Which of the following statements about interfaces in Java is correct? Select one: Interfaces cannot inherit from another interface. Using the keyword "extends," inheritance relationships can be defined both between classes and between interfaces. Using the keyword "implements," inheritance relationships can be defined both between classes and between interfaces. Interfaces can inherit only from one other interface.

Which of the following statements is wrong? Select one: With the exception of constants, no attributes may be specified in interfaces. The class must implement at least one method for each interface. The class must implement all methods for each interface or it must be declared abstract. With the help of the keyword "implements" a class can indicate which interfaces it implements.

Which of the following statements on the modeling of interfaces in UML is wrong? Select one: A dotted arrow with an open tip and the stereotype << abstract>> points from the used interface to the using class. The stereotype << interface>> defines an interface. The interface does not contain attributes. A dotted arrow with a closed tip points from the implementing class to the interface.
