I'm currently working on an assignment for my
Java class. I have it finished, but can't seem to figure out why certain parts aren't working. The products portion of it is flawless, but the other 3 - min/max, finding the twelves, and the grader seem to be messed up. I've been at this for a few days now with no luck. It would be great if someone could help me out. Here were the instructions...
Part 1
Write a program that will find the product of a collection of data values. The program should ignore all negative values and terminate when a zero value is encountered.
2.
Write a program to read in a collection of integer values, and find and print the index of the first occurrence and last occurence of the number 12. The program should print an index value of 0 if the number 12 is not found. The index is the sequence number of the data item 12. For example if the eighth data item is the only 12, then the index value 8 should be printed for the first and last occurrence.
3.
Write a program to find the minimum, maximum, and average values of a collection of data values. The number of data values is unspecified.
4.
Write a program to read in a collection of exam scores ranging in value from 0 to 100. The program should count and print the number of A's (90 to 100), B's (70 to 89), C's (50 to 69), D's (35 to 49) and F's (0 to 34). The program should also print each score and its letter grade. Use the following
test data:
63 75 72 72 78 67 80 63 0 90 89 43 59 99 82 12 100 75
Part 2
For the second part of your assignment you will want to create a seperate file call "RunMenu" or "RunMyPrograms". This file will contain the main method and will have a loop structure that will allow a user to choose what program they want to run.
1) Product no negatives
2) Find Twelve
3) Max Min Avg
4) Letter Grade
5) Exit
