5 Technical Things You Need to Know Before Learning Java

 5 Technical Things You Need to Know Before Learning Java

Java is one of the most popular programming languages in the world. At the time, it is one of the most popular programming languages for developing applications on various platforms like mobile phones and personal computers.

Why Was Java Created?


The creator of this language, James Gosling from Sun Microsystems, wanted a platform on which developers could build applications for graphical operating systems and embedded systems. JAVA has worked on many platforms and sizes, from smartphones to servers and medical devices. Below are five technical things you need to know before learning java.

A Command Line


A command line is a powerful tool. It allows you to do what you want without worrying about the intricacies of windows or using a mouse. You can just type in commands and see what happens. The command line allows you to interact with a computer without opening an app or window. You can just type commands into a text box and get results back. Below are reasons why it is important to learn the command line.


It is so simple. You can do anything: make a website come up on your screen, add files to folders, run programs, search for files, and much more. It’s also super easy because there are only two things you need: commands and input/output.


The command line is powerful because it combines simple commands to do complex things. A command line is a tool that lets you automate repetitive tasks and is incredibly useful for people who want to do coding. For example, you can use the command line to create a program that will automatically save you from having to type in your password every time you log into your computer.


The command line is also tiny, but it doesn’t mean you can’t use it when there are bad connections or a spotty internet connection. It has only a few tools and commands, meaning you can use it even with a small amount of space on your computer.

It also means you won’t have to worry about loading up your whole computer just to do one thing. Plus, with the command line being so tiny and compact, it’s easy to move between different computers without worrying about losing anything important.

Object-Oriented Language


Object-oriented programming (OOP) is a programming paradigm that emphasizes code modularity, data abstraction, and inheritance. It is a popular language design style used in many languages, including C++ and Java. The idea behind object-oriented programming is to write the code in objects containing data and methods.


You can use these objects to create new classes with their behavior, which other objects can inherit. A class is a collection of related objects that share behavior. Classes are defined using classes and interfaces. The key benefits of object-oriented programming include:


Code reuse: Code written in object-oriented programming languages is reusable because it’s based on an object-oriented approach instead of procedural or functional approaches. Your code will be easier to maintain as you add new features and modify existing ones.


Modularity: Code written in an Object-Oriented Programming language has better modularity. You can interchange or remove a code to fit your needs.


Improved communication; Object-oriented programming is a great way to improve communication skills. With it, you can break down the objects into real-life entities. It makes it easier for users to understand the code and its concepts.

Try Coding in Another Language


You will enjoy coding in any language if you love programming or coding. Before learning Java, you can try coding in any other language and see how it goes. The best way to learn a new language is by trying it out. It’s not easy to learn a new language, but with a little practice and patience, it becomes easier.



Typing is one of the most important things you need to know before learning Java. If you don’t know how to type, it will be difficult to learn or even understand the language. It is because typing helps you focus on a problem, and it also helps you maintain your train of thought. It also means that if you can type lengthy information without errors, there is an increase in accuracy and speed.



Before learning Java, you should know some basic pre-algebra because programming is much like pre-algebra. Programming doesn’t require a lot of math but math skills—you just need to understand how things work. And, like pre-algebra, you can do the math in your head without writing anything down on paper.


You don’t need to know calculus or trigonometry to program in Java; all you need is some mental math skills that have been developed over time through playing games and solving problems with numbers.

Different Sources to Learn Java


If you’ve already decided that you want to learn Java but aren’t sure where to start, here are some tips for making your life easier.


You first need to know that there are many ways to learn how to succeed in an intro to Java course. Below are just a few:


  • Learn by doing: if you want hands-on experience with Java, try building something from scratch using the language itself as a reference point


  • Learn by reading: if you’d instead read about it and understand it better, read some books or tutorials on the subject


  • Learn by going online: if you want to get some help from other people who have learned Java before, search for forums or other social media pages dedicated specifically to learning about Java and asking questions


  • Learn by watching videos: If video tutorials are more your speed, there are plenty of YouTube channels covering everything from fundamental concepts like what an interface is up to advanced topics like writing complete applications in Java.


Essentially, most programming knowledge builds upon the basic pre-algebra concepts outlined above. If you understand these principles, you’re well on your way to a successful journey as a computer programmer. Always ask for help from people experienced in java when needed.
