Convert between String and Char Array in Java
Convert a String to an Array of Characters
The String.toCharArray() method converts a string to a new character array.
1 2 3 4 | String str = "abcde";char[] arr = str.toCharArray();for (char c : arr) System.out.println(c); |
The following code gets an array of Character objects, instead of a character array.
1 2 3 4 | String str = "abcde";Character[] arr = new Characer[str.length()];for (int i = 0; i < str.length(); i++) arr[i] = str.charAt(i); |
Convert an Array of Characters to a String
A string can be directly created from a character array.
1 2 3 | char[] arr = {'a', 'b', 'c', 'd', 'e'};String str = new String(arr);System.out.println(str); |
From an array of Character objects, we can first convert it to a character array.
1 2 3 4 5 | Character[] cs = {'a', 'b', 'c', 'd', 'e'};char arr = new char[cs.length];for (int i = 0; i < cs.length; i++) arr[i] = cs[i];String str = new String(arr); |
