Java Socket bind() method25 Mar 2025 | 2 min read The bind() method of Java Socket class binds the socket to a local address. If the specified address is null, then the system will automatically pick up a port number and a valid local address to bind with the socket. SyntaxParameterThe parameter 'bindpoint' represents the SocketAddress to bind. ReturnNA ThrowsIOException - if the bind operation fails, or if the socket is already bound. IllegalArgumentException - if the bindpoint is a SocketAddress subclass not supported by this socket. SecurityException - if the security manager exists and its checkListen method doesn't allow the bind to the local port. Example 1Output: Inet address: null Port number: 1085 Example 2Output: Exception in thread "main" java.lang.IllegalArgumentException: port out of range:-1085 at java.net.InetSocketAddress.checkPort(InetSocketAddress.java:143) at java.net.InetSocketAddress. Example 3Output: Exception in thread "main" java.net.SocketException: Socket is closed at java.net.Socket.bind(Socket.java:625) at com.tpointtech.JavaSocketBindExample3.main(JavaSocketBindExample3.java:17) Next TopicJava Socket Class |
