if you have a class with a set of methods and your are using netbean to code 
when accessing the methods i just type the intiated class with a dot and all viewable methods are displayed for you to choose of your choice

I would like to do the same to in maps . Instead of using getObject(key) to just type the map 
with a dot and all keys are displayed for me to choose any key of my choice . In this case I don't have to know the keys in the map. please help
