Java is an object-oriented strongly-typed programming language with C-like syntax that is closest to C ++ and C #. A special virtual machine is used to run Java applications; this virtual machine allows you to run applications on the operating system where it is installed, which ensures platform independence. Java has a huge number of libraries and frameworks that allow you to develop your own applications faster. Java developers are in demand in areas where they use projects with multi-user data processing and high security requirements. The Java programmer usually develops the architecture of the application, the business logic of the application, supports and maintains the project, and writes technical documentation.
