Given the following code snippet: ArrayList students=fp.readNamesAndCreateObjects("D:\\AAUJ\\AAA\\StudentNames.txt", "student");

HashMap studentsHashMap=fp.copyFromArrayListToHashMap(students);

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

{

System.out.println("Key = " + entries.getKey() + " , Value = " + entries.getValue());

}

Which of the following reflects a valid definition (signature and behavior) for the copyFromArrayListToHashMap

a.

default HashMap copyFromArrayListToHashMap(ArrayList objects)

{

HashMap result=new HashMap<>();

for(int i=0;i

{

result.put(i, objects.get(i));

}

return result;

}

b.

default Student copyFromArrayListToHashMap(ArrayList objects)

{

HashMap result=new HashMap<>();

for(int i=0;i

{

result.put(i, objects.get(i));

}

return result;

}

c.

default HashMap copyFromArrayListToHashMap(ArrayList objects)

{

HashMap result=new HashMap<>();

for(int i=0;i

{

result.put(i, objects.get(i));

}

return result;

}

d.

default HashMap copyFromArrayListToHashMap(ArrayList objects)

{

HashMap result=new HashMap<>();

for(int i=0;i

{

result.put(i, objects.get(i));

}

return result;

}
