求大神帮我看看哪里错了
package a22; import java.util.Arrays; public class Lian9 { public static void main(String[] args) { int []scores= {89 , -23 , 64 , 91 , 119 , 52 , 73}; Lian9 hello=new Lian9(); System.out.println("考试成绩的前3名为:"); hello.text(scores); } public void text(int [] scores) { Arrays.sort(scores); int num=0; for(int i=scores.length;i>=0;i--) { if(scores[i]>=0&&scores[i]<=100 ) { num++; } System.out.println(scores[i]); if(num>2) { break; } } } }
运行结果是这样的:
考试成绩的前3名为:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 7
