定义一个操作中的算法骨架, 而将一些步骤延迟到子类中.
举例

/** * 创建车的抽象类 * @author fan * */public abstract class Car {    public abstract void Start();    public abstract void Go();    public void dirver() {        Start();        Go();    };}/** * 实体类 * @author fan * */public class Bc extends Car {    @Override    public void Start() {        // TODO Auto-generated method stub        System.out.println("BC Start");    }    @Override    public final void Go() {        // TODO Auto-generated method stub        System.out.println("Bc go");    }}/** * 实体类 * @author fan * */public class Bmw extends Car{    @Override    public void Start() {        // TODO Auto-generated method stub        System.out.println("Bmw Start");    }    @Override    public final void Go() {        // TODO Auto-generated method stub        System.out.println("Bmw go");    }}/** * 测试下 * @author fan * */public class Test {    public static void main(String[] args) {        Car car = new Bc();        car.dirver();        car = new Bmw();        car.dirver();    }}// resBC StartBc goBmw StartBmw go
