Java复制文件

package com;

import java.io.*;

public class CopyFIle {
    public static void main(String[] args) throws IOException {
        //利用 BufferedReader 读取需要复制的文件
        BufferedReader br = new BufferedReader(new FileReader("src/com/WriteFile.java"));
        //利用 BufferedWriter 将读到的文件存储到指定的文件中（文件存储在项目目录下）
        BufferedWriter bw = new BufferedWriter(new FileWriter("WriteFile2.java"));
        String line;
        while ((line = br.readLine()) != null) {
            bw.write(line);//一次写入一行数据
            bw.newLine();
            bw.flush();
        }
        bw.close();//依次释放资源
        br.close();
