例：

// Java Program is to demonstrate the example
// of Queue asLifoQueue(Deque d) method of Collections class
import java.util.*;
public class AsLifoQueue {
public static void main(String args[]) {
// Create a array deque object    
Deque de = new ArrayDeque(10);
// By using add() method is to add the
// given elements in linked list
de.add("C");
de.add("C++");
de.add("JAVA");
de.add("DOTNET");
de.add("PYTHON");
// Display Deque
System.out.println("de: " + de);
// By using asLifoQueue() method is to 
// represent the deque elements as lifo queue
Queue lifo_q = Collections.asLifoQueue(de);
System.out.println();
System.out.println("Collections.asLifoQueue(de) :");
// Display Queue
System.out.println("lifo_q: " + lifo_q);
}
}

Output
