1. What are Modules in Python? In Python, a module is a file containing Python code. It can be a Python file (with .py extension) or a compiled Python file (with .pyc extension). It contains functions, classes, and variables that can be used by other Python programs. Modules help us to organize our code into separate files, which can be used in other programs, making our code more reusable.

  1. Overview and History of Java Java is a general-purpose, object-oriented programming language that was developed by James Gosling and his team at Sun Microsystems in the mid-1990s. It is designed to be platform-independent, meaning that Java programs can run on any platform that has a Java Virtual Machine (JVM) installed. Java is widely used in enterprise applications, mobile applications, desktop applications, web applications, and games. Java is known for its simplicity, readability, and maintainability. It is a high-level language that abstracts away many low-level details, making it easy to learn and use. Java is also strongly-typed, which means that variables must be declared with a specific data type. 2. Features of Java Java is a feature-rich programming language that is known for its simplicity, portability, and security. Some of the key features of Java are: Object-Oriented Programming: Java is a pure object-oriented programming language, which means that everything i...
