We would like to know how to get String length without using length() method.
//from ww w. j av a 2 s.c o m public class Main { public static void main(String... args) { System.out.println("\nName Length is:" + len("java2s.com")); } public static int len(String ab) { char[] ac = ab.toCharArray(); int i = 0, k = 0; for (i = 0, k = 0; ac[i] != '\0'; i++){ k++; } return k; } }
