Method Overriding
occurs when a subclass has the same method as the parent class
Decomposition
breaking down large problems into smaller ones each with a method that defines a larger problem
Algorithm
sequence of finite steps designed to solve a specific problem
Information hiding
encapsulating data within a class and restricting access to specific components using access modifier
Static variable
the variable belongs to the class only ; not any instance of it
Static method
a method that belongs to a class rather than any instance of it
Final
