Java Forum / General / October 2005Generic method question
Hi, I am using a method: Object lookup(Class c) {...} The lookup method return an instance of the class c. Is there is any way using java generic methods to insure compile-time type checking? Something like: T lookup(Class <T?????>) Thanks. > Hi, > [quoted text clipped - 8 lines] > > Thanks. I assume you mean something like: public <T> T lookup(Class<? extends T> clazz) throws IllegalAccessException, InstantiationException { return clazz.newInstance(); } P.s. compile time type safety is pretty much _all_ generics are good for ;)  SignatureRoss Bamford - rosco@roscopeco.remove.co.uk OK, that's working. Thanks all. Hi, > Hi, > [quoted text clipped - 6 lines] > type checking? Something like: > T lookup(Class <T?????>) Yes, exactly: T lookup(Class<T> c) {...} Ciao, Ingo >Is there is any way using java generic methods to insure compile-time >type checking?
