以购买电话卡为例说明 简单工厂模式
public interface Card {
public void buyTelCard();
}public class MobileCard implements Card {
@Override
public void buyTelCard() {
System.out.println("购买移动卡");
}
}public class UnicomCard implements Card {
@Override
public void buyTelCard() {
System.out.println("购买联通卡");
}
}public class CardFactory {
public Card buyCard(String styleName) {
if (styleName.toLowerCase().equals("mobile")) {
return new MobileCard();
} else if (styleName.toLowerCase().equals("unicom")) {
return new UnicomCard();
}
return null;
}

public class Test {
public static void main(String[] args) {
