You could turn it around:
if (results.length >= 3) {
Deque<String> resultList = new ArrayDeque<>(Arrays.asList(results));
order.setAddress(resultList.removeLast());
order.setPhoneNumber(resultList.removeLast());
order.setConsignee(String.join("", resultList));
}

Java String join() Method
January 8, 2025 - Iterable which can be a list or array of elements, needs to be joined. It always returns a concatenated string of elements joined by the delimiter. import java.util.ArrayList; class Main { public static void main(String[] args) { ArrayList<String> arrayOfStrings = new ArrayList<>(); arrayOfStrings.add("Concatenating"); arrayOfStrings.add("the"); arrayOfStrings.add("array"); arrayOfStrings.add("list"); arrayOfStrings.add("elements"); arrayOfStrings.add("with"); arrayOfStrings.add("space"); arrayOfStrings.add("as"); arrayOfStrings.add("delimiter"); // joining arrayList with space between them as delimiter String joinedStr = String.join(" ", arrayOfStrings); System.out.println(joinedStr); } }

Using Java 8 you can do this in a very clean way:
String.join(delimiter, elements);
This works in three ways:
1) directly specifying the elements
String joined1 = String.join(",", "a", "b", "c");
2) using arrays
String[] array = new String[] { "a", "b", "c" };
String joined2 = String.join(",", array);
3) using iterables
List<String> list = Arrays.asList(array);
String joined3 = String.join(",", list);

Java - Join and Split Arrays and Collections | Baeldung
April 4, 2025 - In this quick tutorial, we’ll learn how to join and to split Arrays and Collections in Java, making good use of the new stream support. Let’s start by joining two Arrays together using Stream.concat: @Test public void whenJoiningTwoArrays_thenJoined() { String[] animals1 = new String[] { "Dog", "Cat" }; String[] animals2 = new String[] { "Bird", "Cow" }; String[] result = Stream.concat( Arrays.stream(animals1), Arrays.stream(animals2)).toArray(String[]::new); assertArrayEquals(result, new String[] { "Dog", "Cat", "Bird", "Cow" }); } Let’s do the same join with two Collections: @Test publ

You may use a StringJoiner for that solution.
List<String> mainList = new ArrayList<>(); //The one to contain all Strings from yourList
List<String> yourList = Arrays.asList("Hey", "how", "are", "you"); //The list of Strings
StringJoiner joiner = new StringJoiner(" "); //Space as delimiter, strings will be separated with spaces
for (String s : yourlist) {
joiner.add(s);
}
mainList.add(joiner.toString()); //Add the new concatenated String to your list, in a single string

Java 8 added a StringJoiner class which does exactly what you want (the following code is in Java 9):
List<String> list = List.of("hey", "how", "are", "you");
StringJoiner joiner = new StringJoiner(" ");
list.forEach(str -> joiner.add(str));
System.out.println(joiner.toString()); // hey how are you
// and if you want the final result to be in a list
// Java 9:
list = List.of(joiner.toString());
// anything before Java 9
list = Arrays.asList(joiner.toString());
Another (simpler) way to do it (since Java 8):
String.join(" ", list)

December 27, 2024 - When the join() method encounters null values in the items array, it treats them as "null" strings in the output, resulting in "null, Toaster, null, Microwave". The String.join() method in Java provides a powerful and easy way to concatenate multiple strings with a specified delimiter.

@Taywin · : I think you meant your loop to be :for (int i = 1; i < array[index]; i++ · and NOTfor (int i = 1; i <= array[index]; i++) · Why inclusive? Pseudo code syntax?

@NP-complete · , the word inclusive in pseudo code means you do not include the value in your range. What I said means [1, array_size). If it is exclusive, it means the value will be included in the range.

February 8, 2026 - System.arraycopy is the most fundamental and high-performance way to join arrays. While the syntax is a bit verbose, it works for both primitive types (int, byte, etc.) and reference types (String, Object). import java.util.Arrays; public class ArrayCopyExample { public static void main(String[] args) { int[] array1 = { 1, 2, 3 }; int[] array2 = { 4, 5, 6 }; // 1. Calculate and allocate the size for the new array int[] result = new int[array1.length + array2.length]; // 2. Copy array1 to the beginning (index 0) of result System.arraycopy(array1, 0, result, 0, array1.length); // 3.
