What is Java?Java is a high-level multi-purpose programming language. According to the TIOBE index, it’s the most popular programming language in 2019. It works on almost every platform. Its motto "write once, run anywhere" means that Java code will work the same way across all platforms. On top of that, the Android OS was mostly developed in Java. Java is also popular for game development. It has powerful engines and libraries for developing 2D and 3D PC and Android games. Minecraft and Runescape are examples of very popular games programmed in Java.
Why Do People Learn Java?Java is a beginner-friendly programming language. It doesn’t just offer you a strong programming language to use, but it also teaches you how to think like a programmer.
New professional horizons for developers. Java is a general-purpose programming language suitable for many applications, like Android apps, video games, web applications, and so on. It also runs on many devices like cell phones, laptops, PCs, smart TVs, and others.
Java perspectives. Big tech companies like Google and Samsung are always in need of Java specialist programmers. Besides, they can work as freelance programmers in the huge Android app and gaming market.
Salaries in the Java industry. On average, a Java developer in the US gets paid $88K per year, according to glassdoor.com.
How to Start Learning Java?So you want to learn Java and don’t know where to start. You can start learning it right away. No prior programming knowledge is required. Here is some advice about the way to learn Java from scratch:
Setting GoalsYour goals should be SMART: specific, measurable, achievable, relevant, and timely. Don’t learn for the sake of learning; instead, work towards clear goals. In the beginning, concentrate on core concepts that will give you a solid foundation to build upon.
Planning Your EducationYou can get more out of your learning time by having a plan in mind. A good plan begins with learning the Java core concepts, moves on to intermediate additional concepts, and prepares you for the more advanced aspects of mastering Java.
Learning Process StagesIt’s a good strategy to approach learning Java in stages. First, learn the core elements of the language. Then, move on to intermediate concepts and skills. After that, you’ll be able to grasp the advanced element of the language easily.
Java Core:These are the most common skills that you need to have to start programming Java.
Java Syntax. Syntax is the rules of Java that you need to understand to write code that the compiler can read properly.
Basic concepts. For example, what are objects, classes, methods? On top of that, you need to know your 'if' statements and loops.
Object-oriented Programming (OOP). This is a programming paradigm where your code is centered around the idea of objects.
Algorithms. Algorithms are step-by-step instructions to perform a specific task. Some algorithms are more effective than others.
Unit Testing. A unit is the smallest testable part of your code.
Add-Ons:These are intermediate Java-related skills that you need to have a grip on before your master Java.
Git. This is a version control system, a very important tool when working with a team on a large project. These systems can keep track of changes made by the members of the team.
SQL. It stands for “Structured Query Language”, which is a specialized programming language for managing databases with a simple syntax.
Mastery:After grasping the core and intermediate concepts, it’s time to choose a path for mastering Java. Most Java programmers choose one of two paths:
Mobile technology. This is mainly related to programming for Android. It can be OS programming, game development, Android apps, etc.
Enterprise-level technology. This has to do with developing large server-side applications with specialized Java frameworks, such as Spring.
The Pareto PrincipleThe Pareto principle, also known as the 80/20 rule, is the principle that states that 80% of the effects come from only 20% of the efforts. For example, 80% of your coding projects will depend on the most common 20% of the concepts of Java. Similarly, you should spend 80% of your time practicing and 20% learning theory. It’s very important when developing or applying your learning plan.
Tools and Programming CommunitiesJava is a very powerful programming language; however, it’s not particularly hard to learn. The fastest way to learn Java is to start coding with Java. Learn the basics and apply them to as many problems as you can. The more time you put into coding, the better you’ll get at coding. After all, practice makes perfect. Don’t be afraid to make mistakes. You’ll learn better by trial and error. Even if you got the solution right from the first time, explore other solutions, and experiment with your code. mini-games section, where you can create your own version of popular games and publish them for others to play.
