Class java.util.BitSet 

java.lang.Object
   |
   +----java.util.BitSet
public final class BitSet
extends Object
implements Cloneable, Serializable
A set of bits. The set automatically grows as more bits are needed.

Constructor Index

o BitSet()
Creates an empty set.
o BitSet(int)
Creates an empty set with the specified size.

Method Index

o and(BitSet)
Logically ANDs this bit set with the specified set of bits.
o clear(int)
Clears a bit.
o clone()
Clones the BitSet.
o equals(Object)
Compares this object against the specified object.
o get(int)
Gets a bit.
o hashCode()
Gets the hashcode.
o or(BitSet)
Logically ORs this bit set with the specified set of bits.
o set(int)
Sets a bit.
o size()
Calculates and returns the set's size in bits.
o toString()
Converts the BitSet to a String.
o xor(BitSet)
Logically XORs this bit set with the specified set of bits.

Constructors

o BitSet 
 public BitSet()
Creates an empty set.

o BitSet 
 public BitSet(int nbits)
Creates an empty set with the specified size.

Parameters:
nbits - the size of the set

Methods

o set 
 public void set(int bit)
Sets a bit.

Parameters:
bit - the bit to be set
o clear 
 public void clear(int bit)
Clears a bit.

Parameters:
bit - the bit to be cleared
o get 
 public boolean get(int bit)
Gets a bit.

Parameters:
bit - the bit to be gotten
o and 
 public void and(BitSet set)
Logically ANDs this bit set with the specified set of bits.

Parameters:
set - the bit set to be ANDed with
o or 
 public void or(BitSet set)
Logically ORs this bit set with the specified set of bits.

Parameters:
set - the bit set to be ORed with
o xor 
 public void xor(BitSet set)
Logically XORs this bit set with the specified set of bits.

Parameters:
set - the bit set to be XORed with
o hashCode 
 public int hashCode()
Gets the hashcode.

Overrides:
hashCode in class Object
o size 
 public int size()
Calculates and returns the set's size in bits. The maximum element in the set is the size - 1st element.

o equals 
 public boolean equals(Object obj)
Compares this object against the specified object.

Parameters:
obj - the object to compare with
Returns:
true if the objects are the same; false otherwise.
Overrides:
equals in class Object
o clone 
 public Object clone()
Clones the BitSet.

Overrides:
clone in class Object
o toString 
 public String toString()
Converts the BitSet to a String.

Overrides:
toString in class Object
