• 本质与使用场景

public interface AirShipBuilder {

    Engine builderEngine();

    EscapeTower  builderEscapeTower();

}

public class SxtAirShipBuilder implements AirShipBuilder{  //StringBuilder,以后学习XML解析中，JDOM库中的类：DomBuilder,SaxBuilder

    @Override
    public Engine builderEngine() {
        System.out.println("构建尚学堂牌发动机");
        return new Engine("尚学堂牌发动机");
