An array Deque can easily be created in Java. You only need to import the java.util.ArrayDeque package. After import, create the array Deque as follows:
|
ArrayDeque<Type> name_of_array_Deque = new ArrayDeque<>(); |
You can create either a string or an integer ArrayDeque. For instance
|
// A String type ArrayDeque<String> students = new ArrayDeque<>(); // Integer type ArrayDeque<Integer> marks = new ArrayDeque<>();
|
For this example, we will create an ArrayDeque and add three students by using the add(), addFirst(), and addLast() methods.
|
import java.util.ArrayDeque; public class ArrayDequeClass { public static void main(String[] args) { ArrayDeque<String> students= new ArrayDeque<>(); // Add first student using add() students.add("Rajkmaar"); // Add second student using addFirst() students.addFirst("Rohit"); // Add third student using addLast() students.addLast("Thakur"); System.out.println("ArrayDeque: " + students); } } |
Output:
ArrayDeque: [Rohit, Rajkmaar, Thakur]
