java中讲讲FileWriter的用法，举例？

1.1 FileWriter的用法

FileWriter是Writer的继承类，从字面上就可看出，它的主要功能就是能向磁盘上写文件。write方法会把字符一个一个的写入磁盘中。

例：1.1.1

import java.io.*;

public class TestMark_to_win {

public static void main(String[] args) throws IOException {

File file = new File("c:\\test.txt");

FileWriter fw = new FileWriter(file);

/*void java.io.OutputStreamWriter.write(int c) throws IOException

Writes a single character.

Parameters:

c int specifying a character to be written*/

fw.write(97);

/*void java.io.Writer.write(String str) throws IOException

Writes a string.

Parameters:

str String to be written

*/

fw.write("this is 我们");

fw.close();

}

}

输出的结果是：

athis is 我们
