Given the following code: 1. Write a foreach using lambda expression to print all the elements of the ArrayList. (2 pts) 2. Write a lambda expression that returns the average of all the elements' lengths in the ArrayList. If you have this functional interface: interface Calc{ double calculate (ArrayList<String> items); } Sample input and output: Input: ArrayList<String> items = new ArrayList<String>(); items.add("Bob"); items.add("Samantha"); items.add("Emily"); items.add("Jack"); items.add("Lina"); ArrayList<String> items = new ArrayList<>(); Output: 4.8 Given the following code: 1.
