Create a class named TennisGame that holds data about a single tennis game. The
class has six fields: the names of the two players, the integer final scores for the
players, and the String values of the final scores. Include a get method for each of
the six fields. Also include a set method that accepts two players’ names, and
another set method that accepts the two integer final score values. The integer final
score for a player is the number of points the player won during the game; this value
should be in the range of 0 through 4. If either of the set method parameters for a
score is not in the range of 0 through 4, assign 0 to both scores and assign “error” to
the String scores. If both players’ score parameters are 4, assign 0 to both scores
and “error” to the String scores. The String score values are set by the method that
sets the integer score values. The String final score for each player contains the
traditional names for points in tennis: love, 15, 30, 40, or game, respectively, for the
values 0 through 4. Create a subclass named DoublesTennisGame that includes two
additional fields for the names of the first two players’ partners. Include get methods
for the names. Override the parent class setNames() method to accept the names of
all four players. Write an application named DemoTennisGames that instantiates
several objects of each of these classes
