Java Socket getSendBufferSize() method

Last Updated : 17 Mar 2025

The getSendBufferSize () method of Java Socket class returns the buffer size(SO_SNDBUF) used by the platform for output on this socket.

Syntax

Parameter

Return

The getSendBufferSize () method returns the value of the SO_SNDBUF option of the specified Socket.

Throws

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

Example 1

import java.io.IOException;
import java.net.*;
public class JavaSocketGetSendBufferSizeExample1  {
    public static void main(String[] args) throws IOException {
        //calling the constructor of the socket class
        Socket socket = new Socket();
        //setting the send buffer size or SO_SNDBUF option with the specified value
        socket.setSendBufferSize(67);
        //getSendBufferSize() method returns the buffer size(SO_SNDBUF) used by the platform for output
        System.out.println("Send Buffer size: "+socket.getSendBufferSize());
    }
}

Output:

Send Buffer size: 67

Example 2

import java.io.IOException;
import java.net.*;
public class JavaSocketGetSendBufferSizeExample2  {
    public static void main(String[] args) throws IOException {
        Socket socket = new Socket();
        //getSendBufferSize() method returns the buffer size(SO_SNDBUF) used by the platform for output
        //by default the getSendBufferSize() method returns 65536
        System.out.println("Send Buffer size: "+socket.getSendBufferSize());
    }
}

Output:

Send Buffer size: 65536

Example 3

import java.io.IOException;
import java.net.*;
public class JavaSocketGetSendBufferSizeExample3  {
    public static void main(String[] args) throws IOException {
        //calling the constructor of the socket class
        Socket socket = new Socket();
        //setting the send buffer size or SO_SNDBUF option with the specified value
        //the buffer size should be greater than 0, else it will throw an error
        socket.setSendBufferSize(0);
        //getSendBufferSize() method returns the buffer size(SO_SNDBUF) used by the platform for output
        System.out.println("Send Buffer size: "+socket.getSendBufferSize());
    }
}

Output:

Exception in thread "main" java.lang.IllegalArgumentException: negative send size
	at java.net.Socket.setSendBufferSize(Socket.java:1193)
	at com.tpointtech.JavaSocketGetSendBufferSizeExample3.main(JavaSocketGetSendBufferSizeExample3.java:11)
