    replace text in a string

    All I want to do is search for "\\n" and replace it with "\n". However there appears to be no simple way to do this - am I missing something or am I going to have to write some kind of complex if then statement etc. to do this.

    Currently I was trying to use the java.lang.replace method, but it appears you can only search/change one character at a time w/ this, as I'm getting an error when I run:

    String Ntext = "Here is a newline \\n newline";
    String Rtext = Ntext.replace('\\n','\n');

    The following code shows how to replace \\n with \n.

    String text = "Hello,\\nHow are you today?";
    String newText = text.replaceAll("\\\\n","\n");
    System.out.println (newText);
    The reason for the \\\\n is because the String.replaceAll method creates a regular expression and the \ has special meaning there. So you have to escape once for the regular expressions and once again for Java. So instead of writing \\n you must write \\\\n. Enjoy!

    For more help,
