从 Map 中查找部分键及其值<String, String>在 Java 中

Question

I've this map key value pair as :

{$skip=28, $landingPageURL=https://www.example.com, $gtmCount=gtmMPCL, $url=mpclProd, $trackingJson=mpclNonAmpTracking.json, $portalCD=portal_CD_MPCL}

and I need to findout the key as $landingPageURL?utm_medium=lp_automation from the above map. So, my final output should be for **$landingPageURL?utm_medium=lp_automation** as https://www.example.com?utm_medium=lp_automation (because $landingPageURL is replaced with above map).

How do I achieve this with condition something like

if(map.partialcontainskey(keyname) so, as example, it should conditionally check if $landingPageURL.partialcontainskey($landingPageURL?utm_medium=lp_automation).

how do i achieve this. Your help is appreciated.

Answer 1

If your input is following

String input = landingPageURL?utm_medium=lp_automation;

You can split the input string and get the required key as follows:

String[] urlComponents = input.split("?");
String key = urlComponents[0];
String queryString = urlComponents[1];

And finally you can generate your output as follows:

String output = map.get(key)+"?"+queryString;
