Java Course Introduction
Like any programming language, the Java language has its own structure, syntax rules, and programming paradigm. The Java language’s programming paradigm is based on the concept of OOP, which the language’s features support.
The Java language is a C-language derivative, so its syntax rules look much like C’s. For example, code blocks are modularized into methods and delimited by braces ({ and }), and variables are declared before they are used.
Structurally, the Java language starts with packages. A package is the Java language’s namespace mechanism. Within packages are classes, and within classes are methods, variables, constants, and more. You learn about the parts of the Java language in this tutorial.
- The Java compiler
When you program for the Java platform, you write source code in .java files and then compile them. The compiler checks your code against the language’s syntax rules, then writes outbytecode in .class files. Bytecode is a set of instructions targeted to run on a Java virtual machine (JVM). In adding this level of abstraction, the Java compiler differs from other language compilers, which write out instructions suitable for the CPU chipset the program will run on. - The JVM
At runtime, the JVM reads and interprets .class files and executes the program’s instructions on the native hardware platform for which the JVM was written. The JVM interprets the bytecode just as a CPU would interpret assembly-language instructions. The difference is that the JVM is a piece of software written specifically for a particular platform. The JVM is the heart of the Java language’s “write-once, run-anywhere” principle. Your code can run on any chipset for which a suitable JVM implementation is available. JVMs are available for major platforms like Linux and Windows, and subsets of the Java language have been implemented in JVMs for mobile phones and hobbyist chips.
