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.
The object: An object is usually defined as an instance of a class. In simple terms, it is an analogue to a pastry out of a mold. As long as the same mold is used, one can create a pastry of the same shape (this shows a class can be instantiated multiple times and each of them is like a copy out of that template).
