How can I write this simple Java 8 line of code into Java 7

Question

I'm trying to implement a CSRF token, but all the info is programmed with Java 8+ version, so what I need is some help rewriting this line in Java 6/7:

tokenCookie = Arrays.stream(httpReq.getCookies()).filter(c -> c.getName().equals(csrfCookieExpectedName)).findFirst().orElse(null);

Actually from that line I'm only getting the error in:

c -> c.getName().equals(csrfCookieExpectedName)

In addition to @GIO's answer, you could try for-each loop like this:

public Cookie getExpectedCookieName(Cookie[] cookies) {
    for (Cookie c : cookies) {
        if (c.getName().equals(csrfCookiesExpectedName)) {
            return c;
        }
    }
    return null;
}

and call it like this : tokenCookie = getExpectedCookieName(httpReq.getCookies());
