No, that solution is absolutely correct and very minimal.
Note however, that this is a very unusual situation: Because String is handled specially in Java, even "foo" is actually a String. So the need for splitting a String into individual chars and join them back is not required in normal code.
Compare this to C/C++ where "foo" you have a bundle of chars terminated by a zero byte on one side and string on the other side and many conversions between them due do legacy methods.

String text = String.copyValueOf(data);
or
String text = String.valueOf(data);
is arguably better (encapsulates the new String call).

Convert Character Array to String in Java | Baeldung
January 8, 2024 - @Test public void whenStringValueOf_thenOK() { final char[] charArray = { 'b', 'a', 'e', 'l', 'd', 'u', 'n', 'g' }; String string = String.valueOf(charArray); assertThat(string, is("baeldung")); } String#copyValueOf is another method that’s semantically equivalent to the valueOf() method but was of any significance only in a first few Java releases. As of today, the copyValueOf() method is redundant and we don’t recommend using it. What if we want to form a String from an array of char arrays?
Converting String to "Character" array in Java - Stack Overflow

Moving characters from an array to a string
You just need to pass the char array into the constructor of a new String. char[] textArray = { 'a', 'b', 'c'}; String text = new String(textArray); Source: Oracle Documentation of the String Class Actually, it looks like your loop code for joining the String might be wrong: You quoted String y = "" + charArr[x]; inside your for loop. If you have it like that it will effectively overwrite the previous string. You need to do it like: String y = ""; for(int x = 0; x < charArr.length; x++) { y = y + charArr[x]; } But this is not the proper way to join Strings in loops in Java. Strings are immutable objects. Joining Strings should be done with a StringBuilder : StringBuilder y = ""; for(int x = 0; x < charArr.length; x++) { y.append(charArr[x]); } System.out.println(y.toString()); More on reddit.com

One liner with java-8:
String str = "testString";
//[t, e, s, t, S, t, r, i, n, g]
Character[] charObjectArray =
str.chars().mapToObj(c -> (char)c).toArray(Character[]::new);
What it does is:
- get an
IntStreamof the characters (you may want to also look atcodePoints()) - map each 'character' value to
Character(you need to cast to actually say that its really achar, and then Java will box it automatically toCharacter) - get the resulting array by calling
toArray()
