What is Java?
Java is a general-purpose programming language designed with the principle of “write once, run anywhere” (WORA). It achieves platform independence by using an intermediate representation called bytecode. When you compile a Java program, it’s translated into bytecode, which can run on any system with a Java Virtual Machine (JVM). This design allows developers to create applications that are compatible with multiple operating systems without the need to recompile the code.
Whether you are a complete beginner or an experienced programmer looking to expand your skill set, this comprehensive Java tutorial series will take you on a journey through the language, covering essential topics from the basics to more advanced concepts. Let’s explore what you can expect from each part of this tutorial series:
