Initialization: The process of assigning an initial value to a variable when it is declared. For boolean instance variables, if no explicit initialization is provided, they will default to false.
Data Types: In programming, data types define the kind of value that a variable can hold. Boolean is one of the fundamental data types in most programming languages.
Variable Declaration: The act of creating a new variable and specifying its type. When declaring boolean instance variables without explicitly initializing them, they will have their default values automatically assigned.
