como eliminar ceros en un inicio de un String, TrimStart('0')

hi, I'm trying to do the following,

Streng writ = ("0016668972"); This variable stores the personal identification numbers, I need to remove those zeros and stay so that the result

Writ String = ("16668972");

thank you

I need to remove those zeros

So, what's the problem? charAt( 0 ) will tell you what the first character is. If it's a '0', remove it, and start over.
