Answer 1

This is a complete program you can compile and run it.

import java.util.Scanner;

class Strlen{

    public static void main(String...args){
        Scanner sc = new Scanner(System.in);
        System.out.print("\nEnter Your Name =>" +"  ");
        String ab = sc.nextLine();
        System.out.println("\nName Length is:" +len(ab));
    }

    public static int len(String ab){
        char[] ac = ab.toCharArray();
        int i = 0, k = 0;

        try{
            for(i=0,k=0;ac[i]!='\0';i++)
                k++;
        }
        catch(Exception e){
        }
        return k;
    }

}
