you can use an Iterator, e.g.

import java.io.*;
import java.util.*;
 
class ArrayListString 
{
public static void main(String s[])
 {
   ArrayList <String>list = new ArrayList <String>(100);    // can store any Nunber
   list.add("Hello");
   list.add("world");
   Iterator iter = list.iterator();
    while (iter.hasNext()) {
      System.out.println("string " + iter.next());
      }
  }
}

when run give
string Hello
string world

Alternatively you could also read the strings out of the list using the get method of arraylist.
