The shuffle() method in Java is used to randomly reorder the elements in a list. This method from the Java Collections framework is particularly useful in scenarios where randomness is required, such as in card games, shuffling playlists, or random sampling. In this article, we will explore the purpose of the shuffle() method in detail, provide code examples, and explain how it works.
Learn how to find the maximum or minimum element in a Java collection. This guide provides code examples and explains how to use built-in methods for arrays, lists, and other collections efficiently.
