你看一下這個吧：

import?java.util.Arrays;
public?class?HelloWorld?{
????
????//完成?main?方法
????public?static?void?main(String[]?args)?{
????int?[]scores?=?{89,-23,64,91,119,52,79};????
????
????System.out.println("?本次考試前三名是：");
????HelloWorld?hello?=?new?HelloWorld();????????
????hello.big3(scores);????
????}
????
????//定義方法完成成績排序并輸出前三名的功能
????
????public?void?big3(int?[]?scores)
????{
????????Arrays.sort(scores);
????????int?num?=?0;
????????for(int?i?=?scores.length-1;i>=0&&num<3;i--)
????????{
????????????if(scores[i]<0||scores[i]>100)
????????????????continue;
????????????num++;
????????????System.out.println(scores[i]);
????????}
????}
