Reading Data from the Internet

To read local file streams, a program has to specify the file's location, i.e. "c:\practice\training.html". The same procedure is valid for reading of the remote files: just open the stream over the network. Java has a class URL that will help you to connect to a remote computer on the Internet. At first, create an instance of the class URL: try{ URL xyz = new URL("http://www.xyz.com:80/training.html"); } catch(MalformedURLException e){ e.printStackTrace(); } The MalformedURLException could be thrown if a non-valid URL has been used, for example missed protocol if you forgot to sta...

TypeScript Generics

TypeScript supports parameterized types, also known as generics, which can be used in a variety of scenarios. For example, you can create a function that can take values of any type, but during its invocation, in a particular context, you can explicitly specify a concrete type. Take another example: an array can hold objects of any type, but you can specify which particular object types (for example, instances of Person) are allowed in an array.

Various events may happen to a running program: a user clicks on a button in a window, the Web browser decides to re-paint the window, and so on. I'm sure, you've tried to click on the buttons of the calculator from the lesson on Swing Basics, but these buttons were not ready to respond to your actions yet. This time, let's teach window components to react on such actions. Each window component can listen to and process a number of events, and your program has to register window components with Java classes called listeners. You should make components listen to only those events th... (more)
