PriorityQueue add() Method in Java
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:
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:
PriorityQueue: [4, Geeks, To, Welcome, Geeks]
Program 2: Adding Integer elements into the Queue.
// 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]
