Example with a context (Object-Oriented Design in Java by Bill Mccarty and Stephen Gilbert (1998)):
Stephen Gilbert teaches computer science at Orange Coast College in Costa Mesa, CA. Steve saw his first computer play tic-tac-toe in the summer of 1960 and wanted one of his own ever since. When he purchased his first machine, a VIC-20 (which he subsequently trained to play an unbeatable game), his life took a sudden turn after years spent as a carpenter, chicken picker, and offset press operator.
What does computer play mean exactly?
