Why does this compile?
- by akf
I was taken aback earlier today when debugging some code to find that something like the following does not throw a compile-time exception:
public Test () {
HashMap map = (HashMap) getList();
}
private List getList(){
return new ArrayList();
}
As you can imagine, a ClassCastException is thrown at runtime, but can someone explain why the casting of a List to a HashMap is considered legal at compile time?
