I just wanted to know what would happen if you abuse the CharStack class by pop()ing more characters than you push()? Would it be an error of out of exception or something else.

Read the API docs for the class.

Besides... Your code should be checking not to pop() if there are 0 elements in your stack.

Which CharStack class would that be?

Agreed... I don't find any documentation about a class called CharStack.
A stack (of any type) is a list construct the programmer must create via array.

So this is a class that you have written / must write? In that case the answer to your original Q is "that's up to you". Throwing an Exception would be a reasonable thing to do, because it would be an error.
