How do you add a value to a 2-d array by row number and column number?
Let's say I have a 2-d array of doubles of 3 rows and 5 columns named sales
double [][] sales = new double [3][5];
How do i add a value to a specific row and column, or cell? I am trying to write a program that asks user for the row number, the column number, the value to input and add that value to the cell/row and column?

You can change the contents of an array by assigning it a value using indexes:theArray{theRow][theCol] = theValue; // assign value to slot
Remember indexes start at 0 and go to the array length-1
If you don't understand my answer, don't ignore it, ask a question.
