SHOW ALL YOUR WORK. REMEMBER THAT PROGRAM SEGMENTS ARE TO BE WRITTEN IN JAVA.
• Assume that the classes listed in the Java Quick Reference have been imported where appropriate.
• Unless otherwise noted in the question, assume that parameters in method calls are not null and that methods are called only when their preconditions are satisfied.
• In writing solutions for each question, you may use any of the accessible methods that are listed in classes defined in that question. Writing significant amounts of code that can be replaced by a call to one of these methods will not receive full credit.
The Bus class simulates the activity of a bus. A bus moves back and forth along a single route, making stops along the way. The stops on the route are numbered consecutively starting from 1 up to and including a number that is provided when the Bus object is created. You may assume that the number of stops will always be greater than 1.
The bus starts at the first stop and is initially heading toward the last stop. At each step of the simulation, the bus is at a particular stop and is heading toward either the first or last stop. When the bus reaches the first or last stop, it reverses direction. The following table contains a sample code execution sequence and the corresponding results.

The route for bust has three stops numbered 1-3
bus1 is at stop I (first stop on the route.
bus1 moves to the next stop (2).
bus1 is at stop 2
bus1 moves to the next stop (3).
hast is at stop 3
bus1 moves to the next stop (2).
bus1 is at stoo 2
bus! moves to the next stoo n
bus1 moves to the next stop (2).
bus1 is at stop 2.
bust is still at stop 2
The route for bus2 has five stops numbered 1-5.
bus1 is still at stoo 2
bus2 is at stop 1 (first stop on the route).
Write the complete Bus class, including the constructor and any required instance variables and methods. Your implementation must meet all specifications and conform to the example.
