Consider a class called ChessPiece. This class has two instance data, String type and int player. The variable type will store "King", "Queen", "Bishop", etc. and the int player will store 0 or 1 depending on whose piece it is. We wish to implement Comparable for the ChessPiece class. Assume that, the current ChessPiece is compared to a ChessPiece passed as a parameter.
Pieces are ordered as follows:
"Pawn" is a lesser piece to a "Knight"
a "Bishop" and "Knight" are equivalent for this example
both "Bishop" and "Knight" are lesser pieces to a "Rook"
a "Rook" is a lesser piece to a "Queen"
a "Queen" is a lesser piece to a "King".
