java - 从文件中读取String和Int，然后循环遍历？

Question

我试图得到它，所以当它读取文件时，它将逗号之前的所有内容拆分为一个元素，然后由于有 10 个整数等级，因此需要将它们解析为 int，然后计算平均。但是，我不确定如何实际实现这一目标。我已经寻找解决方案几个小时了，但我似乎无法弄清楚。我真的很感谢这里的一些帮助，因为我目前的脑细胞已经耗尽了。谢谢您，- 来自编程新手。

我正在读取的 .txt 文件: /image/nxCi4.png

我当前的代码:

public class Main {

    public static void main(String[] args) throws IOException {

        Scanner scanner = new Scanner(System.in);
        String userInput;
        System.out.println("Enter raw grades filename:");
        userInput = scanner.nextLine();

        BufferedReader br = new BufferedReader(new FileReader(userInput));

        String line = "";
        String txtSplitBy = ", ";

        while ((line = br.readLine()) != null) {

        String[] splitLine = line.split(", ");
        String name = splitLine[0];
        String scores = splitLine[2];

        int i = Integer.parseInt(scores);

        }
    }
}

Answer 1

BufferedReader br = new BufferedReader(new FileReader(userInput));

String line;
String txtSplitBy = ",";

while ((line = br.readLine()) != null) {
    int score = 0;
    String grade;
    String[] splitLine = line.split(txtSplitBy);
    String name = splitLine[0];
    for ( int i =1; i <= 10; i++) {
        score += Integer.parseInt(splitLine[i]);
    }
    if ( score < 50 ) {
        grade = "B";
    }else if ( score < 60 ) {
        grade = "A";
    }else {
        grade = "S";
    }
    System.out.println(name +"," + (score/10) + "," + grade );
}
