Welcome to Java Classes and Objects: Essence of Java
Programming notes! This document will cover the
following topics:
Methods in Class: Behavior of Objects
Methods in a class define the behavior of objects. They are
similar to functions in other programming languages.
Constructors: Automatic Execution on Object Creation
Constructors are special methods in a class that are
executed automatically when an object is created. They
have the same name as the class and are used to initialize
the object's instance variables.
Class Definition: Blueprint for Objects Creation
A class is a blueprint for objects. It defines the properties
and behavior of objects. A class can contain methods,
instance variables, and constructors.
Instance Variables: Representation and Usage
Instance variables are the properties of an object. They
are defined in a class and can be accessed and modified
by the class' methods.
this Keyword: Access to Local Class Variables
The this keyword is used to refer to the current object in
a method. It can be used to access local class variables or
methods.
Encapsulation: Class-specific Variables and Methods
Encapsulation is the concept of hiding the internal
implementation details of a class and only exposing a
public interface. It allows for class-specific variables and
methods to be hidden from outside access.
