Java is a relatively easy programming language that is used in web applications, standalone software, or mobile applications. Given its nature, the most convenient way to excellence in this language is to learn java online. Specialists quickly took notice of this and developed hundreds of sites where aspiring Java programmers can perfect their skills or learn everything from the basics.
Before going through 5 of the best platforms to learn java programming online, let’s learn a bit about its history and what makes it so convenient.
Java programming language was designed over 20 years ago as a platform-independent language for your everyday electronics: washing machines, microwaves, coffee pots, and the like, but quickly became popular among software and web developers for its functionality and ease of use. in 2016, Java is used by over 9 million developers for Android Apps, web applications, software development, web design, and financial or scientific applications. It is run by more than 3 billion devices worldwide and offers a convenient way to merge smart design with high functionality.
Its evolution is easily observed when comparing older versions to the latest 1.8, but its key attributes remain unchanged:
- Simple and intuitive: it’s easy to learn, write, compile, or debug when compared to other programming languages.
- Object-oriented: coders can create reusable code and modular programs.
- Highly secure and resilient.
- Architecturally neutral: the processor architecture (32 or 64-bit) of the machine a code was compiled does not endanger its functionality on other computers.
- Portable – WORA (Write Once, Run Anywhere) concept.
- Highly performant and executable.
- Dynamic and interpreted.
- Multi-threaded: allows creating multitasking programs.
