Object Interface Using interfaces (interface), you can specify which methods a class must implement, but you do not need to define the specific contents of those methods. Interfaces are defined by interface keywords, just like defining a standard class, but all of the methods defined are empty. All methods defined in an interface mu

nil. if an object's class does not implement an initializer, the Objective-C runtime invokes the initializer of the nearest ancestor instead. It means that two steps 1 are required to allocate memory 2 for initialization to create an object. 1. allocate memory. sent alloc orallocWithZone: message to the object's class. This is the common [Class alloc]. Or the uncommon [Class allocWithZone]. 2 initialization. You need to call the init Method for initi

Different from C ++, Java is a pure object-oriented language. Object-oriented has three main features: inheritance, encapsulation, and polymorpism ). This part contains a lot of content. 01 I will take an example to familiarize myself with the Java Class Object Construc

I encountered an interview question today to request that an object be allocated at the specified void * pmem in the memory so that the object can be stored at pmem. I am not doing this anymore. The record is as follows. By default, the new operator placement of objects is used to create an object in free memory. If y

Today, I found the java interview programming questions in the Forum and thought about it. I found that I forgot my original programming basics. Question: How many equals 2x8 in the most efficient way? Along with the targeted thinking, I thought of 2x8. Later I thought that this efficiency was definitely not the best

1. ObjectObjects are one of the basic concepts of object-oriented programming. You only need to look at this name and you will know it. In our familiar object-oriented languages, such as Java or C ++, there are similar object defi

The software development process has not changed much over the years. The main problems that need to be faced during the software development process are: the long development cycle makes it difficult to ensure the correctness of the program, difficult to maintain and so on have not been well solved, despite the emergence of object-oriented, framework design and other concepts and tools. The component

Good questions about object-oriented analysis and design. it may take some time for the younger brother to get in touch with object-oriented design. every time you design a new system, you will encounter problems about how to split and design objects, let's talk about it. Fo
