How do Java and JavaScript differ in their features and purposes of use?

Java and JavaScript are two different programming languages with different goals and features:

• Java is a general-purpose, object-oriented programming language compiled into bytecode, which runs on the Java Virtual Machine (JVM). It is used for developing server applications, mobile applications (Android), desktop programs, and large enterprise systems.

• JavaScript is an interpreted scripting language originally created to add interactivity to web pages. It runs in the browser but is also used on the server (Node.js). It is a dynamic language supporting functional and object-oriented styles.

Main differences:

• Java is statically typed, JavaScript is dynamically typed.
• Java is compiled, JavaScript is interpreted.
• Java is used for creating applications, JavaScript for web development and scripting.

Example of Java:

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, Java!");
    }
}

Example of JavaScript:

console.log("Hello, JavaScript!");
