HttpCookie setVersion(int) in Java

setVersion(int): This method is available in the java.net.HttpCookie class of Java.

Syntax:

void java.net.HttpCookie.setVersion(int v)

This method takes one argument. This method sets the version of the cookie protocol this cookie complies with.

Version 0 complies with the original Netscape cookie specification. Version 1 complies with RFC 2965/2109.

Parameters: One parameter is required for this method.

v: 0 if the cookie should comply with the original Netscape specification; 1 if the cookie should comply with RFC 2965/2109.

Returns: NA

Throws:

1. IllegalArgumentException - if v is neither 0 nor 1.

Approach 1: When no exception

Java

package com.HttpCookie;

import java.net.HttpCookie;

public class HttpCookiesetVersion {
    public static void main(String[] args) {

        HttpCookie httpCookie = new HttpCookie("name", "value");

        int v = 1;
        httpCookie.setVersion(v);
        System.out.println("Successfully setVersion");
    }
}

Output:

Successfully setVersion

Approach 2: IllegalArgumentException

Java

package com.HttpCookie;

import java.net.HttpCookie;

public class HttpCookiesetVersion {
    public static void main(String[] args) {

        HttpCookie httpCookie = new HttpCookie("name", "value");

        int v = 10;
        httpCookie.setVersion(v);
        System.out.println("Successfully setVersion");
    }
}

Output:

Exception in thread "main" java.lang.IllegalArgumentException: cookie version should be 0 or 1
	at java.base/java.net.HttpCookie.setVersion(HttpCookie.java:559)
	at com.HttpCookie.HttpCookiesetVersion.main(HttpCookiesetVersion.java:11)
