java - Is it useful to provide a type-safe method? -

i'm designing interface follows:

public interface parameters {      public <t> t getvalue(parametername pn, class<t> valuetype) throws classcastexception; }

an implementation obligated throw classcastexception if class instance of value returned not assignableform of class passed parameter.

does make sesnse? provides compile-time type-safety, can same explicit cast.

or it's better declare

public object getvalue(parametername pn)

leaving class-cast issues client.

i have used form of api add ability convert type 1 desired. e.g. if it's string need integer attempt parse it.

otherwise, suggest not adding method doesn't provide.

 public <t> t getvalue(parametername pn);

this avoid needing explicit cast.
