Java is a versatile and powerful programming language that enables developers to create robust, high-performance applications. Java is platform-independent, meaning that it can be run on any operating system, and it is also capable of running on multiple devices. In addition, Java is one of the most secure programming languages, making it ideal for developing financial or other sensitive applications. Despite its many advantages, Java has been criticized for being a verbose language, meaning it takes more code to accomplish tasks than other languages. Nevertheless, Java remains a popular choice for application development due partly to its versatile nature and wide range of features.
What’s the Difference Between Scripting and Programming Languages?
When it comes to coding, there are two main types of languages: scripting and programming. Scripting languages are designed to automate tasks and are usually used in web development. On the other hand, programming languages are more powerful and can be used to create complex applications.
The main difference between these two languages is that scripting languages are interpreted while programming languages are compiled. This means scripting languages don’t need to be converted into machine code before they can be run, making them faster and easier to use. However, it also means that scripting languages are less powerful than programming languages. As a result, most software applications are written in programming languages.

What are the 3 Java platform components?
Java Virtual Machine
The Java Development Kit (JDK) is a software package that enables developers to create Java-based applications. It includes a compiler, a debugger, and an interpreter, as well as a set of libraries and other tools. The JDK is available for several different platforms, including Windows, Linux, and Mac OS X. While the JDK is not required to develop Java applications, it is generally recommended for most projects.
In addition, many IDEs (Integrated Development Environments) include the JDK as part of their default installation. The JDK can be an invaluable resource for developers who are just starting with Java. By providing everything needed to develop Java applications in one place, the JDK makes it possible to get started quickly and easily.
Java Virtual Machine (JVM)
The Java virtual machine is a vital part of the Java platform. It is the component that provides the portable execution environment in which Java bytecode can be run. The JVM specification defines the structure and behavior of a virtual machine that runs Java bytecode. A wide range of software platforms uses a Java virtual machine to enable the running of Java-based applications. Because each platform uses its underlying hardware architecture, a virtual machine removes the differences between these architectures, allowing a Java application to run on any platform with a suitable JVM implementation. This portability is one of the major reasons for the popularity of Java as a programming language. Without the Java virtual machine, Java would not be near as widely used as it is today.
Java Runtime Environment (JRE)
Java Runtime Environment (JRE) is the software that runs Java programs. It provides all the necessary resources to run a Java program on any operating system. JRE is platform-independent and comes bundled with the Java Development Kit (JDK). JDK contains tools and libraries to develop Java software. JRE only contains the files required to run a Java program.
The Java Runtime Environment is responsible for making sure that your Java program runs smoothly on any machine without you having to worry about platform dependencies or security concerns.
