In this tutorial, we will be looking at how to find the top and the bottom elements in a given stack using Java. When we look at the stack, it represents a linear dataset following the Last In, First Out (LIFO) principle, hence the elements are added and removed in the same place. We will further explore two approaches for finding a given stack's top and bottom elements, i.e. via iteration and recursion. Problem Statement We will be given a stack array of n elements and the task is to find the 1st and nth element of the stack without ... Read More
In this article, we will learn to initialize multiple variables to the same value in Java. What is a variable? A variable is a name given to a space reserved in the memory. Every variable has a type which specifies what kind of data it holds.

Removing even elements from the stack is useful in many real-world scenarios. For example, you can use this technique to filter the data from the stack. However, filtering logic can differ according to the scenario. In our case, we will remove even numbers and filter odd numbers. In other cases, you ... Read More
