An odometer records a car’s mileage. It contains a number of counters that increment as the car travels. Each counter shows a digit from 0 to 9. The rightmost counter increments the fastest, increasing by 1 for every mile traveled. Once a counter reaches 9, it changes to 0 on the next mile and increases by 1 the value on the counter to its left. You can generalize the behavior of such digit counters by giving them symbols other than the digits from 0 to 9. Examples of such digit counters include the following:

• A binary odometer whose counters each show either 0 or 1

• A desktop date display with three counters, one each for the year, month, and day

• A dice roll display whose counters each show the spots for a single die

Write a Java interface for any class that represents a digit counter. Also, write a Java interface for a general counter that has up to four digit counters. Include comments in javadoc style.
