Since Java 21, wrapper classes have played an increasingly sophisticated role in Java’s type system. Here’s everything you ...

In class-based object-oriented programming, a supertype is a class that another class descends from. In OOP-speak, we say the subclass inherits from the superclass.

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 ...

Before Object Oriented Programming ... To define an object, to define the data and to define its methods, you use a class. Let’s imagine you want to create a class to represent a bank account.

If you're not familiar with object-oriented programming, some of the concepts can be hard to understand, especially if you're a longtime procedural language programmer. Follow along as we take a ...

In making the transition from a structured language to an object-oriented language, a software engineer must understand the concept of data abstraction and encapsulation. This, I believe, is the ...

In object-oriented programming, methods are programmed procedures included as part of a class. Methods can be included in any object in a class, and any class can have more than one method. In an ...

Going over what’s included in [Andy]’s port reads just like a syllabus for an object-oriented programming class. Stacks, queues, and lists make the cut, as do strings and vectors.

In this class, we will examine fundamental objected-oriented analysis and design techniques and show how decisions made during analysis and design impact the implementation of software systems. This ...

This lesson starts a new segment about Object-Oriented Programming (OOP) — an important set of concepts critical to understanding any modern software, not just modern embedded software. As usual in ...
