  - toString
```
public  toString()
```
    Returns the values of the tuple, separated by commas, enclosed in parenthesis. Example: ("Ace", "Spades").
    
    Overrides:
    
    in class
  - extendDescription
```
protected void  builder)
```
    Overriden in subclasses to write additional values into the description.
    
    Parameters:
    
    builder -
  - equals
```
public boolean  obj)
```
    Compares this Tuple to another object. Equality is defined by: other object is not null, is same class as this Tuple, and all values are themselves equal.
    
    Overrides:
    
    in class
  - hashCode
```
public int hashCode()
```
    Returns a hash code value for the tuple, based on its values.
    
    Overrides:
    
    in class
    
    Returns:
    
    a hash code value for this tuple.

  - isMatch
```
protected boolean  other)
```
    The heart of equals(Object); the other object is the same class as this object.
    
    Parameters:
    
    other - other tuple to compare
    
    Returns:
    
    true if all values stored in tuple match
