Question

如题所述

Answer 1

文件路径自己改：
import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileReader;

import java.io.FileWriter;

import java.util.ArrayList;

public class TextReader {

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

FileReader reader = new FileReader(new File("test.txt")); // 输入文件

FileWriter writer = new FileWriter(new File("test1.txt")); // 输出文件

BufferedReader bReader = new BufferedReader(reader);

BufferedWriter bWriter = new BufferedWriter(writer);

String line = null;

String newLine = "\n";

ArrayList<String> output = new ArrayList<String>();

String subString = null;

String name = null;

String[] scores = null;

int sum = 0;

int max = 0;

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

System.out.println(line);

if (line.equals("#4")) {

output.add(line);

}

else {

int index = line.indexOf("#", 1);

name = line.substring(0, index + 1);

subString = line.substring(index + 1);

scores = subString.split("#");

for (String score : scores) {

sum += Integer.parseInt(score);

}

if (sum > max) {

max = sum;

output.add(1, name + sum);

}

else {

output.add(name + sum);

}

sum = 0;

}

}

for (String finalResult : output) {

System.out.println(finalResult);

bWriter.write(finalResult + newLine);

}

bReader.close();

bWriter.flush();

bWriter.close();

}

}追问

能给后面的加一点注释吗

追答

这个代码一目了然吧，你还有哪里不明白？

我修改了代码，私信给你了，查看下
