When to use an array of size zero ?

Question

Java provides the facility to have an array of size zero. But I have never seen anybody using this. Do we have any scenario when this zero size array can be used.
Thanks

Answer 1

It allows me to do that, so it perfectly makes sense. Does it makes for you too ?
package unitTesting;
import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertTrue;
import java.util.ArrayList;
import java.util.Collection;
import org.junit.Before;
import org.junit.Test;
public class Rdtf
     private Collection<Object> collection;
     @Before
     public void setUp() {
          collection = new ArrayList<Object>();
     @Test
     public void testEmptyCollection()
          assertTrue(collection.isEmpty());
     @Test
     public void testOneItemCollection()
          collection.add("itemA");
          assertEquals(1, collection.size());
     @Test(expected=IndexOutOfBoundsException.class)
     public void testIndexOutOfBoundsException() {
          ArrayList<Object> emptyList = new ArrayList<Object>();
          Object o = emptyList.get(0);
     @Test
    public void testIndexOutOfBoundsExceptionNotRaised()
        throws IndexOutOfBoundsException {
        ArrayList<Object> emptyList = new ArrayList<Object>();
        Object o = emptyList.get(0);
}
