键盘输入数组，然后输出最大

 1 public class Test01{
 2     public static void main(String[] args) {
 3         ArrayList<Integer> list=new ArrayList<Integer>();
 4         System.out.println("请输入数据：");
 5         while(true){
 6             Scanner sc=new Scanner(System.in);
 7             int num=sc.nextInt();
 8             if(num!=0){
 9                 list.add(num);
10             }else{
11                 System.out.println("over");
12                 break;
13                 
14             }
15             
16         }
17         Iterator<Integer> it=list.iterator();
18         while(it.hasNext()){
19             System.out.print(it.next());
20         }
21         
22         Integer[] i=new Integer[list.size()];
23         list.toArray(i);
24         
25         Arrays.sort(i);
26         System.out.println("the max is: "+i[i.length-1]);
27 
28         
29         
30     }
31 }
