Thread: How do I get this to work? Easy question, I'm just hopeless at it!

This is a string reverse so it should just reverse a word you input into the string. My problem is I dont know how to input a word into the string...help please!!!

The code:

public class rev {

public static String rev (String s) {
String to_return = "";
while(true) {
if(s.equals("")) return to_return;

char c = s.charAt(0);
to_return += c;
s=s.substring(1);


}

}

}

I had a look into this and I think your right about the scanner class but it still confuses me in how to get the string to work?

Well I want it to reverse the word "hello" to "olleh". But I don't know how to tell the java string above to do it.

Its not an assignment, its revision for my exam later this month. I've got about 40 different methods to learn and I need to learn how to do one well so I can use that as a template for the rest to learn etc.. So could you tell me how to make it run please? I've wasted enough time trying to get it to run its becoming stressful!
