I want to create a method that uses dot(.) operator while calling in JAVA -

i wanted create method uses . while calling.

string a="alpha",b="beta"; a.compareto(b); 

so how access a define method compareto(). can access string b in definition of compareto(), compare b need a well. how can access a. in definition of method.

string already has compareto.

if you're talking adding new methods existing classes without access class's source, c#'s extension methods, doesn't exist in java.
