In this tutorial we are going to see how to get the length of any input string without using the length() function in Java.

Here is the code goes:

import java.io.*;
import java.util.Scanner;

public class lengthofstring {
     public static void main(String args[])
   {
       Scanner sc = new Scanner(System.in);
        String mystring;
        mystring = sc.next();
        int count = 0;
        for(char c : mystring.toCharArray())
        {
             count++;
        }
        System.out.println("length is: " + count);
   }
}

I hope this would help you for Interviews!
