Statistics Lab - Loop/ File IO NEED HELP!
I'm desperate to try and solve this. I forgot to do this lab during mid semester in my computer science class and for some reason i'm drawing complete blanks. This is the last lab I need to complete for full credit. I put in some of the basic variables but really need help completing this.

I don't have the text files with me.

Code Java:

```/* * Create a program that will calculate the min, max and average from a * data set(s). The purpose of the lab is to implement a loop construct * along with the ability to perform file I/O. * 1) Place C4L2_Data1.txt, C4L2_Data2.txt, and C4L2_Data3.txt in the * root directory of your project. These are your input files. * 2) Each file has a list of numbers which is a combination of * integer and floating point values. * 3) Each file has the same values, but in different order. * 4) Since it is likely you wouldn't know the count of values in an input * file I suggest you use the while or do-while loop. * 5) Your program should read the data line-by-line evaluating each value * to determine if it is the min or max while also accumulating the total * which will be used to calculate the avergage upon reading all values. * 6) After you execute your program using C4L2_Data1.txt, run it again * using the other two input files. * 7) The purpose of having the same data amongst three files is to test * the logic of your program to handle the case(s) where the min and max * could be anywhere in the file. * 8) After you execute your program with the three files you should always * obtain the same min, max, and average. If your results differ between * the input files then you have a logical error in your program */   import java.io.File; import java.util.Scanner; import java.text.DecimalFormat;   public class C4L2_Statistics { public static void main(String[] args) throws Exception{ double num; //Temporary var representing a single value from the file double min; //The minimum value in the file double max; //The maximum value in the file double average; //The average of the values int count = 0; //Keeps track of the number of values in the file double total = 0; //The accumulator DecimalFormat formatter = new DecimalFormat("#,##0.00");             System.out.println("min="); System.out.println("max="); System.out.println("average=");   } }```
