Constructor Details

EmptySea

public EmptySea()

Sets the inherited length variable and initializes the hit array, based on the size of this Empty Sea (1 tiles).

Method Details

shootAt

public boolean shootAt(int row,
 int column)

Since an EmptySea is empty by definition, shooting at one will always be a miss.

Overrides:

shootAt in class Ship

Parameters:

row - the row of the shot

column - the column of the shot

Returns:

false always, since nothing will be hit.

isSunk

public boolean isSunk()

Since an EmptySea is empty by definition, it is not possible that one can be sunk.

Overrides:

isSunk in class Ship

Returns:

false always, since nothing will be hit.

toString

public String toString()

Returns a single character String to use in the Ocean's print method. This method can only be used to print out locations in the ocean that have been shot at; it should not be used to print locations that have not been the target of a shot yet. Since an EmptySea is empty by definition, targeting it will always result in a miss so return "-".

Overrides:

toString in class Ship

Returns:

"-" always, since nothing will be hit

getShipType

public String getShipType()

Specified by:

getShipType in class Ship

Returns:

"empty", indicating that this is an Empty sea tile.
