datastreamtest.java

用java编写的一些初级代码

import java.io.*;
public class DataStreamTest
{
    public static void main(String []args)
    {
	try
	{
	    FileOutputStream fos=new FileOutputStream("./hell.txt");
	    BufferedOutputStream bos = new BufferedOutputStream(fos);
	    DataOutputStream dos = new DataOutputStream(bos);
	    dos.writeUTF("ab强迫");
	    dos.writeBytes("ab强迫");
	    dos.writeChars("ab强迫");
	    dos.close();

	    FileInputStream fis = new FileInputStream("./hell.txt");
	    BufferedInputStream bis = new BufferedInputStream(fis);
	    DataInputStream dis = new DataInputStream(bis);
	    System.out.println(dis.readUTF());
	    byte []buf =new byte[1024];
	    int len=dis.read(buf);
	    System.out.println(new String (buf,0,len));
	    fis.close();
	}
	catch(Exception e)
	{
	    System.out.println(e.getMessage());
	}
    }
}
