Hello,
I am having trouble sorting my array. I have gotten it to read out just the names in ABC order, but I need it to display all of the attributes. I have read several sites trying to figure out how to do it and I keep getting errors. Here is my code, can anyone help me atleast understand if I am putting the code in the right spot. Most websites show sort() in its own file not being added to one. Thanks.
package inventory;
import java.text.DecimalFormat;
