toString

Returns a string representation of this bit set. For every index for which this BitSet contains a bit in the set state, the decimal representation of that index is included in the result. Such indices are listed in order from lowest to highest, separated by ", " (a comma and a space) and surrounded by braces, resulting in the usual mathematical notation for a set of integers.

Example:

BitSet drPepper = new BitSet();

Now drPepper.toString() returns "{}".

drPepper.set(2);

Now drPepper.toString() returns "{2}".

drPepper.set(4);
drPepper.set(10);

Now drPepper.toString() returns "{2, 4, 10}".
