Basic Theory: ----------------------------------------------------- Java internal class: the definition of an internal class is defined within another class. The reason is: 1. An internal class object can access the implementation of the object created for it, including private data. That is, an internal class instance is privileged to the instance of the class that contains it. 2. for other classes in the same package, the internal class can b

indexOf (String str) { return indexOf (str, 0); // There is a public synchronized int indexOf (String str, int fromIndex) method }StringBuilder does not have a synchronous lock on the method, so it is non-thread safe .3. StringBuilder and StringBuffer in commonStringBuilder and StringBuffer have public parent class Abstractstringbuilder ( abstract class ).One of the differences between an abstract class and an interface is that the public methods of some subclasses can be defined in

The second Summary of Java learning! -- In-depth analysis of child classes and parent classes. I hope you can provide more support! By analyzing code from the memory perspective, you can understand a language in essence! Child classes inherit from the parent class into two types: 1. Method inheritance: The parent class directly transfers its method to the subclas

The Inner class-----is the class in the other class1. Definition of inner class Define class as Class xxxx{...} Inside a class, you can ' Build Xxxx$xxxx class file at compile time for internal classes Inner class cannot have the same name as an external class 2, the use of internal classes Use this class in a class that encapsulates its class province, using the same method a

In addition to the inheritance relationship between objects and objects, there is also an association: including a pair of more than one or one pairs of many pairs of one and many pairs, because these relationships in the Kodo EJB implementation of the principle is basically similar, so this article mainly on a pair of related relations in depth, At the same time, through simple examples of analysis and practice in detail how to use the annotations provided in the Kodo EJB to define the associat

This is an essential read for all who write important server applications with DAO. "Odbc:architecture,performance,and Tuning", Author: Lambert, Colleen. This white paper provides a good overview of how ODBC works and describes perfor

When we generate unit test coverage reports for a project using Cobertura, we often have the following requirements: Requirements Description: Because a project has many interface definitions, constant definitions, exception class definitions, these classes do not require unit testing. And when we use Cobertura to generate test reports, if we do not exclude these classes, it will make the reported data is

of the base class or the version of a derived class. The base class dynamically binds the function execution by adding the keyword virtual before the declaration statement of its member functions. Non-static functions other than constructors can be virtual functions. The keyword virtual can only appear before the declaration statement inside the class, but cannot be used for Function Definition outside the class. If the base class calls a function as a virtual function, the function is implicit

Use of pseudo classes in css3, and use of pseudo classes in css3 Objectives: The use of the after pseudo class in css and the last-child pseudo class. And some attributes of css3. Process: When creating a navigation bar, you will often encounter an effect of adding a separator after each li. When the last element is reached, the delimiter will be removed. So how to use pure css to make such an effect is ve

Generally, you need to put the new class in the classes folder. This is better for porting. However, the folder cannot be directly specified when VS is directly created, so it took some time to create a script in the afternoon. First, use python to write the file creation function. The interface is simple: Project name and new class name. Because you want to create it in the cocos2d-x/projects folder ., The py file and the subsequent bat file should b

Iv. abstract classes and instances of itDelphi has a class called abstract class, you can not naïve directly create an instance for it, such asvar strlst:tstring;begin strlst:= tstring.create; Strlst.add (' I love China '); Strlst.free;end;This is wrong, because Tstring is an abstract class.So how do you construct an instance for such an abstract class? The answer is to use its non-abstract subclasses. We know that Tstring has a non-abstra

understanding of the dependency is that a class A used to another class B, and this use of the relationship is contingency, temporary, very weak, but the change of Class B will affect the Class A. For example, if someone wants to cross the river, they need to borrow a boat, and the relationship between the man and the ship is dependent. At the code level, for Class B as a parameter, Class A is used in a method. In UML class diagram design, a dependency relationship is represented by a dashed li

An abstract class Csolid is designed to contain two pure virtual functions for surface area and volume. Design derived classes Ccube, Cball, Ccylinder, respectively, representing cubes, spheres, and cylinders. In the main () function, define Csolid *p; (P is a pointer to the base class, and the base class is an abstract class). This P-pointer is required to be able to find the surface area and volume of a cube, sphere, and cylinder object.The main ()

Pointers are one of the most important features of C in contrast to other languages, and pointers are widely used in C + +, and we use pointers to achieve polymorphism. However, it is well known that the use of pointers must be careful, otherwise it is easy to cause memory leaks Leak. When we have several pointers pointing to the same object, it should be noted that when to release this object:(1) If the release is too early, then the other pointers still point to the memory, if you use it will
