Rewatch:

• Casting
• Boxing and Unboxing
• Byte addition exception
• Protected access specifier
• Object type vs reference type (reference type is used when accessing instance data, static data and static methods, object type is used in every other case)
• Finally block special case with return statements
• Special handling of exceptions thrown by AutoCloseable interface's close function using the getSuppressed() function
• Just this slide is very important

Rules:

variable[] = [] # append new item in the array
variable[integer] = [] # alter the (already-available/pre-existing) index in the array
variable[non-integer] = {} # object
y[][non-integer] = [{}] # create an object as a newly created array element
variable[integer][non-integer] = [{}] # alter the object at the pre-existing indexed position
y[non-integer][] = {[]} # append a new array element to the key
variable[non-integer][integer] = {[]} # alter the pre-existing array index of the key-value object
