How to create a Queue from LinkedList in Java?
Let us create a queue from LinkedList like this −
Queue<String>queue = new LinkedList<String>();
queue.add("P");
queue.add("Q");
queue.add("R");
queue.add("S");
queue.add("T");
queue.add("U");
queue.add("V");Now, use a List to display the elements of the queue −
List<String>list = new ArrayList<String>(queue);
Example
import java.util.ArrayList;
import java.util.LinkedList;
import java.util.List;
import java.util.Queue;
public class Demo {
public static void main(String[] args) {
Queue<String>queue = new LinkedList<String>();
queue.add("P");
queue.add("Q");
queue.add("R");
queue.add("S");
queue.add("T");
queue.add("U");
queue.add("V");
List<String>list = new ArrayList<String>(queue);
for (Object ob: list)
System.out.println(ob);
}
}Output
P Q R S T U V
