Most modern languages support many of the data types we’ve looked at so far this term, including Stacks, Queues, Hash Maps/Dictionaries, and more. Many of these are supported within the language itself, often through a utility package, or something similar which can be imported, or from a third party library that can be imported. Which…
In order to understand network programming in Java, you need to understand couple of concepts first. The first of which, is what form of network connection are you going to be making. Typically, many modern apps use a client server model, and you make a request from a URL Process where a client uses a…
If you need to create a Thread in Java, and cannot extend the Thread class, often because you are extending another class, you can always implement Runnable. Notice, that just like where you extend the Thread class, you have to override the abstract method run. However, in this example, you need to create a Thread…
One of the two ways to use a thread in Java is to extend the Thread object. It can be done like the following. Of course this is only good if you are not extending another Class. You must override the run method, and you will need to call start() to start the thread and…
Threads, in general, allow a program to behave more efficiently by passing off parts of a process so that multiple items can be done simultaneously. With the advent and growth of multi-core processors which allow for many natural threads, this has been increased. Why do we need threads? Well simply put, there is always something…
Now that we’ve looked at some basic Layout Manager options, lets dive into building one. We’re going to work in the GUI that we’ve been building, first in Extending the JFrame Class, and then when we added JComboBoxes and JList to our project. Here we’re going to combine and use a couple of different layouts…
We’ve been using the null layout manager, in our previous examples of Java Swing. This is sometimes referenced as an absolute positioning layout, because we are required to control how the items are laid out and where. We do this with setBounds() or another method which allows us to define both the size of the…
Building upon the idea of the Local Storage, lets look at a simple example where we have an HTML form with fields of data we want to store, and how we can load that data in. Consider a situation where we need to store a person’s name, and then have it remember them for each…
