers.add(1);
        System.out.print("PriorityQueue using iterator(): ");

        //Using the iterator() method
        Iterator<Integer> iterate = numbers.iterator();
        while(iterate.hasNext()) {
            System.out.print(iterate.next());
            System.out.print(", ");
        }
    }
}

Example 2: thread priority in java

class TestMultiPriority1 extends Thread{  
 public void run(){  
   System.out.println("running thread name is:"+Thread.currentThread().getName());  
   System.out.println("running thread priority is:"+Thread.currentThread().getPriority());  
  
  }  
 public static void main(String args[]){  
  TestMultiPriority1 m1=new TestMultiPriority1();  
  TestMultiPriority1 m2=new TestMultiPriority1();  
  m1.setPriority(Thread.MIN_PRIORITY);  
  m2.setPriority(Thread.MAX_PRIORITY);  
  m1.start();  
  m2.start();  
   
 }  
}
