2. Implement the getSuitNum method (2 points) Complete the getSuitNum method provided in Card.java. This method takes the name of a suit as a parameter, and it should return the index of the specified suit in the SUIT_NAMES array, or -1 if the string passed as a parameter does not appear in that array. For example: getSuitNum("Hearts") should return 2, because "Hearts" has an index of 2 in the SUIT_NAMES array, and I getSuitNum( "Spades") should return 3, because Spades has an index of 3 in the SUIT_NAMES array. getSuitNum": "foo") should return -1, because foo does not appear in the SUIT_NAMES array. Notes: . Use the equalsIgnoreCase method when testing to see if the parameter matches a given element of the SUIT_NAMES array, so that the method will work for variants of the suit names in which the cases of the letters are different than the cases of the names in the array. For example, getSuitNum( "spades") and getSuitNum("SPADES") should also return 3. This method is a private helper method, and it will be used by one or more of the other methods that you write. . This method (unlike the others you will write) is static, because it does not need to access the fields in the object. Rather, we pass it all of the information that it needs as a parameter. 3. Define the fields (2 points) Each Card object should encapsulate two pieces of state: the card's rank (an integer). For numeric cards, the rank is simply the number itself (e.g., 5 cards have a rank of 5). Aces have a rank of 1, Jacks a rank of 11, Queens a rank of 12, and Kings a rank of 13. Ranks less than 1 or greater than 13 will not be allowed. the card's suit number (an integer). This is the value that would be returned by the getSuitNum method for the card's suit. The only allowable suit numbers are 0, 1, 2, and 3. For example, here is what a Card object representing an Ace of Hearts would look like in memory: +-- 1 rank 1 1 +-----+ | +-----+ | IsuitNum , 2 1 +-----+ 1 -+ Note that it has two fields, both of which are integers. For now, you only need to define the fields. Make sure to: I use the field names shown above 1 protect them from direct access by client code. In subsequent sections, you will write constructors that assign values to the fields, and that ensure that only valid values are allowed
