One use for removing random items is a word game like Scrabble in which players select seven tiles for their hand. The file WordGame.java contains a method for adding the Scrabble letter tiles to a bag. Implement a method that randomly removes seven letters from the bag and adds them to a players hand:

public static void selectLetters(Bag let, Bag player) Each time the program is run, it should pick seven random letters:

Your letters are: [A, N, T, G, I, H, R] Your letters are: [N, D, C, J, T, A, A] Your letters are: [E, I, E, D, T, S, R]
