源程序Bwriter.java(从键盘输入一系列字符串，写入到某磁盘文件中）

源程序Bwriter.java

import java.io.*;
public class Bwriter
{
public static void main(String args[]) throws Exception
{InputStreamReader i = new InputStreamReader(System.in);
BufferedReader b = new BufferedReader(i);
FileWriter f = new FileWriter("file1.txt");
BufferedWriter w = new BufferedWriter(f);
String s;
while(true)
{
System.out.print("input a string :");
System.out.flush();
s = b.readLine();
if(s.length() == 0)
break; //如果用户直接回车，代表结束
w.write(s);
w.newLine();
}
w.close();
}
}
输出结果：



编程后感：

1）看到不懂的问题问问同学或者上网百度；

2）老师教导，多敲代码，果真有效；
