Question

Given main(), complete the Car class (in file Car.java) with methods to set and get the purchase price of a car (setPurchasePrice(), getPurchasePrice()), and to output the car's information (printInfo()).

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, the output is:
Car's information:
Model year: 2011
Purchase price: 18000
Current value: 5770
Note: printInfo() should use three spaces for indentation.

Answer 1

Answer and Explanation:

public class Main {

int Carmodel;

int Purchaseprice;

int Currentyear;

Public void setPurchasePrice(int Purchaseprice){

this.Purchaseprice=Purchaseprice;

}

Public void getPurchasePrice(){

return Purchaseprice;

}

static void printInfo(int Carmodel int Currentyear ){

this.Carmodel=Carmodel;

this.Currentyear=Currentyear;

System.out.println(getPurchasePrice() Carmodel Currentyear);

}

}

The above java program defines a class that has three methods, a get method that returns purchase price of the object, a set method that sets purchase price of the object, and a print method that print out the information about the car object(model, year, price). The print method also takes arguments and assigns values of the arguments/parameters to the object, then prints all.
