Lab9B: Lab9A, but now with more math For this exercise you will be writing a program that will be building upon the previous program. So please make a new class file, copy, and rename the code you have already written for Lab9A. Please also remember to rename the file and (and in the case of Java and C# students) class name to Lab9B. For this exercise, please calculate two values from all of the numbers in the two dimensional array. The first value should be the sum of all numbers in the array. This should be stored in a separate “int" variable that is created outside the nested FOR loops. The second value should be the total average of all numbers in the Array. This should be stored in a separate “float" variable, also outside the nested FOR loop structure. So, in short: Display the sum of the values in the array Then display the average of the values in the array
