UDP传输
public class UDPSend {
public static void main(String[] args) throws IOException {
InetAddress ina=InetAddress.getLocalHost();
byte[] bytes="你好吗".getBytes();
DatagramSocket ds=new DatagramSocket();
DatagramPacket dp=new DatagramPacket(bytes, bytes.length,ina, 9528);
ds.send(dp);
ds.close();
}
}
UDP的接收
public class UDPRecieve { public static void main(String[] args) throws IOException { DatagramSocket ds=new DatagramSocket(9528); byte[] buf=new byte[1024]; int len=buf.length; DatagramPacket dp=new DatagramPacket(buf, len); ds.receive(dp); System.out.println(new String(buf,0,len)); ds.close(); } }
TCP的客户端
public class TCPClient {
public static void main(String[] args) throws IOException, IOException {
Socket socket=new Socket("192.168.1.123",3001);
OutputStream os=socket.getOutputStream();
FileInputStream fis=new FileInputStream("C:\\Users\\Rui\\Desktop\\read\\天际势力图.jpg");
int len=0;
byte[] bytes=new byte[1024];
while((len=fis.read(bytes))!=-1){
os.write(bytes);
}
socket.shutdownOutput();
InputStream in=socket.getInputStream();
len=in.read(bytes);
System.out.println(new String(bytes,0,len));
fis.close();
socket.close();
}
}
TCP的服务器端
public class TCPServer { public static void main(String[] args) throws IOException { ServerSocket server =new ServerSocket(7757); Socket socket=server.accept(); InputStream in=socket.getInputStream(); int len=0; byte[]bytes=new byte[1024]; File f=new File("C:\\Users\\Rui\\Desktop\\write\\write\\tnt.jpg"); FileOutputStream out=new FileOutputStream(f); while((len=in.read(bytes))!=-1){ out.write(bytes, 0, len); } OutputStream os=socket.getOutputStream(); os.write("传入成功".getBytes()); out.close(); socket.close(); server.close(); } }
TCP多线程接收信息的Runnable实现类
public class UPload implements Runnable {
private Socket socket;
private FileOutputStream out;
UPload(Socket socket){
this.socket=socket;
}
public void run() {
InputStream in;
try {
in = socket.getInputStream();
int len=0;
byte[]bytes=new byte[1024];
File f=new File("C:\\Users\\Rui\\Desktop\\write\\write\\tnt.jpg");
FileOutputStream out=new FileOutputStream(f);
while((len=in.read(bytes))!=-1){
out.write(bytes, 0, len);
}
OutputStream os=socket.getOutputStream();
os.write("传入成功".getBytes());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
