I am writing a Spider Solitaire class in java involving the following variables and methods only(any other code needed will be written in separate classes that will be written by somebody else)

Spider Solitaire

TableauStack: array of CardStacks objects

Stock: CardStack object

Integer runCount

moveStack(int x, int y, int z)

Moves x number of cards from column y to column z.

Void dealStock()

Deals one card to each of 8 columns of cards

Sytring printBoard()

Returns all of the cards in play

Boolean gameOver()

Checks to see if foundations are full

Void newGame()

Clears the board, shuffles the deck and calls on deal()

Boolean validMove(int x, int y, int z)

Uses getValue to compare card values in order to determine if the move is valid.

Boolean validStock()

Checks if there are empty spots in the columns

Void flipCard(int index)

Flips the bottom card of index.
