This problem is asking for me to write a method in the SentenceCounter class that will pass the test in the images above.

Counting Lower Case Letters The next piece of functionality we're going to build is a method that counts the number of lower case letters in our String. Here's the test: Make this compile and watch the @Test test go RED. As with counting public void testCountLower (0) blanks, countLowerCase() will assertEquals (15, scl.countLowerCase()); need to walk though the string. assertEquals (40, sc2.countLowerCase()); However, this time it must check to see if the character in the current position is a lower-case letter. Write the code to make this test go GREEN and then REFACTOR as appropriate per REFACTOR includes writing the javadoc comments for the tests
