I'll write a basic application that will read text from a file and write text to a file that's selected by the user. I'm using the NetBeans IDE, which makes it easy to create a simple user interface. Feel free to ask questions in the comments below!

Here's an implementation for a Stack for int values in Java.
I include the following operations:
push
pop
peek
size
empty
Note that this video is a replacement for one I made a year ago. It had some mistakes I wanted to fix, so here's the improved ver...

It's usually helpful to have the logic of an application separate from the user interface. It's a form of encapsulation that simplifies design, implementation, and testing. Here's a small, cheap example....

You can use a pattern of 1,3,5,7,... to help quickly graph a parabola when a=+/-1. If a is not +/-1 you can multiply that pattern by a. For example, for y=2x^2, the pattern becomes 2,6,10,14,.......

Writing a "for" loop using input from the user. I'll show you how to print out the numbers from 1 to n, where n is the input value. I also show how to handle "bad" input from the user, like non-numbers or invalid numbers....

Finding intersections points between two lines using the Substitution method. Each example in this video has parallel lines, so there is either no intersection point (lines are distinct) or infinitely-many intersection points (lines are equivalent)....

A short introduction to using UML to design a simple application. In this case it's a game. I talk about how UML works (i.e. what the boxes and arrows are for), and also about how it's good practice to separate application logic from user interface.

I copied some pages for class today. First I made 25 copies of a single page. Then, I made 25 copies of two pages (50 total) and collated them (so pages A and B came out in sequence, then A and B again, and so on). How much longer does it take to use coll...

I show how to simulate 10 turns in each of two dice games for my MDM4U class. I'm using Google Sheets because it's fast and reliable. The same approaches work for Excel and Numbers, sometimes with slight differences in formula names.
My apologies for the...
