用ArrayList儲存資料實現隊列功能(寫著玩的)__JAVA

package com.atguigu.java3;import java.util.ArrayList;public class MyQueue {private ArrayList list=new ArrayList();//入隊public void push(Object obj){list.add(obj);}//出隊public void pop(){Object obj=null;if(!list.isEmpty()){for(Object o:list){System.out.println(o);}}else{return;}}//擷取隊列長度public int getMyQueueLength(){return list.size();}//判斷隊列是否為空白public boolean isMyQueueEmpty(){return list.isEmpty();}}

測試類別：

<pre name="code" class="java">package com.atguigu.java3;public class MyQueueTest {public static void main(String[] args){MyQueue m=new MyQueue();m.push(12);m.push("sd");m.push("shfg");m.push(2);//System.out.println(m.getMyQueueLength());m.pop();}}
