Size 19 is common. The first and second players place pieces on the board that are black and white, respectively. Each piece is placed in an unoccupied grid position.

Class Connect6State

Cloneable
Connect6State - A representation of a Connect6 game state. We assume a square grid board size specified to be a positive integer less than or equal to 26. Size 19 is common. The first and second players place pieces on the board that are black and white, respectively. Each piece is placed in an unoccupied grid position. On the first turn, the first player places one piece. Afterwards, players alternate placing two pieces per turn. Play continues until either one player completes a consecutive line of 6 or more of their pieces or no play is possible. The player with 6 or more pieces in a horizontal, vertical, or diagonal line is the winner. If no legal play is possible, the game is a draw

Field Detail
- BLACK
  public static final int BLACK
  a constant indicating a black player/piece
  See Also:Constant Field Values
- WHITE
  public static final int WHITE
  a constant indicating a white player/piece
  See Also:Constant Field Values
- NONE
  public static final int NONE
  a constant indicating no player/piece
  See Also:Constant Field Values

Constructor Detail
- Connect6State
  public Connect6State(int size)
  Creates Connect6State instance with an empty size-by-size grid and black to play.
  Parameters:size - game grid size

Method Detail
- getPiece
  public int getPiece(int row, int column)
  Given the row and column, returns the piece (BLACK, WHITE, or NONE) at that grid position.
  Parameters:row - - grid position rowcolumn - - grid position columnReturns:the piece (BLACK, WHITE, or NONE) at position (row, column)
- getPlayer
  public int getPlayer()
  Returns the current player (BLACK or WHITE).
  Returns:the current player (BLACK or WHITE)
- getSize
  public int getSize()
  Returns the grid size.
  Returns:the grid size
- getWinner
  public int getWinner()
  Returns BLACK, WHITE, or NONE, if black has won, white has won, or no player has won, respectively. A player wins by placing 6 pieces consecutively in a line horizontally, vertically, or diagonally.
  Returns:the winner BLACK, WHITE, or NONE (if there is no winner)
- playPiece
  public boolean playPiece(int row, int column)
  The current player tries to play a piece at the given position. If the move is illegal (e.g. out of bounds, already occupied), false is returned. Otherwise, the current player's piece is placed at the given row and column, the current player changes or doesn't change according to the game rules, and true is returned. The current player changes after the first play, and after every two plays of a player thereafter.
  Parameters:row - attempted play rowcolumn - attempted play columnReturns:whether or not the attempted play was legal
- toString
  public java.lang.String toString()
  Returns a String representation of the board. A '.' denotes an empty grid position. A '*' denotes a black piece. A 'o' denotes a white piece. Each grid row begins with a 1-based row number from 1 to size, right-justified within a width of 2 characters and followed by space-separated pieces of that row. Rows are printed in decreasing order, so that printed row 1 (internal grid row 0) is printed last. Under the board and aligned with each column, print successive lowercase letters 'a', 'b', 'c', ... until each column (of 26 columns max) is labeled with a letter. Thus, internal grid column number c is labeled by character (char) ('a' + c).
  Overrides:toString in class java.lang.Object
- isGameOver
  public boolean isGameOver()
  Return whether or not the game is over.
  Returns:whether or not the game is over
- clone
  public java.lang.Object clone()
  Returns a deep copy of this Connect6State object. This should be a deep clone. Changes to the copy should not alter the original, and vice versa.
  Overrides:clone in class java.lang.ObjectReturns:a deep copy of this Connect6State object
