What is Database Architecture

Database  Architecture  Database store a lot of critical information to access data quickly and security we need to select the correct architecture for efficient data for management client for the machine is the database architecture client  . Database management system architecture help user to get their into a request done file connecting with database . We choose the database architecture based on the following factures  1.Size of the database                                                                            2.Number of users                                                                      ...

What is Features of Java (OOP)

 The Features of Java OOP (Object-Oriented Programming) are the key principles that make Java a   features object-oriented language.


            

Classes:-A class is a user define data type date contain data member and member function .A class is a group of similar type object that same have properties common be haviour and common relationship

Objects:- Object is instance of a class or real time entity of a class In OOP program is divided into number of object. it is a variable of a class object is an instance of class. Syntax:- Class-name, Object- name 


Abstraction:-

The process of hiding is complex implementation in details and showing only the essential features to the user.

Abstraction means providing only the essential details to the outside world and hiding the internal details  


Encapsulation:-

The building of data attributes and the methods operate on that data within a single (a class).

Encapsulation is data hiding  by direct access to object's internal state and exposing it only through methods. This protects data integrity and allows for internal change without affecting external code.

 

Inheritance:-

The mechanism of deriving new class from an old class is called as inheritance acquires the properties and behaviors of another class 

It promotes code reusability and establishes an relationship between classes, forming a hierarchy


Polymorphism:-

The polymorphism ability of an object to take on many forms that means. In Java, this primarily manifests through

       .Method Overloading:- A  child class provide its own version of a method from the                            parent  class allowing it to change or extends the method functionally

        Method Overriding:- A class can have multiple methods with the same name but                                different parameters making the code more  flexible and readable

What is Constants, Variables, and Data Types

Image
                                          Constants   Constants in java refer to fixed values do not change during the execution of a program , Java support several types  of constants as illustrated. .Integer  Constants      An integer constant refer to a sequence of digits , There are three types integers .namely decimal imager octal integers and hexadecimals integers . Decimal integers consist of a set of thing preceded by an optional minus sign Valid of decimals integer constant  .Variables  A variable is an identifier that denotes a storage location seed to store a data value unlike constant that remain unchanged during the execution of a program , a variable may take different values at different times during the execution of the program ,we had used several variable for instance , we used variables length and breath to store the values o...
