Reverse a word with a function

Lugi5000

Hello!

I want to make a program that includes a function. The function should reverse a word. For example if I type in Hello, it should end up with olleH. My question is how the code would look like for this program.

Thank you in advance, Lugi5000

GoToLoop

String txt = "Ipsis Lorem";
String rev = new String(reverse(txt.toCharArray()));

println(txt);
println(rev);

exit();

Thank you for your answer!

GoToLoop

String txt = "Ipsis Lorem";
String rev = new StringBuilder(txt).reverse().toString();

println(txt);
println(rev);

exit();

@Lugi5000 -- Notice that the solution by @GoToLoop treats the string as a list of characters (a character array). You can use reverse() to reverse any array.

@jeremydouglass But what if I reverse the word with a string and the command return?

I don't understand. Is that a question? What if...?

@jeremydouglass Yes this is a question. I am sorry, I am from Austria :)

String txt = "Ipsis Lorem", rev;

  println(txt);

static final String reverseString(final CharSequence str) {
  return new StringBuilder(str).reverse().toString();
}

Oh, I see. "What if" is perfectly good English -- I just wasn't understanding "and the command return." You want to use a function, and then return its value with return, like in GoToLoop's example.
