Java的IO操作都是基于流进行操作的,为了提高读写效率一般需要进行缓冲。

/**
* 读出1.txt中的内容,写入2.txt中
*
*/
import java.io.*;
public class ReadWriteFile{
public static void main(String[] args){
try{
File read = new File("c:\1.txt");
File write = new File("c:\2.txt");
BufferedReader br = new BufferedReader(
new FileReader(read));
BufferedWriter bw = new BufferedWriter(
new FileWriter(write));
String temp = null;
temp = br.readLine();
