Queue in Java
Learn the implementation of the queue in Java.
Using the add()
method
The Queue
interface and its implementations are different, although our algorithm has similarities with the Stack
interface. Let’s see a straightforward queue implementation where we’ve added a few elements. We’ve kept the code and the output in the same place.
The number of methods might seem daunting at first, but don’t worry. They become easier over time.

import java.util.LinkedList;import java.util.Queue;//Queue Example Oneclass Main{public static void main(String[] args) {Queue<String> letters = new LinkedList<String>();letters.add("A");letters.add("B");letters.add("C");letters.add("D");letters.add("E");letters.add("F");System.out.println(letters);}}
We get the following output when we run the code above:
[A, B, C, D, E, F]
Using the remove()
method
We can check whether a queue ...
