In Java Create a class named TreasureBox that contains:
(Be sure to set the appropriate access modifiers – private/public)
a. A public static double field name PTS_PER_GOLD_COIN. Set this constant to 15.0
b. A public static double field name PTS_PER_SILVER_COIN. Set this constant to 7.5
c. An int data field for the number of gold coins in the box (can be negative or
positive).
d. An int data field for the number of silver coins in the box (can be negative or
positive).
e. A double data field for total value of points of the coins contained in the treasure box
f. A private method named updateTotalPoints that has no parameters and no return
values. This method updates the attribute for the total value of points in the
treasure box based on the number of gold and silver coins and the points per each
coin. Be sure to use the constants and do not ‘hard code’ the values 15 and 7.5 in
this method. This method is an example of a helper function to be used by ALL
methods that need to update the total values of points in the treasure box.
g. A constructor that accepts two values and initializes both attributes in the following
order: number gold coins and number of silver coins. The constructor should
update the attribute for total number of points based on the number of gold and
silver coins in this treasure box. (Use your helper function!)
h. A constructor that accepts no values and initializes both the number gold coins and
number of silver coins to 0. This constructor should call the constructor you created
in the previous step with the appropriate values.
