In this tutorial, we will learn how to use objects in Java. We will also see how to create classes, methods, variables, and constructors. Objects are used to store data and provide functionality. They are similar to other programming languages such as C++, Python, and JavaScript.
In object oriented programming, objects are used to store data. An object contains properties (data) and methods (functions). Methods are functions that operate on an object's properties.
There are three main features of OOPs. First, classes are collections of related objects. Second, objects contain data and behavior. Third, inheritance allows programmers to reuse code by creating subclasses.
Apart from these concepts, there are some other terms which are used in Object-Oriented design:
Here are some examples of OOPs in Java: • A class named Car has two attributes: color and make. • An object named car1 contains an attribute called color. • A subclass of car named sportsCar also has an attribute called color. Sports cars have red colors. • A method named printInfo() prints out the name of the car and its color.
OOPs is a powerful paradigm that allows us to build complex software systems by combining simple objects into more complex ones.
