Java Basic




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 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.


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.
