The static modifier is used to create variables and methods that will exist independently of any instances created for the class. All static members exist before you ever make a new instance of a class, and there will be only one copy of a static member regardless of the number of instances of that class.

all instances of a given class share the same value for any given static variable.

Static can not refer to this or super.

static methods can't be overridden!

Static variables are also known as class variables
