Given the following code snippet:

default > E getMaxObject(HashMap objects) {

E max=objects.get(0);

for(HashMap.Entry entries: objects.entrySet())

{

if(entries.getValue().compareTo(max) > 0) max= entries.getValue();

}

return max;

}

return max;

}

a.

The class to which the object E belong must be of type Double

b.

All of these

c.

The class to which the object E belongs must implement Comparable interface

d.

The class to which the object E belongs must implement Comparable interface

Choose the correct signature for the below method. It must take a HashMap as input and return an Object of Type E as output:

default ........................................................................ getMaxObject(........................... objects)

{

E max=objects.get(0);

for(HashMap.Entry entries: objects.entrySet())

{

if(entries.getValue().compareTo(max) > 0) max= entries.getValue();

}

return max;

}

a.

default E getMaxObject(HashMap objects)

b.

default > E getMaxObject(HashMap objects)

c.

default > T getMaxObject(HashMap objects)

d.

None of these
