New To Java - null
This is what my professor wants us to do
Modify the Inventory Program so the application can handle multiple items. Use an array to store the items. The output should display the information one product at a time, including the item number, the name of the product, the number of units in stock, the price of each unit, and the value of the inventory of that product. In addition, the output should display the value of the entire inventory.
?Create a method to calculate the value of the entire inventory.
?Create another method to sort the array items by the name of the product.
The error I keep getting when I try to compile it is :
C:\IT215\Inventory2.java:98: illegal start of expression
private static void printArray(DVD[] myDVD) {
^
C:\IT215\Inventory2.java:179: reached end of file while parsing

Here is the code
