Selection Criteria: Factors to decide for a Java course

Decided to take a Java course? Here are some criteria that may be useful when choosing which one to enrol in!

Application area

Many Java courses available on the market are indicated for programmers or have a more generalist aspect, only teaching the language without specific applications.

If your idea is just to learn how to program using Java, such courses are ideal. However, know that there is the option to specify to which area you want to direct the learning.

There are special Java courses for engineers, for application developers, for those who intend to make games, among others. With this, you can already have a certain specialisation by the time you finish!

There is a long distance between knowing the basics of Java and having full mastery of the language.

It is important to know if the course has the depth of teaching you need

Some courses just help you understand what is fundamental to start playing with the language, and are recommended for those who are curious about programming or want to have a basic knowledge in support of their programming. Others are much more complex.

You can also make your choice of course taking into account how important it is for you to have a complete mastery of Java.


For someone to be able to teach a certain subject, they need to master it completely. Never enrol in a course without knowing exactly with whom you will have class.

Our recommendation is to analyse the professor's curriculum, practical experiences with Java and theoretical experiences teaching. By observing all these factors, you will be able to conclude if the person is qualified to teach you the programming language.


Check if the methodology of the chosen course is compatible with your learning style. Are there many practical exercises? Are classes mostly in text or video? Is the course live or recorded?

Also, is the aspect more extensive, with lessons spread over a long period of time, intensive, compressed into a week or month, or free, allowing you to take control of the duration of learning?

Each person has an easier time with a different way, and following what's best for you makes the journey easier.


Knowing Java, the most widely used programming language in the world, is indispensable for professional programmers and very useful for those working in other areas. We recommend that you take a course on the subject, even if it is basic.

Java courses can be applied to a certain area, have only a simple level or be extensive and generalist, allowing total mastery of the language. You should choose what is more interesting for your formation and add this knowledge to your range!
