Итерация через Java Arraylist Java

// will iterate through each index of the array list
// using the size of the array list as the max.
// (the last index is the size of the array list - 1)

for (int i = 0; i < myArrayList.size(); i++) {
  
  System.out.println(myArrayList.get(i));
  // will print each index as it loops

    String code = "JTI-1 ";
    for (int i = 0; i < contain.size(); i++) {
        if (contain.get(i).contains(code.trim())) {<---Use trim it is possible that code may have extra space
            System.out.println(contain.get(i));
