Bruce Eckel’s Thinking in Java Contents | Prev | Next and return values Up until now, the term function has been used to describe a named subroutine. The term that is more commonly used in Java is method, as in “a way to do something.” If you want, you can continue thinking in terms of […]

Bruce Eckel’s Thinking in Java Contents | Prev | Next data types: class If everything is an object, what determines how a particular class of object looks and behaves? Put another way, what establishes the type of an object? You might expect there to be a keyword called “type” and that certainly would have made […]

Bruce Eckel’s Thinking in Java Contents | Prev | Next destroy an object In most programming languages, the concept of the lifetime of a variable occupies a significant portion of the programming effort. How long does the variable last? If you are supposed to destroy it, when should you? Confusion over variable lifetimes can lead […]

Bruce Eckel’s Thinking in Java Contents | Prev | Next all the objects When you create a handle, you want to connect it with a new object. You do so, in general, with the new keyword. new says, “Make me a new one of these objects.” So in the above example, you can say: String […]

Bruce Eckel’s Thinking in Java Contents | Prev | Next with handles Each programming language has its own means of manipulating data. Sometimes the programmer must constantly be aware of what type of manipulation is going on. Are you manipulating the object directly or are you dealing with some kind of indirect representation (a pointer […]

Bruce Eckel’s Thinking in Java Contents | Prev | Next If Java is, in fact, yet another computer programming language, you may question why it is so important and why it is being promoted as a revolutionary step in computer programming. The answer isn’t immediately obvious if you’re coming from a traditional programming perspective. Although […]

Bruce Eckel’s Thinking in Java Contents | Prev | Next and lifetimes Technically, OOP is just about abstract data typing, inheritance and polymorphism, but other issues can be at least as important. The remainder of this section will cover these issues. One of the most important factors is the way objects are created and destroyed. […]

Bruce Eckel’s Thinking in Java Contents | Prev | Next with polymorphism Inheritance usually ends up creating a family of classes, all based on the same uniform interface. We express this with an inverted tree diagram: [5] One of the most important things you do with such a family of classes is to treat an […]

Bruce Eckel’s Thinking in Java Contents | Prev | Next Java looks a lot like C++, and so naturally it would seem that C++ will be replaced by Java. But I’m starting to question this logic. For one thing, C++ still has some features that Java doesn’t, and although there have been a lot of […]

Selected material from each chapter represents a lesson, which is followed by a monitored exercise period so each student receives personal attention. The lectures and slides for the […]

By the time you read this, Sun will have released three major versions of […]
