question: public void testCompareToZeroNeg ( ) { byte bBytes [ ] = { 12 , 56 , 100 , - 2 , - 76 , 89 , 45 , 91 , 3 , - 15 , 35 , 26 , 3 , 91 } ; int bSign = - 1 ; BigInteger aNumber = BigInteger . ZERO ; BigInteger bNumber = new BigInteger ( bSign , bBytes ) ; assertEquals ( 1 , aNumber . compareTo ( bNumber ) ) ; }
target:  compareTo(BigInteger a). Compare ZERO to a negative number.
