1.Object-Oriented Programming(OOP:面向对象编程) 1.An object has a unique identity, states, and behaviors.属性与行为 2.Objects can interact with each other for computing tasks.对象之间的交互 用开车来类比 step1:declaration 1.Class: when programming in Java, we begin by declaring a program unit...
When you write code for objects at the root of the hierarchy, any objects created by a child class within the hierarchy have the same functions. Depending on the type of object, it may execute different behaviors.比如,鼠标的left_click动作,点击关闭按钮是关闭页面,点击文件是选中(Selected), 这...
Object-oriented Programming 面向对象编程 Object-oriented programming (OOP) is a programming paradigm that uses ” objects ” to design applications and computer programs. 面向对象编程(OOP)是一种编程范式,它能够使用“对象“来设计应用程序和计算机程序。 It utilizes several techniques from previously establis...

Object-oriented programming may be seen as a collection of cooperating objects, as opposed to a traditional view in which a program may be seen as a list of instructions to the computer. In OOP, each object is capable of receiving messages, processing data, and sending messages to other obje...

重要的是,我们在编程的时候一定要用object reference来指向object,然后通过object reference来控制这些objects。最为常用的是one reference point to one object,当然也可以使用多个references。 没有reference指向的object在编程的时候非常不推荐,很有可能就没有办法访问了,造成内存泄漏;或者因为没有指针指向他,被java garb...
Object-oriented programming allows procedures about objects to be created whose exact type is not known until runtime. For example, a screen cursor may change its shape from an arrow to a line depending on the program mode. The routine to move the cursor on screen in response to mouse movem...
In object-oriented programming, a bottom-up approach is followed. Programs consist of a collection of instructions telling the compiler what to do step-by-step, which makes the large codes difficult to maintain. Instead of a set of instructions, objects are created that combine both data and ...
