急求达人帮忙用java编一个汽车和垃圾车类

publisabstractclassCar{

privateststicfinalintcar_number;

publicgetCar_number();

publicsetCar_number();

}

publicclassTrashCarestendsCar{

privateStringcapacity;

publicgetCapacity();

publicsetCapacity();

publicstaticvoidmain(String[]args){

TrashCartrashCar=newTrashCar();

}

}

注：car一般是抽象类不能实力化。只能被继承car是把所有车比如卡车、轿车、吉普车、面包车等抽象成的类。
