Java 字节流实现文件读写操作（InputStream-OutputStream）

备注：字节流比字符流底层，但是效率底下。

package com.frank.io;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;/** * author:pengyan  * date:Jun 15, 2011  * file:InputOutputStreamTest.java */public class InputOutputStreamTest{File f=new File("F:\\abc.txt");public static void main(String[] args) throws Exception{InputOutputStreamTest test=new InputOutputStreamTest();test.outputFile("Java字节流读写文件测试!");test.inputFile();}private void inputFile() throws IOException{//reate FileInputStream with fileFileInputStream fis=new FileInputStream(f);//in order to receive the value of this stream read every timeint temp=0;//the all content of this stream read String str="";while((temp=fis.read())!=-1){//if not end,the total content add the value of the stream read this timestr+=(char)temp;}//create a new String object with the correct encode System.out.println("文件内容："+new String(str.getBytes("ISO-8859-1")));}private void outputFile(String content) throws IOException {if (f.exists()==false) {f.createNewFile();//create file if not exist}//create FileOutputStream with fileFileOutputStream fos=new FileOutputStream(f);//output filefos.write(content.getBytes());//flush this streamfos.flush();//close this streamfos.close();}}
