问题描述
好的，所以我对Java编程很陌生，到目前为止我已经能够匆匆忙忙了，但是我完全坚持这个任务。这是本周到期的作业 -
？修改库存程序，以便应用程序可以处理多个项目。使用数组存储项目。输出应一次显示一个产品的信息，包括产品编号，产品名称，库存单位数量，每个单位的价格以及该产品的库存价值。此外，输出应显示整个库存的价值。
？创建一种方法来计算整个库存的价值。
？创建另一种方法，按产品名称对数组项进行排序。不要使用array.sort。
编译并运行Java程序。

OK, so I''m very new to Java programming and I''ve been able to squeek by so far, but I''m completely stuck on this assignment. Here is the assignment that is due this week -
? 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. DON''T use array.sort.
Compile and run the Java program.
And here is my code from last week -
