Help With My Java Project?

Write a console program that repeatedly prompts the user to enter data until they type done (any case, Upper, Lower, or Mixed). As they enter the data, assign it to a two-dimension array where the first dimension contains exactly what they type and the second dimension contains the first non-whitespace character of what they type, in lowercase. If they enter a blank line, it is acceptable to skip that line. When they type done, do these steps: display: As Entered for each entry in the array, display the index of the first dimension, the second dimension's value, and the first dimension's value on a single line separated by : (colon). display: Bubble Sorted using a bubble 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 second dimension. display: Selection Sorted 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. Grading Notes:

Example:

User types: apple Apple Zone apple done

You display: As entered 0:a:apple 1:a:Apple 2:z:Zone 3:a:apple Bubble Sorted 0:a:apple 1:a:Apple 3:a:apple 2:z:Zone Selection Sorted 1:a:Apple 0:a:apple 3:a:apple 2:z:Zone

Here is what i got and i cant seem to put it all together to make it work. please help
