Vectors can be used to achieve an automatically growing array of objects.Java.util.vector provides a vector class (vector) to implement a function similar to a dynamic array. There is no concept of pointers in the Java language, but if you use

Class inheritance is statically defined at compile time and can be used directly, and class inheritance can easily change the implementation of the parent class. But class inheritance also has some shortcomings. First, because inheritance is defined
Shows a shallow copy: for non-basic data types, after clone, the result is two pointers pointing to the same memory space, so it is only a shallow copy, so if the operation on one object, the other content will also change, it is obviously
Functions of vectors:
1. can store any object
2. Cannot store basic types of data, such as 39, unless the data is wrapped in a parcel class
3. Its capacity can be automatically expanded according to demand
4. Increase the efficiency of the

Today, I read a book and saw 8.2 recursion problems. I tried the code on the book. I felt that there were still many bugs, so I wrote one myself. The main reason is that the Code in the book is only recursive for recursion, which is not good at
CodeReuse is the vast majority
ProgramWhat members expect is also one of OO's goals. To maximize code reuse, we should pay special attention to the following aspects.
Programming interfaces
"Interface programming" is
Object-Oriented design method: The basic idea of Java object-oriented programming is to solve problems by constructing and organizing objects. Objects are good, and any object can be considered an object, for example, a car is an object. The object
