Java-建立一个AnalysisResult类，对成绩进行分析

import java.io.*;
import java.util.*;
public class AnalysisResult {

    public static void main(String[] args) {
        File fRead= new File("C:\\Users\\17665\\Desktop\\score.txt");//txt的位置为文件的位置
        File fWrite= new File("socreAnalysis.txt");
        try {
            Writer out = new FileWriter(fWrite, true);
            BufferedWriter bufferWrite =new BufferedWriter(out);
            Reader in =new FileReader(fRead);
            BufferedReader bufferRead =new BufferedReader(in);
            String str =null;
            while((str=bufferRead.readLine())!=null) {
                double totalScore=Fenxi.getTotalScore(str);
                str =str+"总分："+totalScore;
                System.out.println(str);
                bufferWrite.write(str);

                System.out.println("平均分"+A);
                }
            bufferRead.close();

        catch(IOException e) {
            System.out.println(e.toString());
