3. (5 points) You're writing a Nethack-style text-based role-playing game that supports saving the game's current state to a text file. You decide to represent items in your character's inventory using certain symbols in the file: +- weapon - potion * - dark chocolate bar (your character is magically prevented from carrying inferior milk chocolate bars) Within a source file named NethackClone.java, write the static method int[] countItems (String s) This returns an array containing the quantity of weapons, potions, and dark chocolate bars (in that order) represented within the string s. Assume that s contains only the three characters above. For example, calling countItems ("@@+**+ ***") should return the array {2, 3, 5}
