use the IN300_Dataset2.txt file (https://kapextmediassl-a.akamaihd.net/IST/IN300/IN300_1905A/IN300_Dataset2.txt)
Write a Java program that:
A. Reads the text file.
B. Using that data, create a two-dimensional array that is 2,500 rows by 100 columns.
C. Slice the two-dimensional array using a starting column index of 2 and an ending column index of 5. Print the results of the arrays and slice.
