The first part has been designed to cover the first week of the course. You should reserve well above 10 hours for each part of the course, depending on previous experience with …

During this course, you will learn the basics of computer programming, along with algorithms and object-oriented programming through the Java programming language.

The program should break as it doesn't know how to convert these inputs into numbers. We'll learn how to deal with exceptional cases like these in the advanced programming course.

When the button is pressed, the program prints the text "Pressed!" to the console. Event handlers attached to user interface components, such as the EventHandler used previously, are always …

Object-oriented programming is primarily about isolating concepts into their own entities or, in other words, creating abstractions. Despite the previous example, one might deem it pointless …

Test the program flow with different inputs and find out the sort of input that causes the program to not work as desired. If you received an error in the tests, the tests may also indicate the input …
