  • Define the shouldAccept method of CookiePolicy and program according to our need.

Examples

 1. Java program to set cookieManager cookie policy to accept all the cookies –

Java




import java.net.*;
class GFG {
    public static void main(String[] args)
    {
        // create instance of cookieManager
        CookieManager cookieManager = new CookieManager();
        // set cookieManager cookie policy using
        // setCookiePolicy method
        cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);
        System.out.println("Cookie Policy for cookieManager is set to : CookiePolicy.ACCEPT_ALL");
    }
}


Output

Cookie Policy for cookieManager is set to : CookiePolicy.ACCEPT_ALL

2. Java program to set cookieManager cookie policy to accept no cookies –

Java




import java.net.*;
class GFG {
    public static void main(String[] args)
    {
        // create instance of cookieManager
        CookieManager cookieManager = new CookieManager();
        // set cookieManager cookie policy using
        // setCookiePolicy method
        cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_NONE);
        System.out.println("Cookie Policy for cookieManager is set to : CookiePolicy.ACCEPT_NONE");
    }
}


Output

Cookie Policy for cookieManager is set to : CookiePolicy.ACCEPT_NONE

3. Java program to set cookieManager cookie policy to accept cookies from the original server only – 

Java




import java.net.*;
class GFG {
    public static void main(String[] args)
    {
        // create instance of cookieManager
        CookieManager cookieManager = new CookieManager();
        // set cookieManager cookie policy using
        // setCookiePolicy method
        cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ORIGINAL_SERVER);
        System.out.println("Cookie Policy for cookieManager is set to : CookiePolicy.ACCEPT_ORIGINAL_SERVER");
