這樣做可以嗎

import?java.util.Arrays;
public?class?HelloWorld?{
????
????//完成?main?方法
????public?static?void?main(String[]?args)?{
????????int[]?scores?=?{89,-23,64,91,119,52,73};
????????System.out.println("考試成績(jī)的前三名為：");
????????HelloWorld?hello?=?new?HelloWorld();
????????hello.number(scores);
????????
????????
????}
????
????//定義方法完成成績(jī)排序并輸出前三名的功能
????public?void?number(int[]?scores){
????????Arrays.sort(scores);
????????int[]?num?=?new?int[3];
????????int?j?=?0;
????????for(int?i?=?scores.length-1;i?>=0;i--){
?????????if(scores[i]<100?&&?j<3?){
?????????????num[j]?=?scores[i];
?????????????j++;
?????????}
?????????else{
?????????????continue;
?????????}
????????}
????????System.out.println(num[0]);
????????System.out.println(num[1]);
????????System.out.println(num[2]);
????????
????????
????}
????
????
????
????
????
????
????
????
????
}
