A string that contains no characters has length 0.
Let us write a method that computes the length of a string.
The Java class String includes a method length()
so it seems odd to write such a method.
But string length is a really good example of recursion.
Pretend that the people who wrote String forgot to include a length() method,
so now you are stuck with the job.
Recall that a String uses double quotes.
"x" is a String of length one.
A char constant uses single quotes, 'x'.
What is the length of each of the strings in the table?
Say that you know that the length of
uperfragilisticexpialadocious
is 29. What is the length of
Superfragilisticexpialadocious
