Java 实现回调
package callbackexample;
public interface ICallBack {
//需要回调的方法 public void postExec();
} package callbackexample;
public class FooBar {
//组合聚合原则 private ICallBack callBack;
public void setCallBack(ICallBack callBack)
{ this.callBack = callBack;
doSth();
} public void doSth() { callBack.postExec();
} } package callbackexample;
public class Test {
public static void main(String[] args)
{ FooBar foo = new FooBar();
foo.setCallBack(new ICallBack()
{ public void postExec() {
System.out.println("在Test类中实现但不能被Test的对象引用,而由FooBar对象调用");
} }); } }
补充：软件开发 , Java ,
