1. Please find the example in java.net.* API Setting a cookie value in a request:

a. Values must be set prior to calling the connect method:

URL myUrl = new URL("http://www.hccp.org/cookieTest.jsp");
URLConnection urlConn = myUrl.openConnection();

b. Create a cookie string:

String myCookie = "userId=igbrown";

c. Add the cookie to a request:
Using the setRequestProperty(String name, String value); method,
we will add a property named "Cookie",
passing the cookie string created in the previous step as the property value.

urlConn.setRequestProperty("Cookie", myCookie);

d. Send the cookie to the server:
To send the cookie, simply call connect() on the URLConnection for which we have added the cookie property:

urlConn.connect()
