Review in-depth understanding of Java object-oriented programming A class is an abstract concept in which an object is a concrete representation of a class and is a concrete concept. There is a class first, and then the object

Java: Object-oriented Programming 1. Class The class consists of three parts: Class Attribute: used to describe the attributes of the things abstracted by the class itself. Class Method: used to describe what this abstract thing can do Constructor: each class has at least one special method, which provides the init

Oo Thinking Often see a lot of people complain about the configuration of Java ee/j2ee too complex, cumbersome, not easy to learn, in fact, the so-called simple and easy to learn depends on whether you have OO thinking mode. Presentation layer interface form is usually some discrete data, that is, a single field data, through struts and other frameworks to provide actionform and tag library, these individual field data encapsulation and business lay

and set methods, you can invoke the properties and methods in the "partial" class. When new creates an object, it first allocates memory for object properties and initialization blocks, and performs default initialization. If there is a parent class, first allocate memory and perform initialization for the parent class object and initialization block. The initi

, when the method is finished after the second age out of the stack, but the second age changed the value and print, does not affect the first , the main method continues to print the output age (at this time the first one); The reference data type creates a stack frame (array) when using array, points to the memory space in the heap, and then produces a stack frame (array), which is passed by the first array (address). It also points to the memory space in the heap, the second within the method

:---------------Characteristics:The function name is the same as the class nameDo not define return value typesThere is no specific return value, and the object is definitely returned after creation.If the class does not have a constructor defined, the JVM allocates an empty construct.If the class defines a constructor, there is no empty construct.Role:Initializes the object.Attention:The characteristics of the default constructor.Multiple constructor
