program to move the value to another computer must solve the problem. Question 2: The fifth chapter after the question Q: What is the purpose of the rewrite method? Workaround: The P121 in the book is interpreted as: When a subclass overrides a method that can be inherited, it can write a new method body exactly as it intended to reflect the unique behavior of the overriding method. Overrides are explained in the role of rewriting: The rewrit

I did not say no to play games, just hope you can at the right time

characteristics that have hierarchies and subclasses that inherit the domain and methods of the parent class. Four advantages: The reusability of the ① code ② can easily customize the domain and methods of the subclass ③ parent class to be used for subclasses. ④ makes designing applications easier.For an existing class called a superclass, a base class, or a parent class. The new class is called a subclass, a derived class, or a child class. In gener

After 3 weeks of Java class Learning, from the teacher's content, I still have a lot of problems, in doing the problem always feel will do, but do not come out, the understanding of the program is not thorough. We've been studying this week. The definition of a class consists of two parts: a declaration and a class body, which consists of two parts: one defining an instance field (or a member variable), and two being a method definition. The definition object includes the object's declaration an
