簡單的隊列運用

package com.geely.design.test;

import java.util.LinkedList;

public class MyQueue {
private LinkedList list=new LinkedList();
//隊尾插入
public void addLast(T v) {
list.addLast(v);
}
//取得對首元素
public T getFirst() {
return list.getFirst();
}
//移除隊首元素
public void remove() {
list.removeFirst();
}
}

public class Test {

public static void main(String[] args) {
    MyQueue<String>list=Test.print();
    System.out.println(list.getFirst());

}
public static MyQueue<String> print(){
    MyQueue<String>mq=new MyQueue<String>();
    mq.addLast("123");
    return  mq;
}

}
