In this example we shall show you how to create a client Socket with timeout. A client socket is an endpoint for communication between two machines. To create a client socket with timeout one should perform the following steps:
- Get the InetAddress of a specified host, using the host’s name, with
getByName(String host)API method of InetAddress. - Create a new InetSocketAddress that implements an IP Socket Address, with the InetAddress and the port.
- Create a new Socket and connect it to the server with a specified timeout value, using
connect(SocketAddress endpoint, int timeout)API method of Socket. If timeout occurs, a SocketTimeoutException is thrown,
as described in the code snippet below.
package com.javacodegeeks.snippets.core;
import java.io.IOException;
import java.net.InetAddress;
import java.net.InetSocketAddress;
import java.net.Socket;
import java.net.SocketAddress;
import java.net.UnknownHostException;
public class CreateClientSocketWithTimeout {
public static void main(String[] args) {
try {
InetAddress addr = InetAddress.getByName("javacodegeeks.com");
int port = 80;
SocketAddress sockaddr = new InetSocketAddress(addr, port);
// Creates an unconnected socket
Socket socket = new Socket();
int timeout = 5000; // 5000 millis = 5 seconds
// Connects this socket to the server with a specified timeout value
// If timeout occurs, SocketTimeoutException is thrown
socket.connect(sockaddr, timeout);
System.out.println("Socket connected..." + socket);
}
catch (UnknownHostException e) {
System.out.println("Host not found: " + e.getMessage());
}
catch (IOException ioe) {
System.out.println("I/O Error " + ioe.getMessage());
}
}
}
Output:
Socket connected... Socket[addr=javacodegeeks.com/216.239.34.21,port=80,localport=58897]
This was an example of how to create a client socket with timeout in Java.
Worked in android, thanks!
