Method outputBarChart
Method outputBarChart in Fig. 7.18 is nearly identical to the one in Fig. 7.14. However, to output the overall grade distribution for a whole semester, the method here uses nested enhanced for statements (lines 107–111) to create the one-dimensional array frequency based on all the grades in the two-dimensional array. The rest of the code in each of the two outputBarChart methods that displays the chart is identical.
