just for java

Airline class The constructor in the Airline class sets name, initializes the totalPlanes to 0, and initializes the array to hold. 10 planes. The Airline toString method returns the name of the Airline, total number of planes, and the total number of passengers that have flown on all their planes. The addPlane method adds a plane object to the array of Planes that the Airline has percentageFull returns numberOfAllPassengersumberOfAllSeats in the Planes in the airline to see how full all the planes are Plane class The constructor sets the name of the plane (flight name), the total number of seats on the plane and sets numPassengers to 0 addPassenger method increases the numPassengers by the number num (do appropriate checks in this method) hasMoreSeats (Plane p) compares two Plane objects (this Plane and Plane p) to see which one has more seats on the plane(ie., see which one is bigger). Properly test your classes by performing the following operations in a demo class, at minimum. Create an Airline class with at least 3 Plane objects. Add passengers to all the Planes. Add the planes to your airline. Print out the totalNumber of planes that the airline has. Print out the total number of passengers on all the Planes. (use the method getTotalPassengers in the Airline class). Add some more passengers to your second plane. Print out the percentageFull (totalPassengers from all planes/totalSeats from all planes) on all the Planes. Print out the plane object that has the most seats. Call the toString method in the Airline Class
