Design patterns are meant to be a form of best practices as to how to develop object oriented code and found by trail and error in many cases. Additionally design patterns are supposed to provide a common platform for developers, so they can talk to one another based upon what they expect to occur. By…

Of the several patterns out there, the Java Singleton is one of Gangs of Four Design patterns. In many ways it is one of the simplest design patterns to implement, however it does come with some concerns. The basic idea is that there can be only one object of a given class, and by its…

In complex applications, we generally do not want to think about applications as containing all of the data, data access, user interface, and business logic into a single set of code. Now some applications will have more complicated layers, additional layers, or hybrid layers, but the basic idea is here. Little changes can be difficult…

We looked at Serializing a Single Object previously, but what if we need to serialize multiple objects, like an array? Serializing an Array Well, we can do that fairly easily as well. Java can take an array of objects, and serialize it. However, it will only work if you de-serialize it as an array. Consider…

As we mentioned in the What is Serialization post, we can use Serialization to move data into or out of a data stream. So let’s take a look at a simple class, and one that we would want to serialize. This is pretty simple, as you’ll see, we’re just going to add an interface to…

Java serialization is a mechanism to transform an object into a byte stream, and back again via Deserialization. This is important for anything which needs to be transmitted to another device/service such as writing to a file, across a network, etc. In order to do this, we need to implement the Serializable Interface. This provides a…
