What Can You Do With Java?

Even if you’ve never been interested in programming, chances are you’ve heard the name Java – and for a reason. This is one of the most popular programming languages ​​in the world: it was created in 1995, quickly gained popularity and has not lost it for many years. In the November 2019 TIOBE rankings, Java ranked first, and according to GitHub statistics, third, with Python second and JavaScript first.

Java is used everywhere: you can find it in almost all big companies, including Netflix, AliExpress, Google, Intel, eBay, TripAdvisor, and many others.

By the way, this language was named after one of the varieties of coffee.

What is Java?

Java is a strongly typed, multifunctional object-oriented language.

What does it mean?

With multifunctionality, everything is quite simple: Java is really almost a “magic pill” – on it you can develop desktop applications, applications for Android, do web development and much more.

Strong typing does not allow mixing different types in expressions and does not automatically perform implicit conversions. This adds complexity: you have to write some parts yourself, and you have less freedom, but in exchange for this you get reliability.

An object-oriented language is a language that follows an object-oriented programming model. There are classes and objects in it. Classes are data types and objects are class representatives. You create them yourself, give them names and assign them properties and operations that you can perform on them. It’s like a constructor that lets you build what you want. It is with this system of objects that Java is primarily programmed.

What can be written in Java

As we noted above, Java is used in many areas. They write on it:

  • Android applications – Java is practically the only language for them;
  • desktop applications;
  • industrial programs;
  • banking programs;
  • scientific programs;
  • programs for working with Big Data;
  • web application, web server, application server;
  • embedded systems – from small chips to special computers;
  • corporate software.

Java is most commonly found in web development and in Android applications, but it is also very popular in other areas.

Java pros and cons

All the qualities of Java, be it strong typing or object orientation, have their pros and cons, and Java itself has them as a language.


  • Independence – your code will run on any platform that supports Java.
  • Reliability is in no small part achieved through strong static typing.
  • Comparatively simple syntax.
  • Java is the main language for Android development.

Object Oriented Programming (OOP) brings many benefits too:

  1. parallel development;
  2. flexibility;
  3. the same classes can be used many times;
  4. the code is well organized and easier to maintain.


  • Low speed (compared to C and C ++).
  • Requires a lot of memory.
  • There is no support for low-level programming (Java is a high-level language). For example, it has no pointers.
  • Since 2019, upgrades for business and commercial use have become paid.
  • OOP takes experience, and planning a new program is time consuming.
  • Controversial moment
  • Automatic garbage collection: On the one hand, this is a benefit, but on the other hand, the developer cannot control the process, although sometimes it is important.


So Java is a popular multifunctional language.

It is quite reliable, fast, useful almost everywhere, and has an uncomplicated syntax compared to many other languages. Yes, there are languages ​​that are even simpler, but if you do not have a goal of choosing the lightest, then Java is a good middle option.

Java is a great choice for web development, Android app development, and if you want to try your hand at object-oriented programming. Before you start working with any programming language, you need to learn about the app development challenges that developers often face.
