地址类

java 复制代码

public class Address {
    public void street() {
        System.out.println("普通的街道");
    }

    public void zip() {
        System.out.println("普通的邮政编码");
    }

    public void city() {
        System.out.println("普通的城市");
    }
}

荷兰地址类

java 复制代码

public class DutchAddress {
    public void straat() {}

    public void postcode() {}

    public void plaats() {}
}

荷兰地址适配器类

java 复制代码

public class DutchAddressAdapter extends DutchAddress {
    private Address address;

    public DutchAddressAdapter(Address address) {
        this.address = address;
    }

    public void straat() {
        address.street();
    }

    public void postcode() {
        address.zip();
    }

    public void plaats() {
        address.city();
    }
}

演示类

java 复制代码

public class Test {
    public static void main(String[] args) {
        Address addr = new Address();
        DutchAddress addrAdapter = new DutchAddressAdapter(addr);
        System.out.println("the DutchAddress");
        testDutch(addrAdapter);
    }

    private static void testDutch(DutchAddress addr) {
        addr.straat();
        addr.postcode();
        addr.plaats();
    }
}
