Java ServerSocket getReuseAddress() method

The getReuseAddress() of java ServerSocket class is used to check whether SO REUSEADDR is enabled or not.

Syntax

Returns:

A boolean indicating whether or not SO REUSEADDR is enabled.

Throws:

SocketException - if there is an error in the underlying protocol, such as a TCP error.

Since:

1.4

Example 1

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.net.Socket;
import java.io.*;
public class GetReuseAddressMethod1{
 public static void main(String[] args) throws Exception {
		    String serverName = args[0];
		    int port = Integer.parseInt(args[1]);
		    try {
		      System.out.println("Connecting to " + serverName + " on port " + port);
		      Socket client = new Socket(serverName, port);
		      System.out.println("Local Socket Address "+client.getLocalSocketAddress());
		client.setReuseAddress(true);
		System.out.println(client.getReuseAddress());//using getReuseAddress()
		client.close();
		 } 
		catch (IOException e) {
		      e.printStackTrace();
		    }
		  }
		}

Output:

Java ServerSocket getReuseAddress() method

Example 2

import java.io.*;
import java.net.*;
public class GetReuseAddressMethod2{
	public static void main(String args[])
	{
		int port=1408;
		try
		{
		ServerSocket sock = new ServerSocket(port);
			sock.setReuseAddress(true);
			System.out.println("Server initialized on port " + port);
			System.out.println(" "+sock.getLocalSocketAddress());
			System.out.println(" "+sock.getReuseAddress());

			sock.getLocalPort();
			{
			while(true)
				sock.accept();
		
			}
		}
	catch (Exception e)
	{
		System.out.println("Some Error Occoured !!!"+e.getMessage());
	}
		}
}
