this is advance java. please when writing the code separate the class from the main.

CT 2613 Advanced Java Assignment: Arraylist and Two-Dimensional Array Part A: ArrayList Assignment Write a program that allows you to enter a series of numbers (ints). Each time a new number is entered, add it to an ArrayList. Let the user stop the data entry by entering a -1 When data entry is done, display the contents of the list using your own for loop. (or for-each) Also, calculate and display the sum and the average of the elements in the list Remember that you can't store int values directly in an ArrayList -you have to use Integer (wrapper class) to declare your ArrayList. This won't work: ArrayList numbers.. Instead, you would either declare them like this: ArrayList numbers Or as an Arraylist of Strings and convert them to ints as needed. 1 don't recommend this.) Part B: two-dimensional array assignment. Write a program that will ask the user: For the number of rows in the array For the number of columns in the array Then the program should: . Declare and allocate an array of ints of that size . Fill the array (iterate thru every value with a nested loop) with random numbers between 1 and 9 . Display the two-d array appropriately
