About Abhishek Kumar

I have spent the last 5 years developing custom software solutions for various businesses. I believe good software takes the commitment of clients, users and technology specialists. Communication is the key to getting results that benefits the business. Being fluent in over 15 programming languages I bring to the table a broad portfolio of technologies. Having developed software solutions totaling over a thousands of lines of code I have learned how important it is to manage stakeholders, to understand what they need and give them what they need.

Object Pool Design Pattern in Java with a real-world example

Object pool design pattern in Java works on the reusability concept of the object creation. This pattern is most efficient when it is expensive to create objects and can cause memory issues if multiple objects are created. It helps to improve the performance of the application.

Prototype Design Pattern in Java with a real-world example

The prototype design pattern works on the concept of cloning the object, which helps in the creation of complex objects in a very quick time. In other words, the Prototype copies the content and data of one object into a new unique object rather than creating a whole new object from scratch. In the creational design patterns, the prototype design [...]

Builder Design Pattern in Java with a real-world example

Builder Design Pattern solves the problem of constructing complex objects. In simple words, a situation when a class is having complex constructors or multiple numbers of parameters, it really becomes difficult to create objects in the same manner as the parameters are defined. Builder pattern solves the above problem through handling the situation by an object, rather than the multiple [...]

Abstract Factory Design Pattern in Java

Abstract Factory Design pattern comes under the creational patterns and it shows many similarities to the Factory Pattern. The abstract factory works as a factory of factories which generates other factories by providing an extra abstraction layer. The generated factory from an abstract factory pattern always generates the object as per the factory design pattern. In other words, We can [...]

Singleton Design Pattern in Java with a real-world example

Singleton works on the concept of one and only one instance of the object, which results in the global control of a resource. In simple words, the Singleton design pattern ensures that only one instance of the class will be created and that instance will have global access within the application. Singleton Design pattern is the most extensively used design [...]

Factory Design Pattern in Java with a real-world example

The Factory design pattern is a part of the creational design pattern. It works on the concept of Encapsulation by hiding the object's instantiation logic from the client. The factory Design pattern is the second most used design pattern in the creational patterns category, after the singleton pattern. The factory pattern is just opposite to the concept of the singleton [...]
