Hello All! I am really new here (this is my first post), and am only in my 3rd week of a
Java course. I took C++ and have a little bit of other languages under my belt, so I am catching on to the main topics quite well, but I have one burning question.
I am trying to get a 2D array to print out correctly. It is for an exercise for class, and I have gotten all of it but this part. The instructor just wants different sales numbers to show up for 5 different states for 3 different items. Not a big deal. I have the data printing out, but it is all on one line. Here is the code in the loops in the print method (I would copy all of it but am working on a different machine; I got a virus on my main machine and can't get on the Internet yet):
int rowSize = productSales.length;
int colSize = productSales[0].length;
for (int row = 0; row < rowSize; row = row + 1) {
salesReport = salesReport + salesRegion[row];
for (int col = 0; col < colSize; col = col + 1) {
salesReport = salesReport + "\t" + "\t" + "\t"+moneyFormat.format(productSales[row][col]);
} // end col loop
} // end row loop
There are 4 column titles; the state (hard-coded values in a separate method), then the columns for the 3 product's sales (hard-coded as well). There are 5 states to account for. However, it prints out like this:
Illinois $10 $10 $20Indiana $30 $40 $50Michigan $10 $20 $30Ohio $60 $80 $50Wisconsin $90 $80 $50
It is supposed to look like this:
Illinois $10 $10 $20
Indiana $30 $40 $50
Michigan $10 $20 $30
Ohio $60 $80 $50
Wisconsin $90 $80 $50
With column titles and all of that other stuff.
The moneyFormat is just a defined format in the same method but outside the loop. The value of the array is returned to the main method and printed to the screen from there. I have tried using a System.out.println statement of just a space outside of the col loop but still inside the row loop but to no avail. This is just an exercise for class so it doesn't have to be handed in, but our assignment is based on it. I have gotten this far, but seem to be stuck at what may be one of the easiest things to do! Any help would be GREATLY appreciated! Thanks so much!
