    Generics


Flexibility of Generics

Generics allow programmers to create one method that can work with multiple data types. Instead of writing separate methods for each data type, a single generic method can perform the same operation universally. This improves flexibility, reduces code duplication, and makes programs easier to maintain and extend in the future.


Type Error Detection

Generics provide compile-time type checking, which ensures that type-related errors are detected before the program runs. This prevents incorrect data types from being used and reduces the chance of runtime errors such as ClassCastException. By identifying these mistakes during compilation, generics improve program reliability, reduce debugging effort, and enhance code safety. This makes the development process smoother and helps maintain the overall quality and stability of software applications.


Runtime Performance Efficiency 

All type-related operations in generics are handled at compile time, meaning no additional work is done during execution. This process, known as type erasure (specially in Java), ensures that generics programs run just at fast as non=generics ones.
    Since generics do not store type information at runtime, they introduce zero performance overhead. Developers benefit from both type safety and execution efficiency. Therefor, generics achieve a perfect balance between safety and speed, improving code reliability without sacrificing performance in any way.

Java Design Patterns

Java Design Patterns Java Design Patterns are reusable, well-tested solutions to common design problems in object-oriented programming. They act as templates that guide how to structure classes, create objects, and manage interactions in a clean and efficient way. Instead of reinventing solutions, developers follow these established patterns to write flexible, maintainable, and scalable Java applications. They also improve communication by giving developers a shared vocabulary. Overall, design patterns help produce high-quality, organized, and adaptable software. Design patterns in Java are generally grouped into three main categories, 1. Creational Design Patterns These patterns deal with object creation mechanisms, improving flexibility and reuse. Singleton    Ensures only one instance of a class exists, and provides a global access point. Factory Method  Defines an interface for creating objects, but lets subclasses decide which          ...

Application Programming Interface (API)

Application Programming Interface (API) What is Application Programming Interface ? Through an API, a program can ask another program for information or actions and get a response without having to understand the underlying workings of the other program. In the example for Application Programming Interface, a restaurant waiter is the best example. The reason for saying this is that the waiter position is similar to API. The waiter receives an order from you, the customer. Your request is communicated to the chef (the server) by the waiter (the API). After processing the request and preparing the food, the chef hands it to the waiter. It is returned to your table by the waiter (answer). In the same way, the API takes the request from the client and sends a request to the server and accordingly the response from the server is sent to the client by APL Why do We need APIs ? Building scalable, adaptable, and networked systems requires APIs. Developers depend on them for the following reaso...
