Answer:
Java Code example
Explanation:
Java Code
import java.util.Calendar;
public class CarTest {
public static void main(String [] args){
Car car1 = new Car("Honda","Civic", 2015);
System.out.println(car1.toString());
System.out.println("Car 1 is antique : "+car1.isAntique());
Car car2 = new Car("Toyota","A", 1945);
System.out.println(car2.toString());
System.out.println("Car 2 is antique : "+car2.isAntique());
Car car3 = new Car("Lamborghini","Model A", 2019);
System.out.println(car3.toString());
System.out.println("Car 3 is antique : "+car3.isAntique());
}
}
class Car{
private String model;
private String make;
private int year;
public Car( String make,String model, int year) {
this.model = model;
this.make = make;
this.year = year;
}
public String getModel() {
return model;
}
public void setModel(String model) {
this.model = model;
}
public String getMake() {
return make;
}
public void setMake(String make) {
this.make = make;
}
public int getYear() {
return year;
}
public void setYear(int year) {
this.year = year;
}
public boolean isAntique(){
return Calendar.getInstance().get(Calendar.YEAR)-year>45;
}
@Override
public String toString() {
return "Car{" +
"model='" + model + '\'' +
", make='" + make + '\'' +
", year=" + year +
'}';
}
}
Code Explanation
Declaring the instance variable and initializing those in constructor. Defining there getter setter and create a toString method, toString method will return the overall object representation.
To check whether car is antique or not, we will use java.util.Calendar class, This class will return the current date year from which we can compare the car year to check whether the car is antique or not.
Output
Output of above TestCar is given below.
__________________________________
Car{model='Civic', make='Honda', year=2015}
Car 1 is antique : false
Car{model='A', make='Toyota', year=1945}
Car 2 is antique : true
Car{model='Model A', make='Lamborghini', year=2019}
Car 3 is antique : false
