Question about Object

If a method takes an Object parameter, can this parameter be type casted by
any class?

Example:
public int compareTo(Object o) {
Name n = (Name) o;
}

public int MultiplyPrint(Object o) {
String testString = (String) o;
Int num = Integer.parseInt(testString);
int theResult = Math.pow(num,2);
return theResult;
}

public Orange Apple2Orange(Object o) {
Apple apple = (Apple) o;
// Convert to Orange
Orange orange = (Orange) apple;
return Orange;
}

Also, is it poor programming style to rely on type casting?

TIA

You can TRY to cast an Object to another type, but of course, if the Object
isn't an instance of that type, you'll get a ClassCastException. For
instance, if the Object is actually a String, and you try to cast it as an
OutputStream, it won't work.

Whether or not it's poor programming to cast a type all depends on the
situation. I don't think there's a single simple answer to that question.
