Write a program to define the 'Course' class that has a name, numberOfSeats, department and numberOfCourses (which will keep track of how many objects have been created of this class and allow users to get that value). The variable numberOfCourses will be shared by all instances of the class, so declare this variable as static. Have a method to set objects and another method to getNumberOfCourses. Since this method will return a value that is shared by all classes (which means it is not tied to a specific object), implement this method as static. Write a test program to do the following: Create object C1(CS155,40,CS) Invoke getNumberOfCourses() Create object C2(CS265,40,CS) Invoke getNumberOfCourses() Create object C3(CS300,25,CS) Create object C4(CS315,30,CS) Invoke getNumberOfCourses ()
