What is Java? Overview of Java
Java is a high-level programming language used to write software for various platforms. When a programmer writes a Java application, the compiled code (known as bytecode) runs on operating systems (OS) including Windows, Linux, and Mac OS. Java syntax borrows from the syntax of the C and C++ programming languages.
The Java programming language was developed by James A. Gosling, a computer scientist, and his colleagues at Sun Microsystems from the Green Sun project in the early 1990s.
Why is Java Important?
As mentioned by Mytour earlier, Java is used to develop applications and web platforms, designed to enable developers to write code that can run on any computer, architecture, or platform.
According to information on the Java homepage, there are currently over 1 billion computers and over 3 billion mobile devices worldwide running Java.
Utilizing Java
Java is utilized to develop applications and platforms across various devices, including computers, laptops, game consoles, Blu-ray players, car navigation systems, medical monitoring devices, smartphones, etc. Additionally, Java plays a crucial role in network systems, particularly in data storage centers and Web-based data transfer systems.
Applet Development
In addition to application development, Java is also used to write small programs or programs embedded within webpages. These programs, known as applets, are used to display map information, weather updates, games, or other interactive tools on webpages.
Programming Practices
Java is an object-oriented and class-based programming language. The syntax of Java primarily borrows from the syntax of the C and C++ languages. The greatest advantage of Java is its ability to run code on almost any platform, operating system, or computer architecture, as long as the device has installed the Java Runtime Environment (JRE).
JRE may vary, depending on specific types of devices, but fundamentally, JRE runs on a virtual machine or an environment capable of translating code into an application or program.
Java versus JavaScript
Users often confuse Java and JavaScript because both are used to create tools and games that run on webpages. However, Java and JavaScript are two completely different languages. Java is more robust and can be used as the sole programming language for an application. JavaScript is a scripting language used to supplement additional features, such as Java applets on webpages.
What do you need to prepare to learn Java?
If you're just starting out with Java programming, what you need to prepare is to download and install the Java Development Kit (JDK - the toolkit for developing applications using the Java programming language).
