java程序纠错！！！！！！！！！！！！！！！

Question

import java.util.Scanner;
public class ArrayDefine{
public static void mian(String[] args){
Scanner sc = new Scanner(System.in);
double[] num = new double[4];
double average;
double sum=0;
for(int i=0;i<= 4;i++){
System.out.println("输入第"+(1+i)+"门课的成绩是；");
num[i] = sc.nextDouble();
System.out.println("输入的第"+(1+i)+"门课的成绩是"+num[i]);
sum+=num[i];
}//end of for
average = sum/5;
System.out.println("输入的");
System.out.println("所求的平均成绩是："+average);
}//end of main
}//end of class
菜鸟一个 能否详细解析下？

Answer 1

1
public static void mian(String[] args){
拼写错误，应该是main
2
for(int i=0;i<= 4;i++){
数组越界，应该是
for(int i=0;i< 4;i++){

完整代码如下：
import java.util.Scanner;
public class ArrayDefine{
public static void main(String[] args){
Scanner sc = new Scanner(System.in);
double[] num = new double[4];
double average;
double sum=0;
for(int i=0;i< 4;i++){
System.out.println("输入第"+(1+i)+"门课的成绩是；");
num[i] = sc.nextDouble();
System.out.println("输入的第"+(1+i)+"门课的成绩是"+num[i]);
sum+=num[i];
}//end of for
average = sum/5;
System.out.println("输入的");
System.out.println("所求的平均成绩是："+average);
}//end of main
}//end of class

Answer 2

public static void mian(String[] args){
兄弟or姐们 是main 不是mian

Answer 3

import java.util.Scanner;
public class ArrayDefine{
public static void mian(String[] args){ //main 方法好像写错了哥们
Scanner sc = new Scanner(System.in);
double[] num = new double[4];
double average;
double sum=0;
for(int i=0;i<= 4;i++){
System.out.println("输入第"+(1+i)+"门课的成绩是；");
num[i] = sc.nextDouble();
System.out.println("输入的第"+(1+i)+"门课的成绩是"+num[i]);
sum+=num[i];
}//end of for
average = sum/5;
System.out.println("输入的");
System.out.println("所求的平均成绩是："+average);
}//end of main
}//end of class
mian方法写错了是main不是mian ，其余的应该没什么问题了，有什么问题再来问我～

Answer 4

只是你MAIN写错了 其他正常编译 但是功能没实现

Answer 5

public static void mian(String[] args){
这个是main吧
