Java中利用filereader和filewriter对文件进行处理1.0

说明：
1.按行解析文件，只对部分字符串分隔符进行拆分，具体可看代码
2.解析效率优化可自己探索

package com.zj.commons.fileutils;

import java.io.*;

public class FileUtils {

    private static final String fileSourcePath = "你要解析的文件路径";

    
    public static void processFile(String filePath, String separator) throws IOException {
        // 保存处理结果
        String result = "";

        // 读取文件
        FileReader fr = new FileReader(new File(fileSourcePath));
        BufferedReader br = new BufferedReader(fr);
        String line = br.readLine();
        while (line != null) {
            result += processWithSeparator(line, separator);
            line = br.readLine();
        }

        // 写入文件
        FileWriter fw = new FileWriter(new File("文件保存路径"));
        fw.write(result);
        fw.flush();
        fw.close();
    }

    private static String processWithSeparator(String line, String separator) {
        line = line.trim();
        // 以常见的字符串分隔符进行分割换行单独展示
        String[] sp = line.split(separator);
        String res = "";
        for (String item : sp) {
            res += item.trim() + "n";
        }
        return res;
    }

    
    public static void main(String[] args) throws IOException {
        processFile(fileSourcePath, " ");
    }


}
