Strategy overloading, Conversely, refers to differentiating the code made use of to deal with a information determined by the parameters of the tactic. If a single views the obtaining item as the initial parameter in almost any system then overriding is simply a Specific circumstance of overloading the place the choice relies only on the first argument.[two] The next straightforward Java instance illustrates the real difference:[three]
