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 objectbufferedOutput = new BufferedOutputStream(new FileOutputStream(filename));//Start writing to the output streambufferedOutput.write("Line one".getBytes());bufferedOutput.write("\n".getBytes()); //new line, you might want to use \r\n if you're on WindowsbufferedOutput.write("Line two".getBytes());bufferedOutput.write("\n".getBytes());//prints the character that has the decimal value of 65bufferedOutput.write(65);} catch (FileNotFoundException ex) {ex.printStackTrace();} catch (IOException ex) {ex.printStackTrace();} finally {//Close the BufferedOutputStreamtry {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");}}
