I need to write a program that asks for the file name of a text document of number and then calculates average, median, etc., from this data set. I have written the program so
Your program needs to know the full path in order to find the file. It isn't just searching your computer for the file "inputValues2.txt". It needs to know exactly how to get there. If you wanted to, you could move the file into your project folder, and then you would just be able to write "inputValues2.txt" to access it. I normally create a folder called "res" in my project folder, and then let's say I am trying to create an image:
Image i = new Image("res/img.png");
