How Can You Learn Java Programming by Yourself?
Written by Shikha Mehta

Did you know that without any background knowledge in computer programming, you can still learn to do it by yourself? Yes, coding languages are not as tough as they seem. The best language you can start with is Java programming.

Java is one of the easiest languages to start from. This is not just because the codes are simple to understand, but also because the software highlights errors for you.

Even in some schools, when high school students are introduced to programming, they usually start with java code. Whether you have any background knowledge in programming or not, thanks to the internet, you can learn java by yourself now.

What is Java Programming?

Java is the no. #1 programming language used in the world by students and developers. This includes over 5 million students and 12 million developers. Released first in 1995 by James Gosling at Sun Microsystems (now acquired by Oracle), it has seen several updates and improvements.

It is used for developing applications, cloud servers and websites. Some of the reasons why developers prefer java over other programming languages are:

  • You can virtually run the code on another platform.
  • There are online compilers where you can practice programming.
  • Java is an efficient language when you want to program a customized app or site.
  • You can run java programs not only on computers, but also on mobile phones, microcontrollers and many other consumer devices.

Understanding Java Programs

Java for beginners is available in books, online tutorials and even on eb page articles. Here too, we’ll take a sneak-peek into how java programs look like. You start with a simple java program, followed by complicated ones. Following are some examples of what you’ll be learning.

Java Basic Programs

Usually, we start with basic arithmetic calculations to learn java. Or, it can also be as simple as writing a statement. Some of the things you’ll start with include:

  • Adding two numbers
  • Finding which number is greater or lesser
  • Display a box with a statement
  • Multiplying two numbers
  • Finding quotient and remainder
  • Calculating the power of a number

Prime Number Program in Java

This is commonly a program you start with when you learn how to write conditional statements in java. By conditional statements, we mean statements that involve the keywords “if”, “then” and “else”.

In this program, you simply check whether a given number is a prime number or not. For this, you’ll be writing statements to assign a value to a number, check if it is divisible by 2, check if it is divisible by any other number (if not 2) and then display the result. Basically, you need to explain the computer what a prime number is.

This is also a basic program, only that your coding expands from here.

Pattern Programs in Java

Once you learn how to write basic programs and conditional statements, you start moving towards writing longer codes. Pattern programs are programs where you learn how to draw various shapes through codes.

This means that your lines of coding may present an output that could look like any of the following:

Figure 1 is a star pattern, figure 2 is a numeric pattern and figure 3 is a character pattern. So, basically, in pattern programs, you’ll be learning how to write codes that can draw a shape.

Where to Practice Java Programming?

So, you have a basic idea of what you’ll be learning on Java and the books you can use to learn by yourself. Now, we come to the next step of learning – the platform on which you’ll be writing your java code.

Online Java Compiler

Just like python, java also has an online compiler (also known as an online java editor), where you can write and execute your programs. If you’re a complete beginner, you can start writing java programs online. There are plenty of websites where you can simply create an account and practice java programming.

Visual Studio

Visual Studio is an integrated development environment (IDE) developed by Microsoft for writing computer programs. It supports 36 different languages, which includes JavaScript, C, C++, C#, HTML, XML, CSS and many more. You have a separate software for Mac OS, while Visual Studio Code supports both Windows and Mac OS. Both free downloads and purchases are available.

The Java App

You can subscribe for the app of Java that has been licensed by Oracle. It is available for Windows, Mac and Linux operating systems. If you’re downloading Java for personal use, it is available for free. However, the commercial license may cost you a little bit.

What is Java Update?

Like any other technology, improvisations are made on programming languages too. The Java programming language has also gone through several upgrades, and so has the app. The latest version, as of 21st August 2020 is Java 8.0.

Java Update refers to the auto-update feature that you can enable in the Java app. These updates come to you free of cost with the Java app. All you have to do is turn on the notifications to check for updates as soon as they’re available. You can also check for the same manually. This helps you remain up to date with the current version of Java going on.

On a Final Note – Are You Ready to Learn Java Programming by Yourself?

There are plenty of programming languages out there, but Java is a no. #1 choice for both students and developers. According to TIOBE Index of August 2020 for the top 10 programming languages, Java has topped the list, followed by C and python.

All thanks to the easy-to-understand programming books and online education, learning programming has become easy for anyone. If java programming has been fascinating you, it’s not too late to start. What do you say, want to give it a shot?
