Programming in the computer field has been key to the technological advancement of our world. Today everything is programmed and we can work, consume and download programs or applications thanks to the already famous and well-known programmers. Yes, those people who are behind our PCs making our lives more comfortable. In this post we want to emphasize the importance of programming since this profession is increasingly in demand by the labor market. Also, we will explain 3 simple tricks to learn to program in Java. And now the question may arise why learn to program in Java and not in another language. We explain it to you.
Why learn to program in Java
As we have commented at the beginning of this post, there is more and more demand in the programming sector and Java is a very good language for learn to program, since it is not strictly necessary to have any previous knowledge of the programming language, although if you do, much better. The language that most closely resembles it is C programming language, so if we have notions in this language, we will see that the syntax in Java is very similar to this one. To all this we must add, as you can imagine, that Java is a simple language, based on C, object oriented (OOP) and at the same time, it is one of the largest languages with the most professional opportunities in the sector today, since the operating system for Android mobile devices is programmed in Java, as well as being a multiplatform language and in which it can be programmed for the Web. Consider that companies such as banks such as “la Caixa” have their website programmed in Java. What do you think?
Despite all this, Java is not a panacea. There are alternatives with much better performance. An example of this is the programming language C++. This language is faster at the same time that it is the maximum competitor in Java. Still, C++ is more complex and obviously harder to learn. Another drawback of Java is that it is proprietary. Specifically, Java is owned by Oracle, which means that it is not a free programming language. Although, like all programming languages, Java has its pros and cons, we believe that it is the best language to learn to program and get started as a professional in the sector. That is why we will go on to explain 3 simple tricks to learn to program in Java. Go for it!
The 3 tricks to learn to program in Java
Once we have clarified why Java is one of the best languages to learn to program and get started as a professional in the sector, we are going to detail 3 simple tricks to learn to program in Java.
- Syntax: Before starting to program in Java, we could acquire some basic knowledge of programming in C since, as we have commented at the beginning, Java is based on C. This would help us to better understand the syntax rules that we must use and understand. Remember that in most programming languages the syntax is very, very similar.
- Object Oriented Programming (OOP): Java programming is object-oriented programming (OOP). If we want to program in this language, we must document ourselves well on the concept of this type of programming. Once we are clear about what it is, everything will be much easier for us to understand. We just need to open our minds to the world of programming and think more about how to write our programs in terms of objects, properties, and methods. It is a way of programming closer to how we would express things in real life than in other types of programming.
- Aim: Before we get “crazy” to type code, we must be clear about the objective of what we want to program. A simple recommendation that even the best programmers in the world use is to take a pencil and paper to make a sketch of the program that we want to develop. Seems obvious right? In programming, organization is essential. Spending time on it will make it easier for us in the future. Think about it.
First of all, like any language in which we want to program, we must install a couple of programs on our PC so that Java runs on it and thus be able to program in said language.
- JDK: The JDK (Java Development Kit) or Java Development Kit, is a software that we must download to our computer so that it offers us the development tools for the creation of programs in Java.
- Integrated Development Environment (IDE): An Integrated Development Environment or IDE (Integrated Development Environment) is the software in which we can write our code, edit it, execute it and compile it in the available emulator that we have installed in our IDE. For programming in Java, we recommend downloading the Eclipse IDE for Java Developers.
After this post, surely you already have a clearer idea of how to learn to program in Java. TRUE? Still, those 3 simple tricks work for any programming language. We just have to download the development kit and the IDE corresponding to the language we want to program.
And now that? Do you dare to learn to program in Java?
