java.io.File寫入寫出的一個簡單實例

import Java.io.File;

import Java.io.FileInputStream;

import Java.io.FileNotFoundException;

import Java.io.FileOutputStream;

import Java.io.IOException;

public class TestIO {

/**

* @param args

*/

public static void main(String[] args)

{

// TODO Auto-generated method stub

byte[] b = new byte[17*1024];

// ** txt

// File f = new File("d:\\test.txt");

// File outF = new File("d:\\testOut.txt");

// ** jpg

File f = new File("d:\\毫無保留.jpg");

File outF = new File("d:\\毫無保留Output.jpg");

try

{

FileInputStream fis = new FileInputStream(f);

FileOutputStream fops = new FileOutputStream(outF);

fis.read(b);

fops.write(b);

// ** for see

// String s = new String(b);

// System.out.println(s);

fis.close();

fops.close();

}

catch(FileNotFoundException fnfe)

{

System.out.println("FileNotFoundException fnfe");

fnfe.printStackTrace();

}

catch(IOException IE)

{

System.out.println("IOException IE");

IE.printStackTrace();

}

}
