 Like all programming languages, Java allows you to combine groups of commands into a single unit that forms an abstraction.  For example, the words shown above that draw a square could be combined into a single new word that can be used to replace the individual words.  This allows programs to be built with increasing abstraction so high level concepts such as 'put the ring on the peg' can be expressed clearly and concisely.
