### Question:
BiUtil { public static boolean isMoreThan(BigInteger valueA, BigInteger valueB) { return valueA.compareTo(valueB) > 0; } private  BiUtil(); static boolean isZero(BigInteger value); static boolean isEqual(BigInteger valueA, BigInteger valueB); static boolean isNotEqual(BigInteger valueA, BigInteger valueB); static boolean isLessThan(BigInteger valueA, BigInteger valueB); static boolean isMoreThan(BigInteger valueA, BigInteger valueB); static BigInteger sum(BigInteger valueA, BigInteger valueB); static BigInteger toBi(long data); static boolean isPositive(BigInteger value); static boolean isCovers(BigInteger covers, BigInteger value); static boolean isNotCovers(BigInteger covers, BigInteger value); static boolean exitLong(BigInteger value); static boolean isIn20PercentRange(BigInteger first, BigInteger second); static BigInteger max(BigInteger first, BigInteger second); static int addSafely(int a, int b);  }### Answer:
@Test public void isMoreThan() { Assert.assertTrue(BiUtil.isMoreThan(BigInteger.ONE, BigInteger.ZERO)); }
