I’m getting a compilation error when I use this regular expression inside the String class’s matches() method. Anyone know what I’m doing wrong here? Thanks

String email = "this@that.com";
System.out.println(email.matches("^(.+@.+\.\\w{2,4})$"));

    escape period . with two backslashes \\. valid escape sequences supported in java are \b \t \n \f \r \" \' \\

    System.out.println(email.matches("^(.+@.+\\.\\w{2,4})$"));

    OR:

    Enclose it within \\Q and \\E
