One of the major issues with software development is that you are not able to relate to the problem statement.
If you are a software developer and facing this issue too, OOP is just the right tool for you!
OOP is widely used in various languages such as C++, Python, Java, and many more. Out of which oops with java and oops in python are quite popular.
With OOP you will feel that you are dealing with real-time issues and entities when you are developing the software.
As you are surrounded by people who can perform vivid tasks for you in real life. In case of OOP these tasks are performed by objects. These objects can store various data, values, and knowledge to ensure that you are able to make these objects useful for different tasks.
Let’s discuss OOP and its meaning in an elaborated manner. The next section covers all the essential key points you need to know before using an OOP language.
OOP Programming Language- Key Points
Although, there are several features and advantages of OOP we have discussed the major benefits of using OOP in various languages:
OOP makes the code easier and it takes lesser time to execute
Applications developed with the help of OOP concepts can be reused for a variety of purposes and use.
With OOP, the overall structure of the code is easy to understand and edit if needed
Improves productivity of the program and the programmer
Also, there are various other benefits of OOP that help you develop a code appropriate for your idea.
Apart from these features, there are four major concepts on which OOP works. It is highly significant to consider all these concepts individually to clear the overall concept of OOP.
So, in the following section, the four pillars of OOP are discussed in detail.
Four Concepts Of OOP
After discussing the key features and benefits of object-oriented programming, now it’s time to discuss the four major concepts of the OOP system in various criteria.
Following concepts are widely used for oops in java, python, and in C++:
Inheritance
Well, inheritance is not a new word for you right? But wondering how it is applied for oops in java or oops in python? It holds a similar meaning yet technical approach.
Inheritance is a process or ability of a certain function through which it can take all Or some of the properties of an existing function.
Just like you inherit some or all of the genes from your parents, the new functions can inherit the properties of their parent function.
Inheritance allows you to reuse the code without typing the code again and again. Also, the reusability of code saves a lot of time for the developer.
Moreover, the class you defined earlier can be used and invoked again in a code without any errors. This reduces the overall length of the code and hence, the memory consumption.
For OOPs in java, inheritance has various categories. The java inheritance is of five types in general namely, multilevel, multiple, single, hierarchical, and hybrid.
You can define classes on various parameters and inherit their features in the different sections of the code.
Polymorphism
Polymorphism saves you from confusion and mixing types of classes. With this concept, you can easily use a certain class with exact use as of its parent class.
Let us simplify it for you, with polymorphism you can use a class in a way you used their parent class. This helps you to save time and prevents you from mixing up the types of classes.
Also, every subclass or usually called a child class will have its own functions. All the functions or methods of data evaluation for this child class remain as described by the developer.
For example, let’s say we create a class of flowers. The different flowers will lie in this category but will have their own functions (based on smell, colour, use, etc.) Individually.
This way, you will not mix the types of classes and consider different classes under one parent class type with polymorphism. This is highly used in the case of OOP in Python. Read full article...
