Use Scanner class to read a file of integers and find the average of each line and add into a 1D array of size equal to number of lines. There will be 5 lines with 5 integers per line seperated by spaces in the input file.
Need to have two methods which is not dependent on any static/instance variable:
- public static int arr readIntAndInsertArr(String filename) - receives a file name as input, reads it, uses findAverage to find average of a line.
- public static int findAverage(String line) - finds average of a String of integers seperated by spaces.
Example Input file contents
1 2 3 4 5
3 4 5 8 9
6 7 8 9 7
4 5 6 7 8
22 33 44 5 6
You need to add the average of each line into an array. For example, arr will be 3, which is calculated as (1+2+3+4+5)/5.
Since there are 5 lines array size should be 5.
ALL THE BEST !!!
