桥接模式：将抽象化与实现化解耦，使得二者可以独立变化
代码：
public interface Sourceable {
public void method();
}
public class SourceSub1 implements Sourceable {
@Override
public void method() {
System.out.println("this is the first sub!");
}
}
public class SourceSub2 implements Sourceable {
@Override
public void method() {
System.out.println("this is the second sub!");
}
}
将 SourceSub1 SourceSub2 统一归桥调度
public abstract class Bridge {
private Sourceable source; //遵循接口的对象
public void method(){
source.method();
}
public Sourceable getSource() {
return source;
}
public void setSource(Sourceable source) {
this.source = source;
}
}
public class MyBridge extends Bridge {
public void method(){
getSource().method();
}
}
使用
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();
}
}
