The following program can be done completely in the main method.

Create a Scanner to read from a file, after requesting the name of the file. You can read in the names from integerlist.txt in the homework tab for Programs in Assignment 5.

Write a program that reads in a set of integers from the file one by one and places them into an ArrayList from least to greatest. Print out the list in order from least to greatest.

Hints:

Check to make sure that the file is not empty.

You will need to use a Wrapper class.

Read the first element into the ArrayList.

Read in additional integers until you reach the end of the file, inserting each number into the array list as you read it in. This is a true insertion sorting.
