NOTE (the code runs for me and i get the output
below) but, i get this error below
(Failed: Rendered summary does not have the expected number of
lines ==> expected: <6> but was: <1>)
Please edit my code for
(studentresultsummary.java) only,
(GradeUtils.java is already completed but feel
free if you want to make some changes)
Output
**********************************************************************
HD: 10 (13.0%)
D: 9 (11.7%)
C: 3 (3.9%)
P: 14 (18.2%)
Z: 41 (53.2%)
Top student: Michael Riley with 97.4% (HD)

INSTRUCTIONS
We've provided a skeleton of a StudentResultSummary class with
the following methods for you to implement:
add - for adding a single StudentResult to the summary
addAll - for adding multiple StudentResult to the summary
reset - for clearing all data from the summary
renderToString - for printing out the summary, in the same
format as described above.
It is entirely up to you to figure out how to code up these
methods, and to design any other aspects of the class (e.g. fields,
additional helper methods) that are needed to make it work.
Some minor things you will need to account for to pass the
automated tests:
The rendered summary needs look exactly like the example
provided above, including its use of whitespace and punctuation,
and the number of decimal points included in percentage values.
If the summary is rendered before any data is added to it, then
it should render as "No results to show" (without any
punctuation).
If there are multiple students who all achieved the same high
mark, your summary should always show the name of the first student
who achieved the top mark (based on the order that student results
are added to the summary).
