Creational Design Pattern - Software Engineering

Creational Design Pattern - Software Engineering  👽

In the industry we have to use Design Patterns to develop systems. There are 3 types of design patterns. You can use below link to get an small idea about design patterns. https://miyurangika1223.blogspot.com/2024/09/design-patterns.html 

In this blog we can discuss about Creational Design Pattern.


Creational Design Patterns 

  • Creational design patterns provide various object creation mechanisms where objects are create in a manner suitable for a given situation 
  • It increases flexibility and reuse of existing code.

Some creational design patterns:

  1. Factory method design pattern
    • It defines a method to create objects and lets subclasses decide the exact type of object to create.
    • We use this pattern when we don't know in advance what type of object to create and subclasses might want to control object creation.
    • Example: creating different types of notifications like SMS and Email.
  2. Abstract factory design pattern
    • It creates groups of related objects (like buttons and checkboxes) that are meant to work together.
    • We use it to ensure that related objects are compatible.
    • Example: Buttons and checkboxes for different operating systems.
  3. Builder design pattern
    • It defines the steps for constructing a product.
    • It is particularly useful when the construction process of an object is complex.
    • Advantages: Separation of concerns, Complex object creation, Flexibility.
    • Example: create an example where we build a Car with different configurations like Engine, Seats, and GPS system.
  4. Prototype design pattern
    • It allows cloning of objects, ensuring that a new object can be created by copying an existing one.
    • Advantages: Performance optimization, Avoiding object creation overhead, Flexibility
    • Example: Cloning a object
  5. Singleton design pattern
    • It ensures that a class has only one instance and provides a global access point to that instance.
    • It's used when you want to make sure only one object of that class is created and you want to control how it is accessed.
    • Advantages: Controlled access to instance, Lazy initialization, Global state
                           A trick to remember Behavioral Design Patterns :

                            Funny Ants Build Perfect Sandwiches    
                              
                                     FABPS

Benefits of structural design patterns: 

  • Flexibility in object creation
  • Control over object creation
  • Simplify object creation logic
  • Separation of concerns
  • Easier object management
  • Cost efficiency

Sorting Algorithms - JAVA👽

Image
 Sorting Algorithms - JAVA👽  Sorting algorithms are used to arrange data into a specific pattern (ascending or descending).We mainly discuss 5 patterns in this blog.  We can use any of this methods to sort an array. Selection sort Insertion sort Bubble sort Merge sort Quick sort  Selection sort ... Selection sort is well perform for small arrays and doesn't require extra temporary storage.  It uses selection method. It is poor to deal with huge list of items. It simple and easy to implement. It's time complexity is O(n^2) and space complexity is O(1). Here is the basic code for selection sort. for (int i=0; i< array.length-1; i++){             int curruntMinimum = i;             for (int curruntItem=i+1; curruntItem<array.length;curruntItem++){                 if(array[curruntItem] < array[curruntMinimum]){         ...

Object Oriented Programming - JAVA- class boundary, variable types, modifiers, java main method

Image
Object Oriented Programming - JAVA👽 There are certain aspects of Object Oriented Programming. So when we use OOP we need to know about those elements. In this blog, Let's discuss about class, variables, modifiers and methods & main method . Class.... A class is a blueprint that defines common variables and methods for objects of a particular type. A class has a boundary. Inside this boundary we only have the class, constructor and main method. Even if a method is in the class, we cannot take it to the class boundary. Variables.... Variables   are used to store information to be referenced and manipulated in a computer program. There are two variable types. Static variable Non - static variable Static variable The easiest way to find static variable is to find out if there is a static key ward.      ex :         static int i ; These can be accessed anywhere within the class. It can be accessed even without creating an object. Non - ...

Object Oriented Programming - JAVA- Method Overriding

Image
Object Oriented Programming - JAVA👽 Sometimes we have to fetch the same method name more than once. It is not possible in the programming process. But we can use method override to solve that error. So, in this blog we will discuss Method Overriding. Method overriding ... In a method inherited from a super class to a subclass, the process of changing the body is called as method overriding. So, To overriding the classes should inherit with one class to another class. Ex:   class Monkey{   void climb(){   sout ("Monkey climbs with their legs on jumping");   }    }   class Man extends Monkey{   void climb(){   sout ("Man climbs with using ladder");   }   } Here, above the subclass is the method of the superclass, and above that is the method of the subclass. That means, according to the example code,  The method of Man class is at the top The method of Monkey class is next The Man class is below the method o...
