[Java] Restrictions For Declaration Of Class In Java || Learn Java 2018
JAVA is a truly object oriented programming language. You can't even write main function without class. Hence, it is necessary to learn to declare a class in JAVA. In this video Mr. Vineet Agrawal will show you how to declare a class in JAVA.
After watching this video you will be able to-
- Declare a class in JAVA
- Choose correct name for the class in JAVA
- Explain the structure of a class
- Define class properties
- Define class methods
In this tutorial, we will discuss about classes and objects in object oriented programming language Java. We will learn the syntax of class declaration and dive deep into access modifiers in Java.
As the name suggests access modifiers in Java helps to restrict the scope of a class, constructor , variable , method or data member.
There are four types of access modifiers available in java:
Default – No keyword required
Private
Protected
Public
A private member is only accessible within the same class as it is declared.
A member with no access modifier is only accessible within classes in the same package.
A protected member is accessible within all classes in the same package and within subclasses in other packages.
A public member is accessible to all classes (unless it resides in a module that does not export the package it is declared in).
We will also discuss nested class in this tutorial
A nested class is a member of its enclosing class. Non-static nested classes (inner classes) have access to other members of the enclosing class, even if they are declared private. Static nested classes do not have access to other members of the enclosing class.
