Method Summary

Methods
Modifier and Type	Method and Description
`boolean`	`add(int value)` Add an integer to the set
`void`	`clear()` Clear the contents of the IntSet (making it an empty set)
`boolean`	`contains(int value)` Determine whether a particular integer is present in the set
`boolean`	`containsAll(IntSet other)` Test if this set is a superset of another set
`IntSet`	`copy()` Create a copy of this IntSet that leaves the original unchanged.
`IntSet`	`except(IntSet other)` Form a new set that is the difference of this set and another set.
`IntSet`	`intersect(IntSet other)` Form a new set that is the intersection of this IntSet and another.
`boolean`	`isEmpty()` Determine if the set is empty
`IntIterator`	`iterator()` Get an iterator over the values
`IntSet`	`mutableCopy()` Create a copy of this IntSet that contains the same set of integers.
`boolean`	`remove(int value)` Remove an integer from the set
`int`	`size()` Get the number of integers in the set
`IntSet`	`union(IntSet other)` Form a new set that is the union of this IntSet and another.

- Method Detail
  - copy
```
IntSet copy()
```
    Create a copy of this IntSet that leaves the original unchanged.
    
    Returns:
    an IntSet containing the same integers. The result will not necessarily be the same class as the original. It will either be an immutable object, or a newly constructed object.
  - mutableCopy
```
IntSet mutableCopy()
```
    Create a copy of this IntSet that contains the same set of integers.
    
    Returns:
    an IntSet containing the same integers. The result will not necessarily be the same class as the original. It will always be a mutable object
  - clear
```
void clear()
```
    Clear the contents of the IntSet (making it an empty set)
  - size
```
int size()
```
    Get the number of integers in the set
    
    Returns:
    the size of the set
  - isEmpty
```
boolean isEmpty()
```
    Determine if the set is empty
    
    Returns:
    true if the set is empty, false if not
  - contains
```
boolean contains(int value)
```
    Determine whether a particular integer is present in the set
    
    Parameters:
    value - the integer under test
    
    Returns:
    true if value is present in the set, false if not
  - remove
```
boolean remove(int value)
```
    Remove an integer from the set
    
    Parameters:
    value - the integer to be removed
    
    Returns:
    true if the integer was present in the set, false if it was not present
  - add
```
boolean add(int value)
```
    Add an integer to the set
    
    Parameters:
    value - the integer to be added
    
    Returns:
    true if the integer was added, false if it was already present
  - iterator
```
IntIterator iterator()
```
    Get an iterator over the values
    
    Returns:
    an iterator over the integers in the set
  - union
```
IntSet union(IntSet other)
```
    Form a new set that is the union of this IntSet and another. The result will either be an immutable object, or a newly constructed object.
    
    Parameters:
    other - the second set
    
    Returns:
    the union of the two sets
  - intersect
```
IntSet intersect(IntSet other)
```
    Form a new set that is the intersection of this IntSet and another. The result will either be an immutable object, or a newly constructed object.
    
    Parameters:
    other - the second set
    
    Returns:
    the intersection of the two sets
  - except
```
IntSet except(IntSet other)
```
    Form a new set that is the difference of this set and another set. The result will either be an immutable object, or a newly constructed object.
    
    Parameters:
    other - the second set
    
    Returns:
    the intersection of the two sets
  - containsAll
```
boolean containsAll(IntSet other)
```
    Test if this set is a superset of another set
    
    Parameters:
    other - the other set
    
    Returns:
    true if every integer in the other set is also present in this set
