Question

public static void main(String[] args){
    List<Integer> two = new ArrayList<Integer>;
    two.add("Kyle");
    two.add("Randy");
    two.add("Shaun");

The goal of this program is to make two of all of the strings so it will print out like this
but I am not sure of how I would do this.

Try this

List<String> strings = new ArrayList<String>();
List<String> strings2 = new ArrayList<String>();
for (String s : strings) {
  strings2.add(s);
  strings2.add(s);
}

for(String s : strings2){
    System.out.print(s);
}
