 # Java Programming Problems

## Question

This lab requires writing 4 methods and the main program that calls all four methods. The methods should do the following:

1. Ask a user to enter 10 numbers and return the max of them.

2. Accept the number returned by the first method and round it down to the closest number divisible by 10. e.g., 37.6 is rounded to 30, -45 is rounded to -50, 10 is rounded to 10.

3. Accept the number returned by the second method and use switch statement to convert it to a letter "grade".
If the number is positive, then convert it to a letter grade as usual:
grade >= 90 is A; grade less than 60 is F, etc.
If the number is negative, then assign letter N.

4. Print the statement of the form:
The letter assigned to the number 84.6 when rounded to 80 is B.
In the previous example, 84.6 should be replaced by the number returned by the first method, 80 should be replaced by the number returned by the second method, and B should be replaced by the letter returned by the third method.
