```
public SynchronizedInt(int initialValue)
```
    Make a new SynchronizedInt with the given initial value, and using its own internal lock.
  - SynchronizedInt
```
public SynchronizedInt(int initialValue,
               Object lock)
```
    Make a new SynchronizedInt with the given initial value, and using the supplied lock.
- Method Detail
  - get
```
public final int get()
```
    Return the current value
  - set
```
public int set(int newValue)
```
    Set to newValue.
    
    Returns:
    the old value
  - commit
```
public boolean commit(int assumedValue,
             int newValue)
```
    Set value to newValue only if it is currently assumedValue.
    
    Returns:
    true if successful
  - swap
```
public int swap(SynchronizedInt other)
```
    Atomically swap values with another SynchronizedInt. Uses identityHashCode to avoid deadlock when two SynchronizedInts attempt to simultaneously swap with each other. (Note: Ordering via identyHashCode is not strictly guaranteed by the language specification to return unique, orderable values, but in practice JVMs rely on them being unique.)
    
    Returns:
    the new value
  - increment
```
public int increment()
```
    Increment the value.
    
    Returns:
    the new value
  - decrement
```
public int decrement()
```
    Decrement the value.
    
    Returns:
    the new value
  - add
```
public int add(int amount)
```
    Add amount to value (i.e., set value += amount)
    
    Returns:
    the new value
  - subtract
```
public int subtract(int amount)
```
    Subtract amount from value (i.e., set value -= amount)
    
    Returns:
    the new value
  - multiply
```
public int multiply(int factor)
```
    Multiply value by factor (i.e., set value *= factor)
    
    Returns:
    the new value
  - divide
```
public int divide(int factor)
```
    Divide value by factor (i.e., set value /= factor)
    
    Returns:
    the new value
  - negate
```
public int negate()
```
    Set the value to the negative of its old value
    
    Returns:
    the new value
  - complement
```
public int complement()
```
    Set the value to its complement
    
    Returns:
    the new value
  - and
```
public int and(int b)
```
    Set value to value & b.
    
    Returns:
    the new value
  - or
```

```
    Set value to value | b.
    
    Returns:
    the new value
  - xor
```
public int xor(int b)
```
    Set value to value ^ b.
    
    Returns:
    the new value
