LinkedList를 활용한 Queue를 구현해 봅시다.

[샤키(sharky)]

Quiz> QueueTest1.java

class Warrior{

    int number;

    String name;

}

워리어 객체 3개를 만들어라. 

(1, "야만인전사")

(2, "휴먼전사")

(3, "마법전사")

LinkedList를 활용하여 순서대로 워리어 객체를 삽입하고

순서대로 출력해 보아라!. 단,) 입력은 0이 입력되면 종료된다.

-----------------------

[입력]

입력 : 1 야만인전사

입력 : 2 휴먼전사

입력 : 3 마법전사

입력 : 0 

입력종료!

[출력]

1 야만인전사

2 휴먼전사

3 마법전사
