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:
- get (int index)
- set (int index)
- clear (int index)
- flip (int index)
