The function then uses that list, loops through it and multiplies each individual value by 2 and returns the modified list. The first red square represents the test case for the function, while the second red square in the image represents the output.
public static ArrayList<Integer> doubleIt(ArrayList<Integer> mylist) {
for (int x = 0; x<mylist.size(); x++) {
mylist.set(x, mylist.get(x)*2);
}
return mylist;
}
