Java ServerSocket getSoTimeout() Method

The getSoTimeout() method of ServerSocket class is used to enable/disable SO_TIMEOUT with the specified timeout, in milliseconds.

If the timeout expires, a java.net.SocketTimeoutException is raised, though the ServerSocket is still valid.

Syntax

Returns:

The SO_TIMEOUT value

Throws:

IOException - if an I/O error occurs

Since:

1.1

Example 1

ServerApplication:

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.SocketTimeoutException;

public class SocketGetSoTimeout1 extends Thread{
		private ServerSocket socket;
		public SocketGetSoTimeout1()  throws IOException {
		  socket = new ServerSocket(1408);
		  socket.setSoTimeout(10000);    
	      System.out.println("Socket time out in "+socket.getSoTimeout()+"ms");
	  }
	  public void run() {
	    while (true) {
	      try {
	        System.out.println("Connecting .........");
	        Socket client = socket.accept();
	        System.out.println("Connected to port........."+client.getRemoteSocketAddress());
	        client.close();
	      } catch (SocketTimeoutException s) {
	        System.out.println("Socket timed out!");

	        break;
	      } catch (IOException e) {
	        e.printStackTrace();
	        break;
	      }
	    }
	  }
	  public static void main(String[] args) {
	    try {
	      Thread t = new SocketGetSoTimeout1();
	      t.start();
	    } catch (IOException e) {
	      e.printStackTrace();
	    }
	  }
	}

ClientApplication:

import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;

public class ClientApplication {

	public static void main(String arg[]) throws UnknownHostException,IOException
	{
	Socket s=new Socket("127.0.0.1",1408);
	System.out.println("Connected on Port " + s.getPort() + "...");
	}
}

Output:

Example 2

ServerApplication:

import java.io.IOException;
import java.io.PrintStream;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.UnknownHostException;
import java.util.Scanner;

public class   SocketGetSoTimeout2 {
	public static void main(String[] args)throws IOException {
		// TODO Auto-generated method stub
		int num,temp;
		String s;
		ServerSocket s1=new ServerSocket(1408);
		s1.setSoTimeout(10000);
		Socket ss=s1.accept();
		Scanner sc=new Scanner(ss.getInputStream());
		s=ss.toString();
		num =sc.nextInt();
		temp=num*num;
		PrintStream p=new PrintStream(ss.getOutputStream());
		p.println(temp);
		p.println(ss.toString());
		System.out.println("ServerTimeout"+s1.getSoTimeout());
	}

}

ClientApplication:

import java.io.IOException;
import java.io.PrintStream;
import java.net.Socket;
import java.net.UnknownHostException;
import java.util.Scanner;

public class ClientA {

	public static void main(String arg[]) throws UnknownHostException,IOException
	{
	int n,tmp;
	String str;
	Scanner sc=new Scanner(System.in);
	Socket s=new Socket("127.0.0.1",1408);

	System.out.println("Enter any number");
	n=sc.nextInt();
	PrintStream p=new PrintStream(s.getOutputStream());
	p.println(n);
	tmp=sc1.nextInt();
	System.out.println("Square of given number is: "+tmp);
