Compares its two arguments for order.
clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait
public int compare(Authenticator a1, Authenticator a2)
The implementor must ensure that sgn(compare(x, y)) == -sgn(compare(y, x)) for all x and y. (This implies that compare(x, y) must throw an exception if and only if compare(y, x) throws an exception.)
The implementor must also ensure that the relation is transitive: ((compare(x, y)>0) && (compare(y, z)>0)) implies compare(x, z)>0.
Finally, the implementer must ensure that compare(x, y)==0 implies that sgn(compare(x, z))==sgn(compare(y, z)) for all z.It is generally the case, but not strictly required that (compare(x, y)==0) == (x.equals(y)). Generally speaking, any comparator that violates this condition should clearly indicate this fact. The recommended language is "Note: this comparator imposes orderings that are inconsistent with equals."
a1- the first object to be compared.
a2- the second object to be compared.
ClassCastException- if the arguments' types prevent them from being compared by this Comparator.
