More Sam-I-Am

Locked

From now on, green eggs and ham will be overshadowed by lists. Or would the opposite be better? Here's our task: add some of Dr. Suess's famous words to a list: "Sam", "I", "Am". After each word, we'll insert "Ham" into the list. And display the result on the screen. Each list element on a new line.

Is there a better way to do this than manually placing each "Ham" into the list? Could it be written into a for loop for example?

Yes there is:

public class Solution {
    public static void main(String[] args) throws Exception {
        //write your code here
        ArrayList<String> list = new ArrayList<String>();
        list.add("Sam");
        list.add("I");
        list.add("Am");

        for (int x = 0; x < list.size(); x++) {
            if (list.get(x).equals("Ham")) {continue;}
            if (x == list.size()) {break;}
            else {list.add(x+1, "Ham");}
        }

        int size = list.size();
        for (int y = 0; y < size; y++) {
            System.out.println(list.get(y));
        }
    }
}

although the following is acceptable way to do it, it doesn't pass. FYI, ArrayList<String> list = new ArrayList<>(Arrays.asList("Sam", "I", "Am"));

Seeing as the instructions are unclear, you have to enter each word individually and only use one ArrayList for the "Declare a string list variable and immediately initialize it" to work. This exercise is more about showing that you can dynamically insert words between other words in an ArrayList. Don't do what I did and spend 45 minutes overcomplicating it for it to run correctly but still not pass verification.

Verifier does not like this: ArrayList<String> list = new ArrayList<>(Arrays.asList("Sam","I","Am"));

It wants you add one by one... unfortunately.

Someone can display the correct result: all below is wrong... 0 Sam 1 Ham 2 I 1 Ham 4 am 1 Ham _____________________ 1 Ham 4 Am 1 Ham 2 I 1 Ham 0 Sam

This one could do with the example output, as I first created a code which output: SamHam IHam AmHam which was actually more challenging to do than the intended output.

Should the output be: Sam Ham I Ham Am Ham OR SamHam IHam AmHam ?
