Java strings

[fungi]

I have a question:
for (int i = text.length()-1; i>=0; i--)
{
//some code
}

What does -1 mean?
I know what these--> i>=0; i-- mean but I do not understand what -1 means?

Thanks

When you're counting the character positions in a string, you start counting at zero. That means that the index of the last character is 1 less than the length of the string. That's why it was necessary to subtract 1 from the length to get the correct starting point.
