public int compare(java.lang.Comparable<T> o1,
                   java.lang.Comparable<T> o2)
```
    Compare the two Comparable arguments. This method is equivalent to:
    ((Comparable)o1).compareTo(o2)
    Specified by:
    
    compare in interface java.util.Comparator<T extends java.lang.Comparable<T>>
    
    Parameters:
    
    o1 - the first object
    
    o2 - the second object
    
    Returns:
    
    result of comparison
    
    Throws:
    
    java.lang.NullPointerException - when o1 is null, or when ((Comparable)o1).compareTo(o2) does
    
    java.lang.ClassCastException - when o1 is not a Comparable, or when ((Comparable)o1).compareTo(o2) does
