JAVA problem :

Write a class ParkingGarage which simulates a garage for parking Vehicles. The garage should have have enough capacity to park 20 Vehicles or 25,000 pounds. It should refuse to park any Vehicle that would push the garage over either of these limits. Note that ParkingGarage should be a well-behaved class; in particular, it should be possible to create multiple independent ParkingGarages in one program. ParkingGarage should have a main routine which demonstrates its capabilities. main( ) need not accept any user input.
