怎么用object定义接口啊

Answer 1

比如常用的接口文件书写格式：public interface Dao { public int save(Object object);//参数为Object public int deleteObject(String objectName, Object... condition);//参数为不固定个数的Object public Object queryBean(String hql);//返回值为Object public List<?> queryBeans(String objectName, int begin, int num);//泛型数组的返回值（包含Object）}

Answer 2

什么意思？接口不是public interface xxx{}么
