How do I into java

Any Javafags here?

So I'm trying too write a program that will print the letters of a string backwards on each line, but I can only get it too print the last letter of the string infinitely. Can anyone show me how I would get the result I want?

This is what I wrote so far:

String word = "anything";
        int length = word.length();
        char letter = word.charAt(length-1);
        while(length > 0)
        System.out.println(letter);

I'm trying to teach my self java, so any help is much appreciated.

It might as well be, I learned Alice in highschool but I didn't get a whole lot out of that besides the absolute basics of programming.
