basic class structure of a java program
What is the Structure of class in Java?
A class in Java defines the structure of objects by declaring variables and methods.
These variables and methods, when instantiated in an object, determine how it behaves and interacts with other objects.
The class doesn't consume any space until it's instantiated.What is the basic class in Java?
In Java, the class is a blueprint from which we can create an individual object.
Java provides a keyword named class by which we can declare a class.
Inside the class, we define class members and functions.
It is not possible to create Java programs without class.What is the basic Structure of a Java program?
Every Java program consists of a collection of classes--nothing else.
A class is a template for creating a particular form of object.
Each object created by the template contains the same members, each of which is either a field or a method.
A field is a ``container'' that holds a value.In Java, a class definition starts with the word "class" (possibly preceded by the word "public" or "private"), continues with the name of the class and the character "{" (a left brace or curly bracket), and ends with the character "}" (a right brace).
Inside the braces are definitions of methods and variables.
