針對你的修改如下，你看看，
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.print("考試成績的前三名為：");
????????get(scores);???
????}
????
????//定義方法完成成績排序并輸出前三名的功能
????public?static?void?get(int?scores[]){
????????int?c;??????
????????for(int?i=0;i<scores.length-1;i++){?????
????????????for(int?j=i+1;j<scores.length;j++){
????????????????if(scores[i]<scores[j]){??//作為條件語句放在if里面
????????????????c=scores[i];
????????????????scores[i]=scores[j];
????????????????scores[j]=c;
????????????????}??????????
????????}
????????}
????????System.out.print(scores[0]+"?");
????????System.out.print(scores[1]+"?");
????????System.out.print(scores[2]);?
????}????
