我的方法没有运行很多错误

Question

public static double calcAverage (int [] high)
{
double sum = 0;
double result;
for (int i=0; i < high.length; i++)
{
sum = sum + high[i];
}
result = sum / high.length;
// return results
return result;
}

试试这个：

public class NewJavaProgram {

    public static double calcAverage (int [] high) {

        double sum = 0;
        double result;

        for (int i=0; i < high.length; i++) {
            sum = sum + high[i];
        }
        result = sum / high.length;
        // return results
        return result;
    }

    public static void main(String [] args) {
        int [] i=new int[10];
        System.out.println(NewJavaProgram.calcAverage(i));
    }

}
