How to learn Java

Java is one of the most widely used programming languages for developers in the world. If you learn to code in Java, you will have access to a wide range of opportunities.

Java is a versatile and widely used supported programming language that is widely used in everything from software development to mobile application development. Indeed, as of 2020, 95% of the smartphone market share was occupied by Android, and Android was written using Java.

But how do you learn to program in Java? We will solve this question today. We will break down our top tips on how you can start your Java journey. We'll also give you a list of effective recommendations on topics you can explore. After reading this article, you will have a clear roadmap to guide you through learning Java.


Is it difficult to learn Java?

Depending on how much experience you have, learning Java can be difficult. You will face many challenges along the way, but none will be overcome. If you have some prior experience of programming, you will find Java easy to learn.

Programming is a complex skill, for which you have to think very carefully about the instructions you want to give to the computer. For all their shiny sophistication, computers really perform simple steps over and over again.

It doesn’t seem like it would be hard to break the problem down into smaller steps, but it could. Like anything else, if you have some relevant knowledge about programming, you will probably find Java easier to learn.


How long does it take to learn Java?

With the right amount of practice and dedication, you will be able to learn the basics of Java in about three months. Expect to spend at least a year getting fully acquainted with the language.

Of course, this estimate depends on how long it takes you to learn Java. If you practice a few hours a day, learning Java in the middle of three months is a good guess.

Those who are admitted to the coding course can learn quickly depending on the speed of the course. Obviously, anyone who studies part-time or full-time will learn faster than they do in their spare time.


What is Java used for?

Java is a general-purpose language. This means that there is a range of potential uses. Java is commonly used in enterprise settings such as the financial industry. It is also used to develop applications for Android devices.

Since the Android operating system was created using Java, you will find millions of mobile applications around the world using Java.

Java is widely used as a back-end server in web development. This is because Java has a framework like Spring and Strut, which was designed to facilitate back-end web development.

Many modern-day desktop applications were written in Java. For example, video games were written using Minecraft Java. There are plenty of frameworks to extend the Java function for desktop applications.


Learn the basics of Java.

One mistake that many new students make is to move on to the first step in learning a programming language. That's a problem. Ignoring the basics may mean that you lack the knowledge that you need to explore the more advanced ones.

You can learn the basics of Java through a structured online Java course, book, or Java tutorial.

Java programming includes a wide range of language concepts and even expert Java developers are still learning how to make the best use of language and how to improve it further. That said, there are some important things you should master at the beginning of your journey. Let's explore these ones by one.


3 websites to learn Java for free

Resources for learning Java code online

In this article, I am going to share with you a few websites that will help you learn Java for free.

The first site works well for most Java programmers, but can be solved in any language there. The second site is language independent because it does not ask you to code online, but simply tests your answers with random input data.

1. Udemi

It is one of the most popular websites for learning Java and other programming languages online. It offers both free and paid courses, but the good thing is that you have a lot of choices and it is relatively cheap compared to any other website in the world.

It has lots of free courses in both Java and several programming languages, such as Java tutorials for full beginners, a total of 768,857 students were admitted to this course and it is one of the best free Java courses available online.

You can find many courses for learning Java, such as the Practice Java by Building Project, which is another free course for programmers to get started with Java.


2. CodeAbbey

The next site I am going to share with you is CodeAb. When I came across CodeAbbey, I really liked their question set because it was designed for complete newcomers.

It’s not simple or trivial and provides some decent practice for the 1st timer. Such questions you can hope from in this site:

  • Maximum array
  • Vowel number
  • The weighted sum of the digits
  • Body Mass Index (BMI)
  • The sum of the numbers
  • The middle of the three
  • Newman's random generator
  • Array checksum
  • Modulo and time difference
  • The average of an array
  • Array counter
  • Binary Search
  • Dice rolling

Once you start solving these programs, your programming logic will improve and you will learn how to apply knowledge of operators, data structures, and algorithms to solve a problem.

Slowly, you will learn how to obtainment a problem. Once you solve the beginner's problem, you can start with the middle and some difficult things to test your knowledge and gain some confidence.

Remember, it's the problem-solving skills that make you a good programmer-not just knowing the syntax of a programming language, such as C or C ++. Once you learn how to code or know how to program, you can easily solve the same problem in any programming language.

If you like books, you can buy a book to learn how to program, Head First Programming, which teaches you how to write and write a program code using Python.


3. CodeAcademy

One of the most popular websites that I used to learn JavaScript is CodeAcademy. Now, this is a free course for learning Java. This is one of the best, interactive websites for learning any language.

The CodeAcademy site provides an online IDE or Java editor where you can test not only the code but also run and debug your program.

The course is not available like PluralSite and Udemi, but it is free, and it is still a good resource for beginners.


Wrapping Up

Java is an excellent programming language for learning, whether you are new to programming or you are already an experienced programmer.

At the beginning of your journey, you should focus on mastering the basics: syntax, conditional, loop, debugging, and much more. Once you are familiar with the basic concepts of Java, you can start working on any project.

The benefits of learning Java are obvious. You will learn a new skill that can help you start a career in technology. You can use Java to solve the problems you have with the code. With the advice we have given in this guide, you are ready to start the journey of how to learn code in Java.
