Part 4: Implementing PokemonGame.java (3 points) (creating and testing) (Pair programming allowed)

You will complete the method public void startJourney() in PokemonGame.java. This section will walk you through the code you need to add, marked with TODO in the starter code.

4.1 Implement and call the two helper methods:

public static Berry getUserBerry(Scanner myScanner)

This method should do the following:

1. Prompt the user to type in what berry they would like to use by using the prompt string in the PROMPT_MSG_BERRY variable.
2. if the Berry they have entered is not one of the Berries we recognize, print an error message. See PROMPT_MSG_BERRY_WRONG_INPUT and go to step 1. .
3. If the user types skip, return a new Berry object with an empty string for the berryName and 0 for both the patienceInc and speedDec.
4. Call useBerry to determine whether the Berry exists in the backpack.
5. If they do not have that berry in their backpack print You don't have any [Berry type] left!" and go to step 1.
6. If they do, return the Berry object from your useBerry method call.

You can test this method interactively once you have the complete startYourJourney method working. There are no required tests to write here.

public static Pokeball getUserPokeball(Scanner myScanner)

This method should do the following:

1. Prompt the user to type in what pokeball they would like to use by using the prompt string in the PROMPT_MSG_POKEBALL variable.
2. If the Pokeball they have entered is not one of the Pokeballs we recognize, print out PROMPT_MSG_POKEBALL_WRONG_INPUT go to step 1.
3. Call useBall to determine whether the Pokeball exists in the backpack.
4. If they do not have that pokeball in their backpack print You don't have any [PokeBall type] left!" and go to step 1.
5. If they do, return the PokeBall object from your useBall method call.

You can test this method interactively once you have the complete startYourJourney method working. There are no required tests to write here
