The Java.util.PriorityQueue.add() method in Java is used to add a specific element into a PriorityQueue. This method internally just calls the Java.util.PriorityQueue.offer() method with the value passed to it. So, it exactly works like offer() method.
Syntax:
Java
Java
Priority_Queue.add(Object element)Parameters: The parameter element is of the type PriorityQueue and refers to the element to be added to the Queue. Return Value: The function returns True if the element is successfully added to the PriorityQueue . Below programs illustrate the Java.util.PriorityQueue.add() method: Program 1: Adding String elements into the Queue.
// Java code to illustrate add()
import java.util.PriorityQueue;
public class PriorityQueueDemo {
public static void main(String args[])
{
// Creating an empty PriorityQueue
PriorityQueue<String> queue = new PriorityQueue<String>();
// Use add() method to add elements into the Queue
queue.add("Welcome");
queue.add("To");
queue.add("Geeks");
queue.add("4");
queue.add("Geeks");
// Displaying the PriorityQueue
System.out.println("PriorityQueue: " + queue);
}
}
Output:
Program 2: Adding Integer elements into the Queue.
PriorityQueue: [4, Geeks, To, Welcome, Geeks]
// Java code to illustrate add()
import java.util.*;
public class PriorityQueueDemo {
public static void main(String args[])
{
// Creating an empty PriorityQueue
PriorityQueue<Integer> queue = new PriorityQueue<Integer>();
// Use add() method to add elements into the Queue
queue.add(10);
queue.add(15);
queue.add(30);
queue.add(20);
queue.add(5);
// Displaying the PriorityQueue
System.out.println("PriorityQueue: " + queue);
}
}
Output:
PriorityQueue: [5, 10, 30, 20, 15]
