桥接模式
- 把事物与具体的实现分开，就是进行解耦
定义一个接口
public interface Sourceable {
public void method();
}
实现类1
public class SourceSub1 implements Sourceable {
@Override
public void method() {
System.out.println("this is the first sub!");
}
}
实现类2
public class SourceSub2 implements Sourceable {
@Override
public void method() {
System.out.println("this is the second sub!");
}
}
桥接类
在这个桥接类里面进行，其他两个对象封装，实现调用
public abstract class Bridge {
private Sourceable source;
public void method(){
source.method();
}
public Sourceable getSource() {
return source;
}
public void setSource(Sourceable source) {
this.source = source;
}
}
调用类
public class MyBridge extends Bridge {
public void method(){
getSource().method();
}
}
测试类
public class BridgeTest {
public static void main(String[] args) {
Bridge bridge = new MyBridge();
/*调用第一个对象*/
Sourceable source1 = new SourceSub1();
bridge.setSource(source1);
bridge.method();
/*调用第二个对象*/
Sourceable source2 = new SourceSub2();
bridge.setSource(source2);
bridge.method();
}
}
