However, when we start learning to code, we start with the C language and then move on to C++ or one of the many other programming languages. But today I am going to talk about the most popular programming language which is known as Java. The popularity of Java can be attributed to its versatility as it can be used to design customized applications that are light and fast and serve a variety of purposes. In most modern operating systems (OSs), a large body of reusable code is provided to simplify the programmer’s job. This code is typically provided as a set of dynamically loadable libraries that applications can call at runtime.
A Java Developer is a Computer Software Programmer who uses the Java Programming Language in the development of computer applications, web development, and other client and server-side requirements. This table compares various courses offered by Simplilearn, based on several key features and details.

The Java platform provides a security architecture[105] which is designed to allow the user to run untrusted bytecode in a “sandboxed” manner to protect against malicious or poorly written software.
Because the Java platform is not dependent on any specific operating system, applications cannot rely on any of the pre-existing OS libraries. Instead, the Java platform provides a comprehensive set of its own standard class libraries containing many of the same reusable functions commonly found in modern operating systems. For instance, the Swing library paints the user interface and handles the events itself, eliminating many subtle differences between how different platforms handle components.
