缓冲读取缓冲输入

//缓冲输入用于对缓冲读取的写入

BufferedReader br = new BufferedReader(new FileReader("G:\aillo.txt"));

BufferedWriter bw = new BufferedWriter(new FileWriter("G:\jacky.txt"));

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

String strLine;

while(br.ready()){

　　strLine = br.readLine();

　　bw.write(strLine);

　　bw.newLine();

}

bw.flush();//刷新缓冲区，将该流输出到目的

bw.close();

br.close();

//应用实例:

import java.io.*;

public class test {
    public static void main(String args[]){
        File file = new File("G:\1.txt");
        File file2 = new File("G:\2.txt");
        try {
            BufferedReader br = new BufferedReader(new FileReader(file));
            BufferedWriter bw = new BufferedWriter(new FileWriter(file2));
            String strLine;
            
            while(br.ready()){
                strLine = br.readLine();
                System.out.println(strLine);
                bw.write(strLine);
                bw.newLine();
            }
            bw.flush();
　　　　　　　bw.close();
　　　　　　　br.close();
        } catch (FileNotFoundException e) {
            // TODO 自动生成的 catch 块
            e.printStackTrace();
        } catch (IOException e) {
            // TODO 自动生成的 catch 块
            e.printStackTrace();
        }
        
        
    }
