我這里哪里錯了，自己編的程序看著差不多啊
package 我還是愛你的;
public class hg {
public static void main(String[] args){
int scores[]={61,23,4,74,13,148,20};
int max=scores[0];
int main=scores[6];
double sum=0;
double avg=0;
for(int i=0;i<=scores.length;i++){
if(max<scores[i]){
max=scores[i];
}else if(main>scores[i]){
main=scores[i];
}
sum=sum+scores[i];
}
avg=sum/scores.length;
System.out.println(sum);
System.out.println(avg);
}
}

public class hg {
public static void main(String[] args){
int scores[]={61,23,4,74,13,148,20};
int max=scores[0];
int main=scores[6];
double sum=0; ?（這里是整數(shù)求和 為什么用double 不用int？？？？？？？？）
double avg=0;

for(int i=0;i<=scores.length;i++)
少循環(huán)一次
改為 i<scores.length

for (int i = 0; i <= scores.length-1; i++) {

max = scores[i];
}?
if (min > scores[i]) {
min = scores[i];
}
sum = sum + scores[i];
}
avg = sum / scores.length;
System.out.println(sum);
System.out.println(avg);

main可以

不要用main吧。。main可以用？

不能等于代碼長度
