Classes, fields, methods, constructors, and objects are the building blocks of object-based Java applications. This Java tutorial teaches you how to declare classes, describe attributes via fields ...

One of the features that make Java so powerful, is its object-oriented structure. This means that Java uses classes and objects to create more scalable, modular, and organized code. This can be a ...

As you learned in my recent introduction to programming with classes and objects, you initialize an object via the code that you place in a class’s constructor. Consider Listing 7. Listing 7.

Object-oriented programming allows procedures about objects to be created whose exact type is not known until runtime. For example, a screen cursor may change its shape from an arrow to a line ...

Java deserialization example. Of course, Java object serialization is only half of the job. The other half is Java object deserializtion, which we accomplish with the FileInputStream and the ...

Java currently supports only two types of value: primitives and object references. Project Valhalla extends this by introducing inline classes which are a new form of type that exhibit some ...

Object-oriented systems are usually partitioned into layers of related responsibilities and only dependencies in one direction are allowed, from higher layers (more specific, less reusable) to lower ...
