Java is one of the leading programming languages of all time. It is one of the most secure programming languages in the world. That is why it is the first choice to build banking applications. It is also used to create desktop applications. But with the most advanced technologies and the innovation of the most powerful programming language, Java, on its back foot. And the programmers and developers start moving to other programming languages instead of Java. There are lots of ways of how to learn Java.
But Java is getting back its momentum all because of its high security. Nowadays, Java is used to create a customized version of Hadoop for data science. That is why the demand for Java developers has gained a sudden boost. However, Java is one of the leading object-oriented programming languages. If you start with Java, you can easily learn most object-oriented programming languages in the future. Let’s have a look at some of the best ways to learn Java.
How to learn Java
Learn the Basics
If you want to be an expert in anything, then you have to master the basics. The same methodology applies to Java. If you want to be good in Java, you should start from the basics and master them. If you start learning the basics, you get something to start with your journey. Meanwhile, you can also practice the basics with small coding programming, e.g., print your name on the screen, create a calculator, etc.
It is obvious that if you don’t have any programming background, then you may find Java similar to a nightmare. But don’t lose your hope in the very first attempt; take your time to learn the basics and then move to the next step. Don’t be in a hurry to finish things off. If you are a beginner and a slow learner, you will spend more time covering basics than anyone else.
Practice makes a man perfect, the evergreen quote in history. Yes, it is true that if you want to have good command over anything, then you should practice. And it would be best if you practiced again and again until you get confident about the topic. If you avoid the practice, it will take more than a lifespan to master the Java concept.
The more you practice, the more you learn about the concepts. Java is easy to run, and you need not have the most powerful computer to run Java. All you need to have Java JDK installed on your computer to start learning Java. Along with that you should also use an IDE for Java development or you can use the command line for Java programming without installing IDE.
Set a goal and choose a language
Java has lots of uses and also has different versions for various tasks. Likewise, Java SE is used for online apps, Java EE is for desktop apps, and Java ME is used for cloud-based apps. Therefore it is essential to set your goal before getting started with Java. In this way, after covering the basics of Java, your next move would be to go with Java’s specified version.
It will save your time and help you stay focused to achieve your goals with Java. I would also like you to recommend that you should not stick with the single version of Java. It would help if you mastered a couple of Java version. It helps you to gain more opportunities in the world of programming. Likewise, for data science, you need to master the concepts of Java programming more than a single version of Java.
Set Your Algorithm Carefully
Algorithms are the set of instructions that tell the computer to perform specific tasks. There are millions of prebuilt algorithms in Java, and you can also use one of them within your program. When you cover some of the basic concepts to the intermediate concepts, it is time to test your skills by setting up your algorithm carefully.
It will have you to master the basic concepts of Java and boost up your confidence with Java. You should set up an algorithm because it helps you to test your skills. Once you are done with a working algorithm, you can master the advanced concepts with more confidence. Don’t ignore the algorithms because it plays a major role in every programming languages.
Trace Your Codes on Paper
It has been proven that we can have a good command over whatever we write from our hand; therefore, typing a code on a computer screen is not enough. You should also write the code in the notebook until you get a good command of the Java concepts. I would like you to recommend that you start writing the easy programs first and then move on to the medium one and finally the hardest one.
It would be best. If you also try to write the pre-written Java algorithms by your hands. Algorithms are usually complex than ordinary programming code. If you do it again and again, then you get a strong command over these algorithms. Keep in mind that the algorithms make the program more effective. You can also write a customized version of the algorithms.
Read Sources on Java Programming Regularly
There are thousands of online resources available online for free. You can have help from other experienced developers. These online sources also help the developers to stay updated with Java programming. You should check these sites at regular intervals. These resources not just help you to clear your doubts, but it also helps you to explore new ways to solve the same problem.
You can start joining the online Java forums and then start joining the coding communities over different social media networks and websites. These communities are full of experts and allow you to directly chat with the experts to clear your doubts in real-time. It is the most effective tips of how to learn Java.
Let’s Sum Up
Java has gained its momentum back and is still giving tough competition to modern language in terms of security. Thus if you want to get started with Java then you should go with it. Most of the programmers who have switched from Java to other modern languages are returning to Java because of its massive usage in data science.
Lots of medium to large data science enterprises are hiring Java developers with a decent salary hike. All the steps mentioned in this blog post on how to learn Java are quite useful for those who want to start learning Java. There can be a few more tips on learning Java, but these methods are well tested by our experts who know multiple programming languages.
