Day 2 - We talked about basic primitive types, and how to print variables using System.out.println() and System.out.print(). The difference between these two is the println() goes to the next line, while print() does not. We went over Java naming conventions, arithmetic expressions, and shorthand operators.
Day 3 - We went over String concatenation, implicit & explicit casting, standard Math functions, and the mod operator. We did important practice using Math functions to create code that calculates several common problems.
Day 4 - We went over using the Scanner class to take in input to our code, practicing various ways of taking in input.. Scanners have different methods to take in different types:String (only one word/token) - sc.next();
