Consider the Loops class. Compile and run the program. Each of the methods in the Loons class has a comment explaining what the method is intended to do. None of the methods work as intended. Please complete the following task: Directly under each of the methods loop20, loop30, loop40, loop50) and loop60) write three comments: The first comment should start with "PROBLEM" and it should detail what the method is doing that it should not be doing, or conversely, what the method is not doing that it should be doing. The second comment should start "DIAGNOSIS" and should explain why the method has the problem described in the first comment The third comment should start "CORRECTION" and should explain how the method can be corrected so that it works as intended. You may find that for most methods you will only need to write a sentence or two for each comment, some may take more work to document, but do not write more than five sentences for each comment Note that the first method in the Loops class, loop10. has been completed for you as an example.
