stance method.
Listing 2-9. Declaring a printDetails() instance method in the Car class
class Car
{
String make;
String model;
int numDoors;
Car(String make, String model)
{
this(make, model, 4);
}
Car(String make, String model, int numDoors)
{
this.make = make;
this.model = model;
this.numDoors = numDoors;
}
void printDetails()
{
System.out.println("Make = "+make);
System.out.println("Model = "+model);
System.out.println("Number of doors = "+numDoors);
System.out.println();
}
public static void main(String[] args)
{
Car myCar = new Car("Toyota", "Camry");
myCar.printDetails();
