What Is Java?
Java is a high-level object-oriented programming language with one special characteristic — it is platform independent. Meaning, it can be written once and run on any operating system, from Android to Windows and MacOS.
Instead of compiling directly to machine code, it compiles to Java Bytecode, an intermediary step between pure written Java and machine code. To run the Java Bytecode, a Java Virtual Machine (JVM) for a specific operating system needs to be installed. The JVM interprets the Java Bytecode to produce machine code to be run by the operating system.Due to Java’s versatility, it has become the third-most popular language according to the TIOBE index. Additionally, Java is simpler than languages like C and C++ which makes it easier to learn for beginners. According to glassdoor, the estimated total pay for a Java developer is $110,713 per year in the United States. So there’s a lot of demand for Java developers!
