length of the string

[s john smith]

how to find the nuber of characters in the string without using length() or any standard library function?

[Rod Singh]

public static  int getStringLength(String str) {		
        return str.toCharArray().length;
}

That works if you don't count toCharArray as a "standard library function". Which is fine with me, it's up to the question-setter to define what a "library function" is and how you tell whether it's "standard" or not.

You've already been told it's not possible. If you don't like the answers you got, please discuss them in that thread, rather than starting a new one with the same question.

How is String.toCharArray() not a "standard library function"?
