Generally, if you write a class and do not include any constructor, Java provides automatically for you a default constructor (one without parameters), which initializes all instance variables of the class (if there are any) with some default values (0, null, or false). I was wondering if there was a way I could keep using the stack instead of the stack restarting once the program evaluates an expression. However, you may use the call to super() with arguments if the parent's constructor takes parameters, and you wish to specify them.
