java - How can I create a generic method signature for "any map entry" value in the parameter list and/or return type? -


in code i'm refactoring, there exists similar operation on bunch of maps. maps of following type:

map<<sometype>,double> mymap;

they undergo same transformation , converted to:

treemap<integer, <sometype>> transformedmap;

i wanted know if it's possible create generic method looks this:

public treemap<integer, <t>> transformmap(map<<t>,double> mymap){...}

what's way accomplish this? sometype kind of object/collection. replace <t> object wanted know if there better solution. above method signature, doesn't work :)

sometypes created system , operated upon in code. can't make changes source.

you close generic method solution. define generic type parameter <t>, use without own <> in return type , parameter type.

public <t> treemap<integer, t> transformmap(map<t, double> mymap) {...}
