First. lets have a look at the package we need to import into our code. The java. net. package provides the Classes needed for implementing network applications. One. of the Classes is the Socket Class, which implements client sockets. We will use. this Class to connect to the localhost and scan through a range of ports. Now lets get started. The port scanner that we will develop will take two. The first argument is the start port, this is the port. The second argument is the stop port. We will. use a For loop to loop through the start and stop ports, each time we increment. Listing 1. 1 below is the complete code of the port scanner with line numbers.

On line 8 we have a For loop, this loop uses the start. Port. Range variable to. For loop. The loop increments until it reaches the stop. Port. Range. On line 9 we have a Try block, each time the For loop increments the Try block. The Try block creates an instance of the Socket Class. In the constructor of the. Socket instance Class, we supply the hostname or IP address and the port number. The following code on line 1. Socket Class with the. IP address. The variable i is the current port number. Socket Server. Sok new Socket1. If a connection is made on the localhost with the current port number the Try. Port in use message. If a connection could not be. Port not in. use message will be printed to the console. On line 1. 2 we close the Socket. We are now at the end of this article. I have very briefly introduced you to the. Socket class.
