使用LinkedList模仿队列

package other;import java.util.LinkedList;public class DuiLie {    private LinkedList link;    DuiLie(){        link = new LinkedList<>();    }    public void myAdd(Object obj){        link.addLast(obj);    }    public Object myGet(){        return link.removeFirst();    }    public boolean isEmpty(){        return link.isEmpty();    }    public static void main(String[] args) {        DuiLie d = new DuiLie();        d.myAdd("abc1");        d.myAdd("abc2");        d.myAdd("abc3");        d.myAdd("abc4");        while(!d.isEmpty()){            System.out.println(d.myGet());        }    }}
