.copyValueOf()

Returns a string with characters copied from an array.

string.copyValueOf(char[] data, int offset, int count)

• data (required): An array of characters to be copied from.
• offset (optional): The index of the first character to be copied.
• count (optional): The number of characters to be copied.

Copy all characters from the charactersArray array to the copiedCharacters string:

class CopyAllCharacters {
  public static void main(String[] args) {
    String copiedCharacters = "This string will be replaced with copied characters.";
    char[] charactersArray = {'a','b','c','d','e'};

    System.out.println(copiedCharacters.copyValueOf(charactersArray));
    // Output: abcde
  }
}

Copy two characters from the array, starting at index 4:

class SpecificCharactersToCopy {
  public static void main(String[] args) {
    String copiedCharacters = "This string will be replaced with copied characters.";
    char[] charactersArray = {'a','b','c','d','e','f','g','h','i'};

    System.out.println(copiedCharacters.copyValueOf(charactersArray, 4, 2));
    // Output: ef
  }
}
