import java.util.Arrays;

public class HelloWorld {

//完成 main 方法

public static void main(String[] args) {

HelloWorld hello= new HelloWorld();

int[] scores={89,-23,64,91,119,52,73};

int count=0;

hello.ranks(scores);

public void ranks(int[] ranks){

int[] ranks1=Arrays.sort(ranks);

outer:

for(int i =ranks1.length-1;i>=0;i--){

if(ranks[i]<0|| ranks[i]>100){

continue;

}

count++;

System.out.println("考试的前三名为：");

System.out.println(ranks1[i]);

if(count>3){

break outer;

}

    public static void ranks(int[] ranks){
            Arrays.sort(ranks);
            System.out.println("考试的前三名为：");
            outer:for(int i=ranks.length-1,count=0; ;i--){
                if(ranks[i]<0|| ranks[i]>100){
                    continue;
                }
                else
                {
                    count++;
                }
                
                System.out.println(ranks[i]);
                if(count>=3){
                    break outer;
                }
            }
        }

改了下 ranks方法正常了

括号的问题，你看下你的main方法的最后一个大括号在哪？
