Constructor

	BitSet() Creates a new bit set.
	BitSet(int nbits) Creates a bit set whose initial size is large enough to explicitly represent bits with indices in the range 0 through nbits-1 .
	BitSet(long[] words) Creates a bit set using words as the internal representation.

Method

void	and(BitSet set) Performs a logical AND of this target bit set with the argument bit set.
void	andNot(BitSet set) Clears all of the bits in this BitSet whose corresponding bit is set in the specified BitSet .
int	cardinality() Returns the number of bits set to true in this BitSet .
void	clear(int bitIndex) Sets the bit specified by the index to false .
void	clear() Sets all of the bits in this BitSet to false .
void	clear(int fromIndex, int toIndex) Sets the bits from the specified fromIndex (inclusive) to the specified toIndex (exclusive) to false .
Object	clone() Cloning this BitSet produces a new BitSet that is equal to it.
boolean	equals(Object obj) Compares this object against the specified object.
void	flip(int bitIndex) Sets the bit at the specified index to the complement of its current value.
void	flip(int fromIndex, int toIndex) Sets each bit from the specified fromIndex (inclusive) to the specified toIndex (exclusive) to the complement of its current value.
boolean	get(int bitIndex) Returns the value of the bit with the specified index.
BitSet	get(int fromIndex, int toIndex) Returns a new BitSet composed of bits from this BitSet from fromIndex (inclusive) to toIndex (exclusive).
int	hashCode() Returns the hash code value for this bit set.
boolean	intersects(BitSet set) Returns true if the specified BitSet has any bits set to true that are also set to true in this BitSet .
boolean	isEmpty() Returns true if this BitSet contains no bits that are set to true .
int	length() Returns the "logical size" of this BitSet : the index of the highest set bit in the BitSet plus one.
int	nextClearBit(int fromIndex) Returns the index of the first bit that is set to false that occurs on or after the specified starting index.
int	nextSetBit(int fromIndex) Returns the index of the first bit that is set to true that occurs on or after the specified starting index.
void	or(BitSet set) Performs a logical OR of this bit set with the bit set argument.
int	previousClearBit(int fromIndex) Returns the index of the nearest bit that is set to false that occurs on or before the specified starting index.
int	previousSetBit(int fromIndex) Returns the index of the nearest bit that is set to true that occurs on or before the specified starting index.
void	set(int bitIndex) Sets the bit at the specified index to true .
void	set(int bitIndex, boolean value) Sets the bit at the specified index to the specified value.
void	set(int fromIndex, int toIndex) Sets the bits from the specified fromIndex (inclusive) to the specified toIndex (exclusive) to true .
void	set(int fromIndex, int toIndex, boolean value) Sets the bits from the specified fromIndex (inclusive) to the specified toIndex (exclusive) to the specified value.
int	size() Returns the number of bits of space actually in use by this BitSet to represent bit values.
byte[]	toByteArray() Returns a new byte array containing all the bits in this bit set.
long[]	toLongArray() Returns a new long array containing all the bits in this bit set.
String	toString() Returns a string representation of this bit set.
BitSet	valueOf(long[] longs) Returns a new bit set containing all the bits in the given long array.
BitSet	valueOf(LongBuffer lb) Returns a new bit set containing all the bits in the given long buffer between its position and limit.
BitSet	valueOf(byte[] bytes) Returns a new bit set containing all the bits in the given byte array.
BitSet	valueOf(ByteBuffer bb) Returns a new bit set containing all the bits in the given byte buffer between its position and limit.
void	xor(BitSet set) Performs a logical XOR of this bit set with the bit set argument.
