Array- variable cannot be resolved

Array- variable cannot be resolved

The following is code I've written to try to accomplish the following tasks:
have the user enter up to 25 flowers
allow the user to remove one of the flowers
sort the flowers alphabetically
search for a specific flower
display all of the flowers with a value of how many of each type of
flowers are in the array
exit the program
There have been several errors. I looked up how to remove an element from
an array, and it involves the second import as well as the removeItem.
However, eclipse does not recognize the import
(org.apache.commons.lang.ArrayUtils); is there a better way? Or did I type
if wrong. Next it is having problems connecting case 2 through case 5 to
the methods I have created, and I'm not sure why. The most prevalent error
I'm seeing is that n cannot be resolved. I have tried many different ways
of defining n or showing that it represents the index, but nothing I'm
doing is solving the issue. This error occurs at the lines: the first
three lines after the bracket enclosing the addFlower method, under the
removeFlower method at 'if (n <= 0)' and 'if removedItem != flowerPack[n]'
as well as input cannot be resolved at the line above that 'String
removedItem = input.nextLine();', and the ArrayUtils cannot be resolved at
the second else statement under removeFlower,input cannot be resolved when
I try to define what the user inputs under searchFlower at 'String
searchWord = input.nextLine();', n cannot be resolved under
countFlowerTypes 'counts [flowerPack[n]]++;', and there are several errors
on the line 'public static int[] countFlowerTypes(String[] flowerPack){'
including they want ( and ) to be ;, they say it can only be final, and
they call it a duplicate local variable. I know I have many problems, but
I've been trying to look stuff up the last couple of hours and everything
I try just makes it worse. If anyone has any pointers on how to change
these errors that would be extremely helpful. Thanks!
