Java BitSet

     

In Java, the BitSet is a class that is available in the java.util package.  

The BitSet object represents a vector of bits whose size can grow according to the requirement. Every bit in the bit set has a boolean value true/false.
The bits in a BitSet are indexed by the positive integers only.  All bits in the bit set initially have the false value, by default.

User can can set or clear the individual indexed bits. 

Logical AND, logical inclusive OR, and logical exclusive OR operations can be used by one BitSet to modify the contents of another BitSet.

The BitSet class in the java.util package provides methods to access a given bit in the array with an index:

1. get (int index)
2. set (int index)
3. clear (int index)
4. flip (int index)
