Scanner characters?

Does Java.util.Scanner have input for characters? (Char) Like nextChar or similar. Not string. I would want to make an Array of characters to be able to index Char arrays like you could index Strings in Python.

From what I've seen how people accept character here I've learned that String input is taken first, then use <String object>.charAt() method passing the desired character index to get the character. Alternatively you can convert a String object into a char array by using <String object>.toCharArray() method which returns a character array containing the String object contents. import java.util.Scanner; public class StringToCharArray { public static void main(String[] args) { Scanner reader = new Scanner(System.in); String s = reader.nextLine(); reader.close(); System.out.println("The string:\n" + s); char[] carr = s.toCharArray(); System.out.println("\nThe character array:"); for(int i = 0; i < carr.length; ++i) System.out.print(carr[i] + " "); } } Hth, cmiiw
