Why toString() method works differently between Array and ArrayList object in Java

Question

    String[] array = {\"a\",\"c\",\"b\"};
    ArrayList list = new ArrayList();
    list.add(\"a\");
    list.add(\"b\");
    list.add(\"         


        

Answer 1

This is the toString method call for ArrayList. But for Arrays you cant find such.

 /**
 * Returns a string representation of this collection.  The string
 * representation consists of a list of the collection's elements in the
 * order they are returned by its iterator, enclosed in square brackets
 * ("[]").  Adjacent elements are separated by the characters
 * ", " (comma and space).  Elements are converted to strings as
 * by {@link String#valueOf(Object)}.
 *
 * @return a string representation of this collection
 */
public String toString() {
    Iterator it = iterator();
    if (! it.hasNext())
        return "[]";

    StringBuilder sb = new StringBuilder();
    sb.append('[');
    for (;;) {
        E e = it.next();
        sb.append(e == this ? "(this Collection)" : e);
        if (! it.hasNext())
            return sb.append(']').toString();
        sb.append(',').append(' ');
    }
}
