Examples of java.util.BitSet

java.util.BitSet
This class implements a vector of bits that grows as needed. Each component of the bit set has a boolean value. The bits of a BitSet are indexed by nonnegative integers. Individual indexed bits can be examined, set, or cleared. One BitSet may be used to modify the contents of another BitSet through logical AND, logical inclusive OR, and logical exclusive OR operations.
By default, all bits in the set initially have the value false.
Every bit set has a current size, which is the number of bits of space currently in use by the bit set. Note that the size is related to the implementation of a bit set, so it may change with implementation. The length of a bit set relates to logical length of a bit set and is defined independently of implementation.
Unless otherwise noted, passing a null parameter to any of the methods in a BitSet will result in a NullPointerException.
A BitSet is not safe for multithreaded use without external synchronization. @author Arthur van Hoff @author Michael McCloskey @author Martin Buchholz @version 1.67, 04/07/06 @since JDK1.0
