Question

java programming

3. Back to contract bridge. The shape of the hand (that is, how "balanced" or "unbalanced" it is) is urposes as its raw point count. Write a method often just as important for the hand evaluation p public String bridgeHandShape(String hand) that creates and returns a four-element string that tells how many spades, hearts, diamonds and clubs, in this order, there are in the hand. This result string should contain these four counts in order separated by commas, with exactly one space after each comma. Note that there should be no comma or space after the number for clubs For example, when called with the argument "Kh6c2cJd3cAd7h3d8dQdTsTh3h", the method would create and return the string "1, 4, 5, 3" since this hand contains one spade, four hearts, five diamonds and three clubs. 4. In poker, a full house consists of some three cards of equal rank, and some pair of two equal cards of another rank: for example, three tens and two fours, or three queens and two kings. Write a method public boolean hasFullHouse(String hand) that checks whether the given five-card poker hand is a full house. (Again, remember that the cards can be listed in the hand in any order. This problem is a bit difficult, which is why it is the last one today. As always, there are many possible working ways to organize the decision making logic of this method.)
