Print array without brackets and commas

Question

I\'m porting a Hangman game to Android and have met a few problems. The original Java program used the console, so now I have to somehow beautify the output so that it fits

Answer 1

Just initialize a String object with your array

String s=new String(array);

Answer 2

With Java 8 or newer, you can use String.join, which provides the same functionality:

Returns a new String composed of copies of the CharSequence elements joined together with a copy of the specified delimiter

String[] array = new String[] { "a", "n", "d", "r", "o", "i", "d" };
String joined = String.join("", array); //returns "android"

With an array of a different type, one should convert it to a String array or to a char sequence Iterable:

int[] numbers = { 1, 2, 3, 4, 5, 6, 7 };

//both of the following return "1234567"
String joinedNumbers = String.join("",
        Arrays.stream(numbers).mapToObj(String::valueOf).toArray(n -> new String[n]));
String joinedNumbers2 = String.join("",
        Arrays.stream(numbers).mapToObj(String::valueOf).collect(Collectors.toList()));

The first argument to String.join is the delimiter, and can be changed accordingly.

Answer 3

first

StringUtils.join(array, "");

second

Arrays.asList(arr).toString().substring(1).replaceFirst("]", "").replace(", ", "")

EDIT

probably the best one: Arrays.toString(arr)

Answer 4

I used join() function like:

i=new Array("Hi", "Hello", "Cheers", "Greetings");
i=i.join("");

Which Prints:
HiHelloCheersGreetings
