Package: A package in Java is a way to organize related classes and interfaces. It provides a hierarchical structure for better organization and avoids naming conflicts.
Classpath: The classpath is an environment variable that tells the Java compiler and runtime where to find compiled classes and libraries needed by your program.
Static Import: Static import is a feature in Java that allows you to access static members (fields or methods) of a class directly without qualifying them with the class name. It simplifies code readability but should be used sparingly for clarity.
