Array list

Question

How to write code for Negative numbers using arraylist in java

Answer 1

import java.util.ArrayList;
Line 11: numbers.add(i);

I am not sure what you mean with negative numbers.

E.g.
ArrayList<Integer> negative = negativeNumbers(1, 10);
Do you want to add -1, -2, ... -9?

Answer 2

do changes from Denise and

System.out.println(negativeNumbers(-10,0));
...
for(int i = firstValue; i <= endValue; i++){ //<=

ArrayList<Integer> als = new ArrayList<>(List.of(1,2,3,4,5) );
als.add(6);
System.out.println(als);
