Gain the fundamental concepts of object-oriented programming with examples in Java in this book. This second edition comes with detailed coverage and enhanced discussion on fundamental topics such as inheritance, polymorphism, abstract classes, interface
6. Inheritance Inheritance is the mechanism that allows one class to acquire all the properties from another class by inheriting the class. We call the inheriting class a child class and the inherited class as the superclass or parent class. In Java, we do this by extending the parent clas...
Object inheritance is best applied to behavior, not data (see [Auer] for a lucid argument on this point). 对象继承最好应用于行为而非数据(请参见[Auer]对这个问题透彻的论证)。 www.ibm.com 2. Just look at the Java class hierarchy to see an elaborate set of object inheritance hierarchy. 仅...

A constructor can refer to another constructor in the same class or the immediate superclass using special forms of the this and super references. We’ll discuss the first case here, and return to that of the superclass constructor after we have talked more about subclassing and inheritance. ...
do it wisely and override it properly by taking care of mutable fields. It could be a daunting task if your class extends other class that in turn extends other class and so on. You will have to go all the way in the Object inheritance hierarchy to take care of the deep copy of all...
As you continue your journey in Java, consider exploring related concepts such as inheritance and encapsulation. These are fundamental principles of object-oriented programming that work hand-in-hand with constructors to create robust and flexible code. ...
