Java中抽象类和接口之间的区别
以下是Java接口和抽象类之间的显着区别。
示例
public class Tester {
public static void main(String[] args) {
Car car = new Car();
car.setFuel();
car.run();
Truck truck = new Truck();
truck.setFuel();
truck.run();
}
}
interface Vehicle {
public void setFuel();
public void run();
}
class Car implements Vehicle {
public void setFuel() {
System.out.println("Car: Tank is full.");
}
public void run() {
System.out.println("Car: Running.");
}
}
abstract class MotorVehicle {
public void setFuel() {
System.out.println("MotorVehicle: Tank is full.");
}
abstract public void run();
}
class Truck extends MotorVehicle {
public void run() {
System.out.println("Truck: Running.");
}
}输出结果
Car: Tank is full. Car: Running. MotorVehicle: Tank is full. Truck: Running.
