Supports some or most object-oriented features (classes and instances, encapsulation, inheritance, polymorphism) A language can be called an object-based or object-oriented language. Java and C# are currently the two most popular object-oriented languages.

Object-oriented languages ​​can be classified as:

1. Object-based programming languages;

2. Object-oriented programming languages.

Object-oriented programming has the following advantages:

1. Easy to maintain

The structure designed using object-oriented thinking has high readability. Due to inheritance Even if the requirements change, the maintenance will only be on local modules, so maintenance is very convenient and low-cost.

2. Easy to expand

Through inheritance, we can greatly reduce redundant code and expand the use of existing code;

We can use standard modules (here A "standard" is an agreement that programmers make with each other) to build our programs without having to start from scratch. This can reduce software development time and improve production efficiency;

3. Modularity

Encapsulation can define the access level of the object's properties and methods, and expose secure interfaces to the outside through different access modifiers , to prevent internal data from being modified in unsafe circumstances. This can make the program more modular and facilitate later maintenance and modification.

At the same time, object-oriented languages ​​allow multiple instances of an object to exist at the same time without interfering with each other;

4. Modeling

Although object-oriented languages The objects in the object are not the same concept as the objects in real life, but in many cases, the concept of objects in real life can be abstracted and slightly modified for modeling, which greatly facilitates the modeling process. (But modeling directly using real-life objects can sometimes be counterproductive).
