Java
Java is a high-level, object-oriented programming language that is widely used for developing applications and software for various platforms. Java programs are made up of classes, which are the blueprint for creating objects.
Class :
A class is a template or a blueprint that defines the properties and methods of an object. An object is an instance of a class, which has its own set of properties and methods. When an object is created, it can communicate with other objects by calling their methods.
Methods:Methods are functions that are associated with objects and are used to perform specific tasks. They can take input parameters and return a value. Methods are declared inside a class and are called on objects of that class.Instance Variables:Instance variables are properties of an object, which hold values that are unique to each instance of the object. They are declared inside a class and are initialized when an object is created.Static variables:
Static variables are declared using the keyword "static" and are typically used to store values that are common to all instances of a class, such as a constant value or a count of the number of objects created.
Syntax:
The syntax of Java is based on the C++ programming language, and it follows a similar structure, including the use of braces and semicolons. The semantics of Java are designed to be platform-independent, which means that Java code can run on different operating systems and hardware platforms without modification.Overall, Java's object-oriented design, class-based structure, and platform independence make it a popular programming language for developing a wide range of applications, from mobile apps to enterprise software systems.
