Stacks
A stack is a fundamental data structure that operates on a Last In, First Out (LIFO) principle, meaning the last element added is the first one to be removed. Stacks are commonly used in programming for various applications, such as managing function calls, undo mechanisms in software, and parsing expressions. In Java, stacks are implemented through the Stack class in the java.util package, which provides methods for pushing and popping elements. Understanding stacks is essential for grasping more complex data structures and algorithms, making them a vital topic in computer science and programming.
