The runtime systems for Java include a variety of safety features, such as runtime checking, static type-checking at compile time, etc. Inspired by C and C++, some of Java’s core OOP features include abstraction, encapsulation, inheritance, and polymorphism. Java is an object-oriented programming language. JRE (Java Runtime Environment) is also compatible with Operating systems such as Linux, macOS, and Windows.
These codes are executed on any system that runs a JVM. It then runs on the Java Virtual Machine. It is compiled into an intermediate format (also known as bytecode).
Hence it's platform independent (Writing Once, Run Anywhere). Airbnb, Uber, eBay, Spotify, Intel, Pinterest, Groupon, Infosys, Wipro, Symantec, TCS, Flipkart, and TripAdvisor, to mention a few, all use Java. Despite the fact that Java is a relatively new programming language (it was introduced in the early 1990s), it has carved out a distinct niche in the Information Technology sector.
