Exploring Lambda Expressions in Java
Lambda expressions in Java are a powerful feature introduced in Java 8 that allow you to express instances of single-method interfaces (functional interfaces) more concisely. They provide a way to represent a piece of functionality as an object and pass it around your code. Lambda expressions enable you to treat functionality as a method argument or to create anonymous classes more compactly.
Functional interfaces in Java 8
A functional interface in Java is an interface that contains exactly one abstract method. Functional interfaces are key to enabling functional programming in Java, especially with the introduction of lambda expressions in Java 8. These interfaces can be implemented by any class or lambda expression that provides a concrete implementation of the single abstract method.
Streams in Java
In Java, streams provide a powerful way to process sequences of elements in a functional style. Streams were introduced in Java 8 as part of the java.util.stream package. They allow operations to be performed on collections (like lists, sets, etc.) in a more declarative manner, often enabling more readable and concise code.
Polymorphism
Polymorphism literally means “many forms.” In programming, it refers to using a single interface to interact with different types of objects, each with their own specific behavior
Collections
Explore collections concepts like arrays, stacks, queues, trees and graphs in depth.
Elastic Compute Cloud
EC2 provides resizable virtual servers (instances) in the cloud to run applications. Think of it as renting a computer from AWS that you can configure as needed.
