android - Makes it sense to create an object of a class which extends Service? -

does make sense create object of class extends service? mean following:

mainactivity.java:

public class mainactivity extends activity{    @override    public void oncreate(...){        myservice service = new myservice(...);        ...    }    ... } 

service.java:

public class myservice extends service{    public myservice(...){       ...    }    ... } 

i think not make sense, because e.g. in opinion not possible unregister service. reason: service never started startservice(...).

does has hints me? thank you!

although can create object of class extends service doesn't make programmatic sense. fundamental reason create object use functionalities class offer. in android paradigm, rather bind service use functionalities.
