Question

Can this be done in Java

public <T> T[] getAttr(String s) {
    Object x = getSomething(s);
    com.class."s"[] y = (com.class."s"[]) x;
    return y;
}

I realise this is all very rough. But the basic principle can this be achieved in Java.

EDIT:

Guys I already have the object I wish return x. I just want it returned as the correct type. I.e the class version of s

Answer 1

get the class

Class<?> theClazz = Class.forName("com.class."+s);

create an array of the specified runtime type and length:

java.lang.reflect.Array.newInstance(theClazz, length);

You are going to have to suppress some warnings about type-safety. There is no way around that if you really want to go from Strings. Maybe pass in a Class object instead, then it can be made type-safe.
