Data Types

In data types, there are both Primitive Types in Java and Wrapper Classes.
To identify if a data type is primitive or not, you must check its capitalization.
- Primitive types will not be capitalized (for example: int, boolean, char, byte, long) whereas Wrapper Classes will be capitalized (for example: Int, Double, Boolean, String)

Descriptions of the mathematical operations combine to form result of the operation.
Primitive types usually aren’t alone and will have primitive type doubles and/or wrapper class double.

can create a new object without using variables
import the java scanner along with whatever else you need to create certain functions
2D array seen in java objects notebook with the color names in one column (1D), and the color codes in the other column (another 1D)
static means its not part of the object
- just in the class definition
static public void main(String[] args)
- used to drive a class
new Menu();
- contains while loop within it to restart the menu until we quit the program with the 0 input
The extends feature in java is used to extend a class in order for the subclass (child) to inherit from the superclass (parent)
To create a new object: specify the class name, followed by the object name, and use the keyword new
use main.java
Use constructors to initialize objects and set some object attributes
- constructors can have as many parameters as needed

can inherit properties from another
color is once again being randomized
seeing usage of frame.set, frame.add to show use of java objects
- dot notation is the referencing of object
