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 ...

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.

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 ...

Instances are the foundation of object-oriented programming. Static methods are ones that aren't passed in any instance variables. As such, if you move static methods and static variables into a ...

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 ...

The class in this example only defines properties. It contains no explicitly defined Java constructors. When no explicitly defined constructors exist, Java's virtual machine makes object creation ...

Writing a Java application (see Android) that consumes a JSON API usually involves mapping the JSON objects to Java classes for use in the software. This is a tedious and repetitive task to say ...
