array

[thrilok nath]

Is it possible to create arrays of length zero?
Select the one correct answer.
a.Yes, you can create arrays of any type with length zero.
b.Yes, but only for primitive data types.
c.Yes, but only for arrays of object references.
d.No, you cannot create zero-length arrays, but the main() method may be passed a zero-length array of String references when no program arguments are specified.
e.No, it is not possible to create arrays of length zero in Java.

Welcome to JavaRanch!

The best way to learn (especially when preparing for the SCJP exam) is to write lots of test code. Have you tried to create primitive/object arrays of length zero and verify their length?

Well said, Marc !

Thrilok, I've tried out this and the correct answer is 'a'.
You can create an array of any type, of length 0.

A is correct!

public class Test090401 {
public static void main (String [] args) {
int[] arr1 = new int[0];
System.out.println("arr1.length: " + arr1.length);
Object[] arr2 = new Object[0];
System.out.println("arr2.length: " + arr2.length);
}
}

Output is:

arr1.length: 0
arr2.length: 0
