Since this roundup of rainbow beaches began with white (technically, the blending of all colors), it seems appropriate to end with black, which is the absence of color. While that may be true in scientific terms, there is no absence of color at the worldâs black sand beaches â they are simply a stunning result of volcanic activity near a coastline.
definition - instance (computer science) Instance (computer science) In object-oriented programming an instance is an occurrence or a copy of an object, whether currently executing or not. Instances of a class share the same set of attributes, yet will typically differ in what those attributes contain.
An object that is created using a class is said to be an instance of that class. We will sometimes say that the object belongs to the class. The variables that the object contains are called instance variables. The methods (that is, subroutines) that the object contains are called instance methods.
