Java supports object-oriented programming, along with other popular languages like Python and C++. This works particularly well for large team projects where states change often. Using OOP, programmers can create classes in order to iteratively reuse code, with the same set of “instructions” being sent to different objects, rather than coding each operation from scratch each time. Object-oriented programming focuses on objects made up of both data (fields) and code (properties or attributes). In this guide, we’ll look into both the theory and practice of object-oriented programming to help you write performant and error-free Java code. While these concepts are crucial for creating well-structured Java programs in the development phase, implementing crash reporting can also help you catch the errors your end-users encounter in the operation and maintenance phase of the software development life cycle. Java comes with specific code structures for each OOP concept, such as the extends keyword for the inheritance principle or the getter and setter methods for the encapsulation principle. There are seven core principles of object-oriented programming, as follows.

OOP concepts are intended to improve code readability and reusability by defining how to structure your Java program efficiently. Java is a class-based object-oriented programming (OOP) language built around the concept of objects.
