代码如下:

package CopyJavaPack01;

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;

public class CopyJavaDemo04 {
    public static void main(String[] args) throws IOException {
        BufferedWriter bw = new BufferedWriter(new FileWriter("D:\\\\JavaDemo\\\\bw.txt"));

        for (int i = 0;i<10;i++)
        {
            bw.write("hello"+i);
            bw.newLine();
            bw.flush();
        }

        bw.close();
    }

}

package CopyJavaPack01;

import java.io.*;

public class CopyJavaDemo04 {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new FileReader("D:\\\\JavaDemo\\\\java.txt"));

        String line;
        while((line=br.readLine())!=null)
        {
            System.out.println(line);
        }

        br.close();
    }

}
