The following are the advantages of Object ORIENTED Programming languages:

• Instead of needing to start writing code from scratch, we can build programs from standard functioning modules that communicate with one another, which saves time and increases productivity. The OOP language allows us to divide the PROGRAM down into bite-sized problems that can be solved quickly (one object at a time).
• Object-Oriented Programming languages have proven to increase programmer efficiency, improve software quality, and reduce maintenance costs.
• It is FEASIBLE for several instances of a class to coexist without interfering with each other. This allows for parallel development.
• It is relatively simple to divide a project's work into objects.
• We can minimise duplicate code and increase the use of existing classes by using inheritance.
• The data concealing principle helps programmers in developing secure programs.
• More information about the model in an implementable form can be captured by using the data-centred design technique.

The following are the disadvantages of Object-Oriented Programming languages:

• The length of programs written in the OOP language is significantly greater than that of programs written in the procedural technique. As the program grows in SIZE, it takes longer to execute, resulting in slower program execution. That can make it be an inefficient choice when there are technical limitations involved due to the size that it can end up being. Because of the duplication involved, the first-time coding can be more extensive than other options as well.
• Because using OOP is a little challenging, programmers must have excellent design and programming skills, as well as adequate planning.
• It takes some time to become used to OOPs. For some PEOPLE, the thinking process involved with object-oriented programming is not natural.
