Types in Java

There are various kinds in Java that help with data organisation and storage. Primitive types that hold fundamental data directly include integers (int), floating-point numbers (float), characters (char), and boolean values (boolean). Also , Java has non-primitive types like classes, interfaces, arrays, and enums, which enable the creation and use of more complex and unique data structures in programmes.

The differences of primitive and non-primitive

Java primitive types are simple data types such as integers (int), characters (char), floating-point numbers (float), and boolean values (boolean) that are used to store values directly. They are not objects; they contain basic info.

However, complex data types in Java, such as classes, interfaces, arrays, and enums, are referred to as non-primitive types. Since they are pointers to objects, methods and other data can be stored in them. Non-primitive types can access methods and attributes and can be null, in contrast to primitive types.

OOP

OOP namely Object-Oriented Programming . It's a style of programming that groups code according to objects, which are just some of classes. Code that is reusable may be created because objects have methods and variables that interact with one another. OOP stresses ideas like encapsulation, inheritance, polymorphism, and abstraction to improve readability, flexibility, and maintenance of code.

4 Pillars of OOP
Four essential ideas are represented in object-oriented programming, or OOP. Encapsulation is the process of combining processes and data into objects to limit access and assure regulated interaction. Code reuse is encouraged by inheritance, which allows new classes to inherit traits from previous ones. Through method overloading and overriding, polymorphism allows objects to be viewed as instances of their parent class, enabling flexible coding. In order to produce simple, intelligible models, abstraction concentrates on the most important elements while hiding intricate implementations. These ideas work together to create the basis of OOP, which encourages modular, reusable, and well-organized software development.
