Chess rules library written with Java 8.
Starting board can be created using BoardUtil.createStartingBoard().
Moves can be generated for each piece using getPieces-method in MoveUtil by passing a Board-object to it and then asking each piece for their individual moves.
Example that will fetch all possible starting moves (wrapped inside Board objects) for white player:
final Board board = BoardUtil.createStartingBoard();
List<Board> boardStatesOfMoves = MoveUtil.getPieces(board, true)
.stream()
.map(piece -> piece.getMoves(board))
.flatMap(move -> move.stream())
.collect(Collectors.toList());
