Udemy Java Course Buyer’s Guide
What is Java?
Java is a high-level computer programming language originally developed by Sun Microsystems in 1991 and publicly released in 1995.
Sun Microsystems was later acquired by Oracle in the 2009/2010 financial year; and the development of Java as a general-purpose programming language continued, as Java-related technology became increasingly popular in the Android phone market alongside the responsive website niche where Java applications and servlets found increasing usage.
The current version was released by Oracle in 2020 and is Java 15.
Understanding the importance of Java
The 2 primary reasons Java is so important among programmers and software developers are its attributes of platform independence and neutrality towards computer architecture.
The latter means that Java can run in any computer regardless of the built-in processor (also called central processing unit[CPU]) that implements the instruction set architecture(ISA) which allows the operating system(OS) and hardware to interface with each other.
This means that it can run in Intel-based computers, embedded computer systems, Snapdragon processors of smart-phones, and system-on-a-chip(SoC) processors that run consumer computer devices built by Apple, Inc.

The benefits of platform independence
Platform independence means that Java-based applications can run on any computer regardless of the OS that has been installed.
This allows Java programs to run in Windows OS, Linux, Android OS, and iOS and Mac OS of Apple computers. Therefore, Java-based programs can run on any computer regardless of the processor design and the OS installed.
So what gives Java-based programs this broad range of compatibility?
Java Virtual Machine(JVM)
The answer is that the Java compiler (usually the Java Runtime Environment[JRE] or its superset Java Development Kit[JDK]) comes with a unique tool called Java Virtual Machine(JVM).
JVM is basically an abstract computing (or virtual) machine that allows for application virtualization – a form of high-level abstraction for programs written in a high-level programming language.
Abstract computing means that JVM works as an OS layer that is installed on top of the OS that runs the hardware of the computer, and all Java-based applications run on this JVM ‘OS’. JVM is OS-specific as there are JVMs for Windows OS, macOS, and Linux.
This also means that Java applications cannot run natively in computers that do not have JVM installed. This is the main dependency for Java applications.
Therefore, the Java code requires one to write it and then run it on any computer, popularly shortened as Write Once, Run Anywhere(WORA).
This gives Java applications their WORA cross-platform capability.

Object-oriented programming and modular programming
As a programming language, Java is designed as an object-oriented, class-based, and concurrent formal language that allows for both object-oriented programming and modular programming.
Regarding Java applications, they have very few implementation dependencies as JVM can run the Java bytecode(the format of compiled code) of the applications.
This makes Java applications quite stable and relatively immune to software aging issues caused by incompatibility problems with the OS running the computer hardware.
The main reasons for creating Java-based applications are the need to built simple, object-oriented applications that are robust and secure, and are portable, and architecture-neutral.
Likewise, these applications are dynamic and can be threaded, which allows for high-performance execution.
The syntax of Java language
The syntax of Java language borrows heavily from the syntax of C++ and C computer-programming languages. It also includes a few low-level programming language syntaxes.
For anyone planning to master Java, (s)he must learn the syntax. A good Java course must cover the basics of syntax, and then give the learner the skills to independently create, test, and deploy Java applications.
