Regular expression not working using java

Question

I need to create regex using java to capture substrings that satisfies following conditions:

1. Either starts with "34" or "37"
2. are 15 digits long (ex. "379081815400122")

My code is:

import java.util.Date;
import java.util.regex.Pattern;

public class HelloWorld {
    public static void main(String[] args) {
        String text = "\\\"370000000000000\\\"";
        String pattern = "3[47][0-9]{13}";
        boolean matches = Pattern.matches(pattern, text);
        System.out.println("matches = " + matches);
    }
}

but it not working and prints false instead of true. I don't understand what modification it requires to print true as my text contain "370000000000000" which is 15 digit and starts with 37.
