Java provides a built Stack class that can be used to implement a stack. import java.util.Stack; class Main { public static void main(String[] args) { // create an object of Stack class Stack<String> animals= new Stack<>(); // push elements to top of stack animals.push("Dog"); animals.push("Horse"); animals.push("Cat"); System.out.println ...

In order to create a stack, we must import java.util.stackpackage and use the Stack() constructor of this class. The below example creates an empty Stack. Here E is the type of Object. Example: Output:
1. Adding Elements: In order to add an element to the stack, we can use the push() method. This push()operation place the element at the top of the stack. Output: 2. Accessing the Element: To retrieve or fetch the first element of the Stack or the element present at the top of the Stack, we can use peek()method. The element retrieved does not get d...
In Java, the Stack class is a subclass of the Vector class and represents a last-in-first-out (LIFO) stack of objects. It extends the Vector class to allow for easy implementation of the stack data structure. Here’s an example of how you can use the Stack class in Java: In this example, we first import the Stack class from the java.util package. We...
The Stack class in Java is a legacy class and inherits from Vector in Java. It is a thread-safe class and hence involves overhead when we do not need thread safety. It is recommended to use ArrayDequefor stack implementation as it is more efficient in a single-threaded environment. Output: One more reason to use Deque over Stack is Deque has the ab...

Learn how to use the Stack class in Java to create and manipulate a stack data structure. The Stack class provides methods such as push, pop, peek, and search to perform LIFO operations on the stack.
Feb 14, 2023 · Learn how to create a stack data structure in Java using an array and generics. See the code, examples, and illustrations of push, pop, top, and empty operations.
May 31, 2022 · Stack Implementation in Java. A stack is a linear data structure that follows the LIFO (Last–In, First–Out) principle. That means the objects can be inserted or removed only at one end of it, also called a top. The stack supports the following operations: push inserts an item at the top of the stack (i.e., above its current top element).
