this would fail this test

assertEquals(
"apples, pears# and bananas\ngrapes\nbananas",
StripComments.stripComments( "apples, pears# and bananas\ngrapes\nbananas !$apples", new String[] { "#$", "!$" } )
);

The author has provided a function, MorseCode.get(), to retrieve the codes, but if you provide a code that function doesn't know it returns null.

When summit my solution I get 4 messages like:

./src/test/java/DescendingOrderTest.java:9: error: unreported exception Exception; must be caught or declared to be thrown
assertEquals(0, DescendingOrder.sortDesc(0));

But in my tests, I test for this very same case plus:

		assertEquals(0, DescendingOrder.sortDesc(0));
		assertEquals(2111111111, DescendingOrder.sortDesc(1111111112));
		assertEquals(54421, DescendingOrder.sortDesc(21445));
		assertEquals(654321, DescendingOrder.sortDesc(145263));
		assertEquals(987654321, DescendingOrder.sortDesc(123456789));

and they all pass. ????

Any tips? Please .....
