Structural Design Pattern - Software Engineering

Structural Design Pattern - Software Engineering  👽

In the industry we have to use Design Patterns to develop systems. There are 3 types of design patterns.

  1. Creational Design Pattern - helps instantiate objects
  2. Structural Design Pattern - helps organize relationships between objects
  3. Behavioral Design Pattern - helps solve communication problems between objects
In this blog we will discuss about Structural Design Pattern.

Structural Design Patterns 

  • Structural design patterns focus on the composition of classes and objects to form larger structures while ensuring flexibility and maintainability. 
  • These patterns provide solutions to ease the design of relationships between entities, making systems easier to extend and change.

Key characteristics of structural design patterns : 

  • Flexibility : Allowing changes to a software system's structure without major modifications to its individual components.
  • Reusability : By defining relationships between entities, structural patterns promote code reuse.
  • Scalability : Enabling the system to scale by efficiently managing object interactions.

Common structural design patterns: 

  1. Adapter Design Pattern  : Converts one interface into another interface expected by clients.
  2. Bridge Design Pattern : Separates an idea from how it's implemented, allowing both to change independently.
  3. Composite Design Pattern : Allows individual objects and compositions of objects to be treated uniformly.
  4. Decorator Design Pattern : Adds new features to an object without changing its code.
  5. Facade Design Pattern : Offers an easy way to use a complex system.
  6. Flyweight Design Pattern : Saves memory by reusing shared parts of objects.
  7. Proxy Design Pattern : Uses a substitute to manage access, add features, or save costs.
                           A trick to remember Behavioral Design Patterns :

Benefits of structural design patterns: 

  • Simplify system architecture.
  • Enhance the flexibility of object composition.
  • Improve code maintainability and readability.
  • Support the adherence to SOLID principles, especially the "Open/Closed" principle.

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...
