Object-oriented programming (OOP):

  • Java is an OOP language. This helps the code in Java to be reusable and easy to test, and to have a clean, elegant, and organized design.

Flaticon Icon


  • Java is "platform-independent", so it runs on all kinds of platforms. This means that Java can work regardless of the platform.

Secure and robust:

  • Java allows developers to create virus-free programs thanks to its several layers of security. Java also helps users achieve error-free programming.

➕ Java is also known for being:

  • easy to maintain because it can run on any system. There's no need to invest in specialized environments to execute Java programs.

  • multi-threading,which means that Java allows the execution of multiple threads at the same time to maximize resources.

  • scalable,which means that the software built with Java can support the physical growth of a system (i.e. increasing the memory of a system).
