An array of ZERO length can be defined in JAVA. It can be declared in the following ways:- > int arrInt = new int[0];> int arrInt = new Int[]{};But this array will be unchangable.Usage:- Suppose, a method is returning an array of any type. Now under some condition, the method may return NULL. So instead of returning NULL, an array of Zero length can be returned. This will make the method more optimized as returning NULL to an array reference is not at all adviceable.
