Java is a computer programming language that is concurrent, class-based and object-oriented. The advantages of object oriented software development are shown below:

• Modular development of code, which leads to easy maintenance and modification.
• Reusability of code.
• Improved reliability and flexibility of code.
• Increased understanding of code.

Object-oriented programming contains many significant features, such as encapsulation, inheritance, polymorphism and abstraction. We analyze each feature separately in the following sections.

• Encapsulation
