I have a HashMap which contains 2 classes, class A or class B.
I iterate through the HashMap and it returns Objects of either A or B
I want to call a certain function of A or B called "doSomething()", but I also have to get a
String from that class that is specific to that Object.
So I didn't know to what class to cast the object.
in my first attempt I created a third class that extends JPanel, with a variable that would be set to the type of class the object was:
so that I could cast the object to C and get the type of class variable and cast it based on what typeofclass it was.
Then i remembered interfaces.
I'd just implement an interface with doSomething() and cast my Object from the HashMap to that interface.
But interfaces only have final variables...right? what If I had variables I needed to access of the implementing classes?
ugh im stuck. help please.
