Make your own Stack class that is based on the following UML diagram. Be sure to test it before you do the bracket matching part Stack), write a java program that indicates if an expression contains matching opening and closing brackets. For example the input String "(Hello(Bill 3)" has matching brackets, but the String "a(b)" does not, nor does the String" Algorithm: Make a Stack of Character For each char in the String... if charpush it if char '), pop When all char's have been processed if the Stack is empty the brackets match. Make sure you don't try to pop from an empty stack.- You don't have to read any input, just create a String with your bracket expression
