Method Detail

compare

public int compare(BigInteger x,
                   BigInteger y)

Compares its two arguments for order, which is reverse than the usual order. Returns a negative integer, zero, or a positive integer as the first argument is greater than, equal to, or less than the second.

Specified by:

compare in interface Comparator<BigInteger>

Parameters:

x - the first number to be compared

y - the second number to be compared

Returns:

-1 if x>y, 0 if x==y, or 1 if x<y
