Replace Space to Hyphen

Question

I am trying to replace a space character into a hyphen I have in my string.

String replaceText = \"AT AT\";
replaceText.replace(\' \', \'-\');

Answer 1

The replace method returns a String, so you need to re-assign your string variable i.e.

String replaceText = "AT AT";                         
replaceText = replaceText.replace(' ', '-');
