Java 中怎么利用Socket实现网络传输

package stream.demo;  import java.io.ByteArrayInputStream;  import java.io.ByteArrayOutputStream;  import java.io.File;  import java.io.FileInputStream;  import java.io.FileOutputStream;  import java.io.IOException;  import java.io.InputStream;  import java.io.ObjectInputStream;  import java.io.ObjectOutputStream;  import java.io.OutputStream;  import java.util.Date;  public class Persistence {  public static void main(String[] args) {  byte[] bs = Persistence.toBytes();  //在网络中进行传输  Persistence.getBytes(bs);  }  public static byte[] toBytes() {  Person p = new Person();  p.setName("corey");  p.setTall(171);  p.setBirthday(new Date());  p.setAddress(new Address("yiyang", "ziyang"));  ByteArrayOutputStream out = new ByteArrayOutputStream();  try {  ObjectOutputStream oout = new ObjectOutputStream(out);  oout.writeObject(p);  } catch (IOException e) {  // TODO Auto-generated catch block  e.printStackTrace();  }  return out.toByteArray();  }  public static void getBytes(byte[] bs) {  try {  ByteArrayInputStream byteIn = new ByteArrayInputStream(bs);  ObjectInputStream in = new ObjectInputStream(byteIn);  Person p = (Person) in.readObject();  System.out.println(p.getName());  System.out.println(p.getTall());  System.out.println(p.getBirthday());  System.out.println(p.getAddress().getCity());  System.out.print(p.getAddress().getStreet());  } catch (Exception e) {  // TODO Auto-generated catch block  e.printStackTrace();  }  }  } 

in = this.getRequestSocket().getInputStream();  out = this.getRequestSocket().getOutputStream();  byte[] bs = Persistence.toBytes();  System.out.println("发送数字长度："+bs.length);  out.write(bs);  this.getRequestSocket().close();  客户端代码片段为：  InputStream in = request.getInputStream();  byte[] bin = new byte[200];  int length = 0;  while ((length = in.read(bin)) != -1) {  System.out.println("length:" + length);  Persistence.getBytes(bin);  }
