接口
接口是一个空的外壳。
// I say all motor vehicles should look like this:interface MotorVehicle{
void run();
int getFuel();}// My team mate complies and writes vehicle looking that wayclass Car implements MotorVehicle{
int fuel;
void run()
{
print("Wrroooooooom");
}
int getFuel()
{
return this.fuel;
}}抽象类
// I say all motor vehicles should look like this:abstract class MotorVehicle{
int fuel;
// They ALL have fuel, so lets implement this for everybody.
int getFuel()
{
return this.fuel;
}
// That can be very different, force them to provide their
// own implementation.
abstract void run();}// My teammate complies and writes vehicle looking that wayclass Car extends MotorVehicle{
void run()
{
print("Wrroooooooom");
}}实施
