Java IO学习基础之读写文本文件(示例) （2）

/**
 * 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){

   File read = new File("c:\\1.txt");

   while(temp != null){
    //写文件
    bw.write(temp + "\r\n"); //只适用Windows系统
    //继续读文件
    temp = br.readLine();
   }
   
   bw.close();
   br.close();
   
  }catch(FileNotFoundException e){ //文件未找到
   System.out.println (e);
  }catch(IOException e){
   System.out.println (e);
