LinkedList link=new LinkedList();
Shop1 one=new Shop1(001,"苹果",3.2);
Shop1 two=new Shop1(002,"火龙果",3.88);
Shop1 three=new Shop1(003,"草莓",1.2);
Shop1 three1=new Shop1(003,"草莓",1.2);
Shop1 four=new Shop1(003,"小草",1.4);

    String a=Arrays.toString(link.toArray());
    System.out.println(a);

    Object[] x=link.toArray(new Object[5]);
    for(int i=0;i<link.size();i++){
        System.out.println(x[i]);
    }
