Posted in : Java Beginners


Using a selection sort, for each entry in the array, display the original index of the first dimension, the second dimension's value, and the first dimension's value on a single line separated by : (colon) sorted by the first dimension.

I got the two dimensional array figure out just dont know how to incorporate the above question.

Thanks in advance!
