Class java.util.BitSet 

java.lang.Object
   |
   +----java.util.BitSet
public final class BitSet
extends Object
implements Cloneable
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
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

Parameters:
obj - the object to commpare with
Returns:
true if the objects are the same; false otherwise.
Overrides:
equals in class Object
