Throughout much of our study and development of human cognition and its replication in the various forms of artificial intelligence, there has been an underlying assumption from which we have based our work...
I was recently assigned to read this entire article/essay/magazine in a class of mine and was blown away by how comprehensive it is. If you guys are just beginning to dip your toes into IT or software development, then this is a must-read! To read: https://www.bloomberg.com/graphics/2015-paul-ford-what-is-code/
Hey guys! So, this time, we're going look at other methods we can use to construct proofs when just deriving from the premises isn't enough. Conditional Proof (CP) The setup: Basically, you use this method when the conclusion or a part of the conclusion you want is a conditional. This makes it so you assume... Continue Reading →
So, recursion, one of the hardest units in APCS. The concept is pretty easy but the execution is a bit trickier. Today, I'm going to pass on a trick that my teacher taught me on how to trace your way through a recursion problem. I'm going to assume that y'all already know what recursion is... Continue Reading →
Alright, it's time to tackle 2D arrays and arrayLists. 2D arrays are basically arrays of arrays. First off, 2D arrays: 2D Arrays To start off with, the declaration and instantiation. Since 2D arrays are objects, we will use the new operator. There are several ways to do this: The "normal" way:data type   name = new data type... Continue Reading →
Sorting methods as it pertains to arrays isn't the simplest thing to wrap your head around but the concept and the way they should work should be pretty intuitive. You would need to know about two main sorting methods in APCS; the selection sort and the insertion sort. Like the different types of loops, both of these... Continue Reading →
Arrays are basically lists of things. This list can contain both objects and primitive data. The basic array can be declared and instantiated as such: (data type)[ ] (arrayname) = new (data type) [(number of elements)]; Since arrays are considered as objects, the declaration and instantiation follow the pattern of other objects. So, if I... Continue Reading →
This lab review goes over three labs within Chapter 2: the base conversion lab, the circle lab and the string manipulation lab. Even if you aren't an AP Comp Sci student, if you are learning Java and want some practice, these lab reviews are a good resource. Chapter 2 covers the concept of objects and primitive data.
TL;DR -- Basically, I made a game on code.org for my AP Computer Science Principles (APCSP) class and it's a maze game and I've included the code for it, which can give you a couple of ideas for your own creations and serve as an example, and I've also included a video that shows you...
