Parameter class casting problem

Question

The question is: how to get the right method based on the type of the parameter passed?
Here is the code:
public class Test {
  public static void main(String[] args) {
    Integer l = 57; // automatic boxing
    Object o = 43;  // automatic boxing and widening casting (?)
    print( l ); // OK: calls Integer
    print( o ); // calls Object: not what I want, but could be
    print( (Integer)o );  // OK: calls Integer
    print( Integer.class.cast(o) ); // OK: calls Integer
    print( o.getClass().cast(o) );  //  NOT OK: dinamic casting does't work?
  static void print( Integer l ) {
    System.out.println("Integer: " + l.toString());
  static void print( Object o ) {
    System.out.println("Object: " + o.toString() + " (" + o.getClass().toString() + ")");
}

Answer 1

Method overloads are resolved at compile time; meaning only the compile time type of the expression used as parameter is taken into account.
Class<T>.cast(Object)returns T.
Class<Integer>.cast returns Integer, so the first overload is chosen.
Class<Object>.cast returns Object, so here the second overload is chosen.
