can not be, because you're not thinking right, the objects not be class.
If you want to know that object is, you need to access the objects and get
the properties, then you know that object is.
Example:
public void method(Person p) {
if (p.getName().equal("anthony")){
// p is anthony
} else if (p.getName().equal("richard")) {
// p is richard
}
......
}
this is the only way.
Hope it's help and sorry for my English!!!!
