Interface inheritance

[Gaurav Pavan Kumar Jain]

. public interface A {
2. String DEFAULT_GREETING = �Hello World�;
3. public void method1();
4. }
A programmer wants to create an interface called B that has A as its
parent. Which interface declaration is correct?
A. public interface B extends A { }
B. public interface B implements A {}
C. public interface B instanceOf A {}
D. public interface B inheritsFrom A { }

Answer is B but i think it should be A

Hi,

The answer for this cannot be B. Interface implements interface is never legal.

implements

keyword itself says that the class which is implementing the interface will give the implementtion for all the methods in the interface(unless the class is a abstract class).

The answer is Only "A"
<Interface> extends <interface>
<class> implements <interface>
you've to see the JSL 9.1.1
B is illegal
