The general term “Debounce” originated with electronic and was used to mean “To remove the small ripple of current that forms when a mechanical switch is pushed in an electrical. circuit and makes a series of short contacts.” One can use software debouncing with a physical switch. The meaning in software development derives from this... » read more
What is Polymorphism? … To begin to understand this concept, it’s helpful to know that the word polymorphism comes from the Greek meaning many shapes (or forms).

Unlocking the Power of Unit Testing in Software Development Unit Testing is a method dedicated to validating each fragment, or “unit”, of software. This approach isn’t just about verifying if a class or a method operates correctly; it dives deep, scrutinising sets of modules, associated control data, usage procedures, and even operating procedures. But what... » read more
