Question
java
Create a static method that:
- is called appendPosSum
- returns an ArrayList of Integers
- takes one parameter: an ArrayList of Integers
This method should:
- Create a new ArrayList of Integers
- Add only the positive Integers to the new ArrayList
- Sum the positive Integers in the new ArrayList and add the Sum as the last element
For example, if the incoming ArrayList contains the Integers (4,-6,3,-8,0,4,3), the ArrayList that gets returned should be (4,3,4,3,14), with 14 being the sum of (4,3,4,3). The original ArrayList should remain unchanged.
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int size = in.nextInt();
ArrayList<Integer> list = new ArrayList<>();
for(int i=0; i < size; i++) {
list.add(in.nextInt());
}
System.out.println(appendPosSum(list));
}
}
