Java this Keyword
The this keyword in Java refers to the current object in a method or constructor.The this keyword is often used to avoid confusion when class attributes have the same name as method or constructor parameters.
Java Classes/Objects
Java is an object-oriented programming language.Everything in Java is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake.A Class is like an object constructor, or a "blueprint" for creating objects.
OOP stands for Object-Oriented Programming.
Procedural programming is about writing procedures or methods that perform operations on the data, while object-oriented programming is about creating objects that contain both data and methods.OOP is ideal for building scalable, reusable, and maintainable code.
Object-oriented programming has several advantages over procedural programming:
- OOP provides a clear structure for the programs
- OOP helps to keep the Java code DRY "Don't Repeat Yourself", and makes the code easier to maintain, modify and debug
- OOP makes it possible to create full reusable applications with less code and shorter development time.
