Question

Consider the following code snippet:
public static <E> void print(E[] a)
{
for (int i = 0; i < a.length; i++)
{
System.out.println(a[i] + " ");
}
}
int[] a = {3,6,5,7,8,9,2,3};
print(makeArray(a));
Assume that the method call to print(makeArray(a)) works correctly by printing the int array a.Which of the following headers for the makeArray method will make this possible?
i.public static Integer[] makeArray(int[] a)
II.public static E[] makeArray(int[] a)
III.public static Integer[] makeArray(E[] a)
A)II and III only
B)I and III only
C)I and II only
D)I only

Quizplus · Accepted Answer

The correct header for the makeArray method is "public static Integer[] makeArray(int[] a)" because it converts a primitive int array to an Integer array, which is necessary for the generic print method to work. Options II and III are incorrect because they either use a generic type E that is not defined in the context of makeArray or attempt to convert a generic array E[] to an Integer array, which is not compatible with the provided int array.
