if（true）会做什么？

在这种情况下if（true）会做什么？我正在学习构建象棋引擎程序的教程。下面的代码行让我感到困惑，我不确定它到底能做什么。

public class Knight extends Piece { private final static int[] CANDIDATE_MOVE_COORDINATES = {-17, -15, -10 , -6, 6, 10, 15, 17};

Knight(final int piecePosition, final Alliance pieceAlliance)
{
    super(piecePosition, pieceAlliance);
}

@Override
public List<Move> calculateLegalMoves(Board board)
{
    int candidateDestinationCoordinate;
    final List<Move> legalMoves = new ArrayList<>();

    for (final int currentCandidate : CANDIDATE_MOVE_COORDINATES)
    {
        candidateDestinationCoordinate = this.piecePosition + currentCandidate;
        if (true)
        {
            final Tile candidateDestinationTile = board.getTile(candidateDestinationCoordinate);
            if (!candidateDestinationTile.isTileOccupied())
            {
                legalMoves.add(new Move());
            }
            else
            {
                final Piece pieceAtDestination = candidateDestinationTile.getPiece();
                final Alliance pieceAlliance = pieceAtDestination.getPieceAlliance();
                if (this.pieceAlliance != pieceAlliance)
                {
                    legalMoves.add(new Move());
                }
            }
        }
    }
    return ImmutableList.copyOf(legalMoves);
}

}
