Java Application – MinFinder

Create a Java application named MinFinder.java to take a given 2 dimensional array and find the minimum value for each row, column, and the whole array.

A text file named Array.txt contains a 10×10 grid of value for the array:
8.63,1.45,5.56,2.19,9.60,3.79,2.19,2.44,3.25,9.86
4.30,4.53,2.81,8.58,7.09,8.79,1.66,3.18,8.81,1.21
1.99,8.24,7.97,6.30,3.28,8.56,5.14,7.82,8.94,3.33
9.57,8.76,9.04,4.47,6.05,7.71,9.66,8.66,1.42,6.76
9.61,3.84,3.25,3.26,3.66,3.46,3.74,1.72,5.50,6.53
3.21,7.92,3.94,9.35,6.53,4.48,6.67,7.81,7.11,2.14
5.87,2.34,1.05,8.79,6.94,8.81,4.77,4.20,6.92,6.43
8.41,6.74,2.46,3.94,10.00,4.65,8.02,7.56,2.87,6.99
8.92,3.84,4.47,9.82,2.04,3.87,8.04,1.38,7.24,1.35
2.03,1.53,1.62,6.67,7.29,7.28,2.08,6.54,6.31,9.13

Notice the values are separated by commas. Your application should read the values into a two dimensional array.

After the array is created, find the lowest value for each row, column, and the whole grid.

Use modular programming, this means methods. I suggest a method to load the array from the file, and a method to retrieve the smallest number in a row, a method to retrieve the smallest number in a column, etc.

Program output might look like this:

Row 1 : 1.45
Row 2 : 1.21
Row 3 : 1.99
Row 4 : 1.42
Row 5 : 1.72
Row 6 : 2.14
Row 7 : 1.05
Row 8 : 2.46
Row 9 : 1.35
Row 10 : 1.53
Column 1 : 1.99
Column 2 : 1.45
Column 3 : 1.05
Column 4 : 2.19
Column 5 : 2.04
Column 6 : 3.46
Column 7 : 1.66
Column 8 : 1.38
Column 9 : 1.42
Column 10: 1.21
Total : 1.05
