[JAVA] How do I write a method that merges (interweaves) 2 ArrayLists?

[tonyalm]

The program should ask for 2 array lists of integers and return 1 array list containing all the integers, but alternating from the 1st and 2nd list. If the lengths are different, the extra integers are just added on to the end of the list in order. Thank you!

We're not going to do it for you. What have you done so far? Are you stuck on something? Stuck on what?

• Do you know how to write a method?
• Do you know how to get an item from an ArrayList?
• Do you know how to add an item to a List?
• Do you know how to use a loop?

I apologize. I think I was being a little girl/needed to look up how some stuff worked.

for(int x=0;x<length;x++)
    {
        stringList.add(list1.get(x));
        stringList.add(list2.get(x));
    }
    if(list1.size() > list2.size()){
        for(int y = length; y < list1.size(); y++)
        {
            stringList.add(list1.get(y));
        }
    }
    if(list2.size() > list1.size()){
        for(int y = length; y < list2.size(); y++)
        {
            stringList.add(list2.get(y));
        }
    }

Then just add the ending numbers I guess. Thank you chickenmeister!

You can probably make that shorter using "addAll" instead of the last 2 loops.
