Use set method to change the value in an array list

      

import java.util.ArrayList;

public class MainClass {
  public static void main(String[] a) {
    ArrayList<String> nums = new ArrayList<String>();
    nums.clear();
    nums.add("One");
    nums.add("Two");
    nums.add("Three");

    System.out.println(nums);
    nums.set(0, "Uno");
    nums.set(1, "Dos");
    nums.set(2, "Tres");
    System.out.println(nums);
  }
}
