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.
Each object is said to be an instance of a particular class (for example, an object with its name field set to Mary might be an instance of class Employee). Procedures in object-oriented programming are known as methods; variables are also known as fields, members, attributes, or properties.
