Parameter class casting problem
The question is: how to get the right method based on the type of the parameter passed?
Here is the code:
publicclass Test{
publicstaticvoid 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?
}
staticvoid print( Integer l ){
System.out.println("Integer: " + l.toString());
}
staticvoid print( Object o ){
System.out.println("Object: " + o.toString() +" (" + o.getClass().toString() +")");
}
}
