Java.util Package
The `java.util` package in Java is a fundamental part of the Java Standard Library, providing a wide range of utility classes and interfaces for various common tasks in Java programming. It includes components such as the **Collections Framework**, which offers interfaces like List, Set, Queue, and Map along with their implementations, facilitating efficient storage and manipulation of collections. The package also encompasses utility classes for **date and time** operations, including Date, Calendar, and TimeZone, although these have been largely superseded by the java.time package introduced in Java 8. Additionally, `java.util` provides classes like **Random** for generating random numbers, **Scanner** for parsing input streams, and **Arrays** for working with arrays efficiently. Overall, the `java.util` package is an indispensable resource for Java developers, offering a rich set of tools for a wide variety of programming tasks.
