Question 13

Code Description Ch 07-1
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".

-Refer to Code Description Ch 07-1: To implement Comparable for the ChessPiece class, the current ChessPiece's type is compared to a ChessPiece passed as a parameter. The method should return 0 if the types are equal, -1 if this piece's type is a lesser piece than the parameter's type, and 1 if this piece's type is a greater piece than the parameter's type. Create this code.

Accepted Answer

public int compareTo(ChessPiece a)
{
if

Question 14

B)  find syntax errors 
C)  find logical and run-time errors 
D)  evaluate how well the software meets the original requirements 
E)  give out-of-work programmers something to do 
A)  ensure that the software has no errors

Question 15

Accepted Answer

A) True 
 B)False

Question 16

Assume a class Foo implements Comparable. Without knowing anything else about the Foo class, write an equals method that returns true if the Foo parameter passed to this Foo is equal to this Foo as determined by using the implementation of Comparable.
