provide program called FindSmallest to create a 1D array with 10 integer variables. The value of each integer variable in the 1D array is a random number between 1 and 100. After the 1D array is initialised, write a method to find the smallest number among the 10 integers in the 1D array. The output of the program should firstly display all integers in the 1D array, and then indicate the smallest integer among them as well as the index of the smallest integer in the 1D array. 

2. code program called FindBiggest to create an ArrayList with n integer variables. The program will continually ask the user to input the integer number until the user's input is "0" (zero). After the ArrayList is initialised, write a method to find the biggest number among the entered integers. The output of the program should firstly display all integers, and then indicate the biggest integer among them as well as the index of the biggest integer in the ArrayList. 

3. program code called ShoppingList. The program will continuously ask the user to input the name of items on a shopping list (one item each time) until the user's input is "None". The program will store the user's items in an instance of ArrayList. Once the user completes the inputting, the program will output all items on the shopping list (one item each line, and "None" should not be printed).
