下面代码演示如何使用BufferedOutputStream类写文件。

使用BufferedOutputStream类写文件，需要先将字符串转换为字节数组，然后再写入。

import java.io.BufferedOutputStream;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;/** * * @author byrx.net */public class Main {    /**     * Prints some data to a file     */    public void writeToFile(String filename) {        BufferedOutputStream bufferedOutput = null;        try {            //Construct the BufferedOutputStream object            bufferedOutput = new BufferedOutputStream(new FileOutputStream(filename));            //Start writing to the output stream            bufferedOutput.write("Line one".getBytes());            bufferedOutput.write("\n".getBytes()); //new line, you might want to use \r\n if you're on Windows            bufferedOutput.write("Line two".getBytes());            bufferedOutput.write("\n".getBytes());            //prints the character that has the decimal value of 65            bufferedOutput.write(65);        } catch (FileNotFoundException ex) {            ex.printStackTrace();        } catch (IOException ex) {            ex.printStackTrace();        } finally {            //Close the BufferedOutputStream            try {                if (bufferedOutput != null) {                    bufferedOutput.flush();                    bufferedOutput.close();                }            } catch (IOException ex) {                ex.printStackTrace();            }        }    }    /**     * @param args the command line arguments     */    public static void main(String[] args) {        new Main().writeToFile("myFile.txt");    }}

运行上述代码，文件中的内容为：

Line oneLine twoA
