Do you want to learn Java but don’t have much time to invest? Buckle up and know the top Java online courses to upskills.

It is easy to jam up online courses and learn new programming languages in the present era. However, it is essential to determine where to start from, which programming language to opt for, and how to start your career in the respective field.

As per Statista, Java is the fifth most used programming language (35.35%) among developers. It makes developers take courses and certification programs to upskill themselves and learn the Java programming language.

But before deep-diving into the courses, let us cover up the basics of Java.

What is a Java programming language?

Java is a computing platform, class-based, high-level, and object-oriented programming language. It is also famous as a “Write Once, Run Anywhere” programming language similar to C++ and C syntax. The programming language is easy to learn, simple, robust, secure, fast, and reliable for game consoles, data centers, laptop applications, scientific supercomputers, etc.

It helps the developer run the application efficiently with libraries, computers, and execution engines. The multi-platform programming language works as a computing platform that helps develop the projects. The developers can use Java programming language for:

  • Big Data Analytics

  • Mobile Java Applications
  • Server-Side Technologies like GlassFish, JBoss, and Apache
  • Hardware Devices
  • Scientific Computing Application
  • Create Enterprise Software

Java is considered an easy-to-use and platform-independent programming language. It is used to create a distributed environment and facilitates distributed computing. Several components of the Java programming language make it easy to write human-readable source code. Java components include Java Development Kit (JDK), Java Virtual Machine (JVM), and Java Runtime Environment (JRE).

Java programming language can be an ideal choice for developers who can help develop any application or software. It comes with several benefits such as:

  • A large community that offers tons of resources to learn from.
  • It is an open-source programming language with a rich API and a comprehensive set of tools.
