Are you looking to learn the latest techniques in Java functional programming? Look no further! Our comprehensive programming course covers everything you need to know, from the basics of functional programming and lambdas, to advanced topics like the Java functional interface package and java streams.
Java is a programming language that is designed to be object-oriented, which means that it uses a model of data and behavior that is organized around objects and their interactions. However, Java also supports functional programming, which is a programming paradigm that is based on the concept of functions. In functional programming, functions are first-class citizens, which means that they can be treated just like any other data type in the language. This allows for a more declarative style of programming, where the focus is on what needs to be done, rather than how it should be done.
In this course you will learn about:
- What is Java Functional Programming
- Pure Functions
- Lambdas
- Java Functional Interfaces: Function, Suppliers, Consummers Predicates
- Java Combinator Pattern
- Imperative vs Declarative
- Java Streams API: Map, Filter, Reduce, Flatmap, Min, Max
- Parallel streams
- How Streams Work
- Lots of Exercises
Who is the course for?
The course is for anyone looking to deepen their knowledge of Functional programming and its application in real-world scenarios. This comprehensive course doesn't just focus on learning syntax but also explores the special features that Java has to offer, such as lambda expressions, method references, and map operations.
Functional programming is useful to increase the performance, scalability, robustness, and maintainability of any Java application. It can be used to solve various problems such as developing multiple threads or handling remote communication with Java's Stream API
Whether you're a beginner developer or a professional looking to improve your coding skills, this course will show you the big picture of functional programming and give you the techniques to implement it in your code.
Why learn Java Functional Programming?
Java is a programming language that is designed to be object-oriented, which means that it uses a model of data and behaviour that is organized around objects and their interactions.
However, Java also supports functional programming, which is a programming paradigm that is based on the concept of functions. In functional programming, functions are first-class citizens, which means that they can be treated just like any other data type in the language.
This allows for a more declarative style of programming, where the focus is on what needs to be done, rather than how it should be done.
5 reasons why you should learn functional programming:
- Improved code reliability and predictability. In functional programming, functions are pure and don't have side effects, which makes it easier to reason about and predict the behavior of your code. This can lead to fewer bugs and more reliable software.
- Enhanced modularity and reusability. In functional programming, functions are first-class citizens, which means they can be treated like any other type of data. This makes it easier to write modular, reusable code that can be composed and combined in different ways.
- Better support for concurrent and parallel programming. In functional programming, there are no shared mutable state or side effects, which makes it easier to write concurrent and parallel code that can take advantage of multiple cores or processors. This can improve the performance and scalability of your applications.
- Increased productivity and efficiency. Because functional programming encourages a declarative and expressive coding style, it can make it easier and faster to write code that solves complex problems. This can lead to increased productivity and efficiency for developers.
- Many companies are starting to develop projects based on functional programming. This rumped-up demand creates some amazing job opportunities that are reflected in developer’s salaries, as seen in the graph below:
