    set - a bit set
  - or
```
public void or(LongValueBitSet set)

    Performs a logical OR of this bit set with the bit set argument. This bit set is modified so that a bit in it has the value true if and only if it either already had the value true or the corresponding bit in the bit set argument has the value true.
    
    Parameters:
    
    set - a bit set
  - xor
```
public void xor(LongValueBitSet set)
```
    Performs a logical XOR of this bit set with the bit set argument. This bit set is modified so that a bit in it has the value true if and only if one of the following statements holds:
    - The bit initially has the value true, and the corresponding bit in the argument has the value false.
    - The bit initially has the value false, and the corresponding bit in the argument has the value true.
    Parameters:
    
    set - a bit set
  - andNot

    Since:
    
    1.2
  - hashCode
```
public int hashCode()
```
    Returns the hash code value for this bit set. The hash code depends only on which bits are set within this BitSet.
    The hash code is defined to be the result of the following calculation:
```
 
 public int hashCode() {
     long h = 1234;
     long[] words = toLongArray();
     for (int i = words.length; --i >= 0; )
         h ^= words[i] * (i + 1);
     return (int)((h >> 32) ^ h);
 }
```
    Note that the hash code changes if the set of bits is altered.
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    the hash code value for this bit set
  - size
```
public int size()
```
    Returns the number of bits of space actually in use by this BitSet to represent bit values. The maximum element in the set is the size - 1st element.
    
    Returns:
    
    the number of bits currently in this bit set
  - equals
```
public boolean equals(Object obj)
```
    Compares this object against the specified object. The result is true if and only if the argument is not null and is a Bitset object that has exactly the same set of bits set to true as this bit set. That is, for every nonnegative int index k,
```
((BitSet)obj).get(k) == this.get(k)
```
    must be true. The current sizes of the two bit sets are not compared.
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the object to compare with
    
    Returns:
    
    true if the objects are the same; false otherwise
    
    See Also:
    
    size()
  - toString
```
public String toString()
```
    Returns a string representation of this bit set. For every index for which this BitSet contains a bit in the set state, the decimal representation of that index is included in the result. Such indices are listed in order from lowest to highest, separated by ", " (a comma and a space) and surrounded by braces, resulting in the usual mathematical notation for a set of integers.
    Example:
```
 BitSet drPepper = new BitSet();
```
    Now drPepper.toString() returns "{}".
```
 drPepper.set(2);
```
    Now drPepper.toString() returns "{2}".
```
 drPepper.set(4);
 drPepper.set(10);
```
    Now drPepper.toString() returns "{2, 4, 10}".
    Overrides:
    
    toString in class Object
    
    Returns:
    
    a string representation of this bit set
  - stream
```
public IntStream stream()
```
    Returns a stream of indices for which this BitSet contains a bit in the set state. The indices are returned in order, from lowest to highest. The size of the stream is the number of bits in the set state, equal to the value returned by the cardinality() method.
    The bit set must remain constant during the execution of the terminal stream operation. Otherwise, the result of the terminal stream operation is undefined.
    
    Returns:
    
    a stream of integers representing set indices
