Java reflection Technology, Java is the difficulty, but also the evolution of the programmer must play the small monster, here according to the Java API to study the Java reflection technology.Class Fields MethodsPlease recall the definition of Java

Object Type ConversionsIt is divided into upward transformation and downward transformation (forced object transformation). an upward transformation is the process by which a child object transforms into a parent object, such as a cat class to an

1. Process-oriented and object-oriented 1.1 process orientedProcess-oriented program design is the core of process (pipeline thinking), the process is to solve the problem of the steps, process-oriented design is like a well-designed pipeline,

Java reflection mechanism: in the running state, for any class, you can know all the properties and methods of this class, for any one object can be called to any of its methods and properties; This dynamically acquired information and the ability

In the release version of ExtJS4, a new class model (model Class) was added to the data package. This class is somewhat similar to the record in extjs3.x, but the new model is more powerful than the record class, and we'll discuss it together.

class variable : shape as static int A; As the name implies, a class variable can be understood as a variable of a class, and a class variable is allocated a memory space when the class is loaded, unlike an instance variable (int A; ), an instance

In Java, you can define member variables and methods within a class, and you can define classes within the class. This class is defined within the class as an inner class. The inner class is called the outer class. There is a separate. class file

V: Represents an operation that acts on elements in an object's structure. It allows you to define new actions that act on these elements without changing the class of each element. The visitor pattern is suitable for systems with relatively stable
