Be sure to include functional code demonstrating each of the methods required. Even if the requirements don't specify how to exercise the code, be sure to include at least a line of code that tests the method. All code submitted this semester must be accompanied by a program, with a main$($String$[])$ method, that shows the code running. You can't write code without running it as you go$!$

It's fine to place all of these methods in the same Java file. Please be sure to name your methods clearly and place a comment above each method that indicates which problem it is meant to solve.

Custom Program: Write a static method that accepts a double value and returns a grade with plus$/$minus as a String value. Use the grade scale found in the syllabus for this method implementation. Don't do any error checking. Assume that any value over $100$ returns an A and any value under $60$ returns an F$.$

Example: Given the input $89\mathrm{.}1$ the method would return B$+.$
