Since Java is strongly typed, you will often need to convert one type to another. The Java Language Specifications states that there are 13 such conversions possible. Here I will focus on two of these, widening and narrowing type conversions. While some type conversions need to be deliberately stated, sometimes…

After last weeks blog post, What is a Stack and how to Create one in Java, I figured it would be nice to give a practical example of using a stack in Java. Reverse Polish Notation (also known as Postfix Notation) is a different way to write mathematical expressions. Normally…

A stack, also known as LIFO (last in, first out), is a linear data structure with two main operations — push and pop. Items are added to the top of the stack, and items are removed from the top of the stack. The name ‘stack’ is very self explanatory, think…

Installing GitHub CLI 1.0 (beta) MacOS homebrew: brew install gh macPorts: sudo port install gh Windows scoop: scoop bucket add github-gh https://github.com/cli/scoop-gh.git scoop…

Usually forms are controlled in React. Using a controlled form gives you a high level of abstraction, easier testing, a single source of truth and more benefits over standard uncontrolled forms. Using a standard React controlled form however, has two major downfalls — lots of code and a re-render on…

When learning React, you will be introduced to the tool React.Component.setState() and instructed to never update the state property directly. In any programming language, if you are provided an accessor method (a getter or a setter), it’s safe to assume that you shouldn’t access the variable directly. …

Binary Numbers from a Decimal Perspective Decimal numbers have a base of 10, meaning that any decimal number can be represented as the sum of powers of 10. And in summation form:

Linked lists are the foundation of other data structures and can be used to create stacks, queues, and more. They can be very efficient when used correctly and can also be inefficient when used incorrectly. Random access is very expensive for a Linked List. A linked list is a collection…
