Examples and practices described in this page don't take advantage of improvements introduced in later releases.
However, most URL protocols allow you to read from and write to the connection. This section describes both functions. However, rather than getting an input stream directly from the URL, this program explicitly retrieves a URLConnection object and gets an input stream from the connection.
The connection is opened implicitly by calling getInputStream. The bold statements highlight the differences between this example and the previous:. The output from this program is identical to the output from the program that opens a stream directly from the URL. You can use either way to read from a URL. Again, if the program hangs or you see an error message, you may have to set the proxy host so that the program can find the Oracle server.

After you type in the required information and initiate the query by clicking a button, your Web browser writes the data to the URL over the network. At the other end the server receives the data, processes it, and then sends you a response, usually in the form of a new HTML page.

Get Grammar Girl's take on how to format URLs in text. Whether you should write out the full URL is also a matter of style. For example. Writing to a URLConnection. Many HTML pages contain forms For a Java program to interact with a server-side process it simply must be able to write to a URL.
The server recognizes the POST request and reads the data sent from the client. For a Java program to interact with a server-side process it simply must be able to write to a URL, thus providing data to the server. It can do this by following these steps:. Here is a small servlet named ReverseServlet or if you prefer a cgi-bin script.
You can use this servlet to test the following example program. The servlet running in a container reads from its InputStream, reverses the string, and writes it to its OutputStream. Let's examine the program and see how it works. First, the program processes its command-line arguments:. These statements ensure that the user provides two and only two command-line arguments to the program.
Then again, Sirius is all human creation, but Beats 1 is FREE. That certainly didn't work at Beats Music. The data needed for this calculator to function correctly is the investment amount, payment frequency, number of years for the contract, and the expected return percentage.

So don't let your nutritious meal go to waste and have a glass of juice with dinner.
The command-line arguments are the location of the ReverseServlet and the string that will be reversed. It may contain spaces or other non-alphanumeric characters.
These characters must be encoded because the string is processed on its way to the server. The URLEncoder class methods encode the characters. Next, the program creates the URL object, and sets the connection so that it can write to it:.
The source then creates an output How To Write Url In Html on the connection and opens an OutputStreamWriter on it:.
If the URL does support output, then this method returns an output stream that is connected to the input stream of the URL on the server side — the client's output is the server's input. This code writes to the output stream using the write method. So you can see that writing data to a URL is as easy as writing data to a stream.
The data written to the output stream on the client side is the input for the servlet on the server side. The servlet reads the information you write, performs a reverse operation on the string value, and then sends this back to you. You now need to read the string the server has sent back. The Reverse program does it like this:. If your ReverseServlet is located at http: The bold statements highlight the differences between this example and the previous: Connecting to a URL Next page:
