Java Packages
Java packages are a fundamental language feature that organizes classes and interfaces into namespaces to prevent naming conflicts and improve code modularity. They provide a hierarchical structure for grouping related types, such as java.util for utility classes or com.example.myapp for application-specific code, and are essential for managing large-scale Java projects.
Developers should learn Java packages to structure code effectively, avoid class name collisions in collaborative environments, and adhere to Java's standard library conventions. They are crucial for building maintainable applications, enabling features like access control (e.g., package-private visibility) and facilitating the use of build tools like Maven or Gradle that rely on package organization.
