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).

Skip the ArrayList. Just make an array of char the appropriate length and assign the characters in a loop. Also, don't use .length() inside a loop if you can avoid it. If the length isn't changing, get an atomic value before you start the loop and use the atomic in the loop. It's just a good habit to get into. More on reddit.com

Use this:
String str = "testString";
char[] charArray = str.toCharArray();
Character[] charObjectArray = ArrayUtils.toObject(charArray);

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()

r/learnprogramming on Reddit: Java convert String to char array with escaped characters help
February 24, 2019 -
I'm trying to turn a string into a char array by using .toCharArray() and I thought that if I had escaped characters ("\t", or "\n", etc) in the string it would automatically get converted to one char in the char array but instead the slash and the character after it become their own characters.
Example:
StringBuilder sb = new StringBuilder();
sb.append("\t\tStuff");
char[] stuff = sb.toString().toCharArray();
If I do this, the first char in the array is \ instead of \t. Am I doing something wrong? I've tried this in an online compiler to test it out and it works there so I'm not sure what could be going on.
Here is what I'm seeing
