Complete the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information. Ex: If the input is: 2011 18000 2018 where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs: Car's information: Model year: 2011 Purchase price: $18000 Current value: $5770 Note: print_info() should use two spaces for indentation.

JAVA QUESTION REQUIRES SEPARATE CLASSES, CANNOT BE WRITTEN IN ONE MAIN METHOD E.G. ACCOUNT SECTION WRITTEN IN ACCOUNT CLASS, CUSTOMER SECTION WRITTEN IN CUSTOMER CLASS ETC. Phase 2 In this phase you’ll be writing code within the methods of your classes to make the tests pass. Account Each account should have a constant, unique id. Id numbers should start from 1000 and increment by 5. The ACCOUNT_ID attribute should be initialised when the account object is created. The id should be generated internally within the class, it should not be passed in as an argument. The deposit method should increase the balance by the value passed in as an argument. The withdraw method should reduce the balance by the value passed in as an argument. It should return the value of the argument The account should be able to go overdrawn The correctBalance method should change the balance to match the value passed in as an argument.
