<h3 id="String_literals">String literals</h3>

<p>
A string literal represents a <a href="#Constants">string constant</a>
obtained from concatenating a sequence of characters. There are two forms:
raw string literals and interpreted string literals.
</p>

<p>
Raw string literals are character sequences between back quotes, as in

    if (addr == null) {
      throw formatIllegalArgumentException("'%s' is not an IP string literal.", ipString);
    }

    return bytesToInetAddress(addr, scope.scope);
  }
