Part A - ArrayList 1. Define a function that takes 2 parameters of type int and returns an ArrayList containing a given number of random integers between 1 and a given upper bound. 2. Write Java code to create an ArrayList containing 20 random numbers between 1 and 100 (inclusive) using the function defined in Task 1 and then print out all the numbers in an ascending order. Part B - HashMap 3.
