Question

Code in java

Using the template below:

public class Lab03 {
public static void main(String[] args) {
ArrayList<Integer> list1 = new ArrayList<Integer>();
Collections.addAll(list1, 1, 3, 5, 5 );
ArrayList<Integer> list2 = new ArrayList<Integer>();
Collections.addAll(list2, 3, 7, 3, 2, 4 );
ArrayList<Integer> result1= uniqueUnion(list1,list2);
System.out.println(result1);

Integer[] array = new Integer[]{ 29, 28, 27, 16, 15, -14, 3, -2, 2};
ArrayList<Integer> arrayList = new ArrayList<Integer>(Arrays.asList(array));
System.out.printf("The average is: %.2f%n", averagePositive(arrayList));

} // end main

public static ArrayList<Integer> uniqueUnion(ArrayList<Integer> list1, ArrayList<Integer> list2) {
  

return null;

Write a static method named uniqueUnion that takes two ArrayList of integers as arguments and returns a new ArrayList by eliminating the duplicate values in both ArrayLists For example Test Result ArrayList<Integer> listi - new ArrayList<Integer[1, 3, 5, 7, 2, 4] Collections.addAll(listl, 1, 3, 5, 5); ArrayList<Integer list2-new ArrayList<Integer>) Collections.addAll(list2, 3, 7, 3, 2, 4 ); ArrayList<Integery resultl- uniqueUnion(list1,list2) System.out.println(result1); Answer (penalty regime: 0 %) 1 public static ArrayList<Integer uniqueUnion Check

Answer 1

public static ArrayList<Integer> uniqueUnion(ArrayList<Integer> list1, ArrayList<Integer> list2) {
    ArrayList<Integer> result = new ArrayList<Integer>();
    for (int i = 0; i < list1.size(); i++) {
        if (!result.contains(list1.get(i))) {
            result.add(list1.get(i));
        }
    }
    for (int i = 0; i < list2.size(); i++) {
        if (!result.contains(list2.get(i))) {
            result.add(list2.get(i));
        }
    }
    return result;
}
