    What did you try? Where are you stuck? What basics of java programming do you know? All these questions boil down to me suggesting you try something to accomplish your tasks, make an attempt and research a bit, ask a specific question about code you have - rather than implying you wish someone else to do it for you.

    You can use a boolean and an if statement. If the boolean is true print '+' else print '-'. Print value. Change value of boolean.
