Description
Java is one of the most well-known programming languages out there, primarily due to how adaptable and perfect it is. Java can be utilized for an extensive number of tasks, including programming improvement and versatile applications. Knowing Java opens a lot of doors for you as a developer.In this series of 5 courses, you'll build professional Java projects and be confident with your programming skills.Course 1:From installation to key features, this course will be your companion as you build robust and efficient applications with the latest features of Java 11. This tutorial will give you a head start in programming. It supplies enough material for you to start creating something with it right from the word go.Course 2:Next, you will be introduced to algorithms, big O notation, bubble, merge, quicksort, and other popular programming patterns. You'll also learn about data structures such as binary trees, hash tables, and graphs. The course progresses to advanced concepts, such as algorithm design paradigms and graph theory. By the end of the course, you will know how to correctly implement common algorithms and data structures within your applications.Course 3:This course takes a thought-leadership approach, gently introduces you to Functional Programming, and takes you all the way to becoming a master of the paradigm. You'll then learn how to work with higher-order functions, lambda functions, collections and more. You'll learn how to apply the best data structures and algorithms that optimize functions and also how to reuse and refactor functional blocks of code.Course 4:This course is a step-by-step guide to creating applications with Java 12 by applying reactive programming. You will get hands-on experience; each section will build on the previous one, so that you will be able to make your app responsive and reliable by implementing reactive principles with Java.Course 5:Multi-core processors are everywhere—from super-computers to mobile devices right in your pocket. That's why a modern developer must know how to leverage the power of multithreading.This course will teach you how to use parallelism and concurrency in Java. You will learn how to parallelize tasks and functions with the ForkJoin framework and Streams. You will also learn how to work with the very popular Reactive Streams recently introduced to Java. Furthermore, you will master concurrent collections and lower-level synchronization techniques with locks.
