iamwsumit · May 14, 2021, 9:35am

Remove the imported package that i have said and then again build it

Nami_Chand · May 14, 2021, 9:44am

Woo hoo! Its success. Build successful.

Nami_Chand · May 14, 2021, 9:46am

I am trying this extension.

How we set permanent key in this code.

iamwsumit · May 14, 2021, 9:47am

I didn’t understand you
Do you want to get the value of a particular key??

Nami_Chand · May 14, 2021, 9:51am

Sorry i want set permanent object in this code.

iamwsumit · May 14, 2021, 9:52am

Hence you don’t need to take the object parameter from the user and replace the object string with your JSON object

Nami_Chand · May 14, 2021, 9:53am

how please write the code.

iamwsumit · May 14, 2021, 9:55am

Just remove the object param from your function like this

@SimpleFunction
public Object GetValue(String key){
     String object="your json here";
    JSONObject object=new JSONObject(object);
    return object.getString(key);
}

If you also want to use permanent key then do the same by removing the key param and after specify it in your function same like object

Nami_Chand · May 14, 2021, 9:59am

Where do you get the sample code?
tell me for learn.

iamwsumit · May 14, 2021, 10:00am

From my mind
It’s my own code if you want to learn then just google about json in java and you will get all the info about JSON

Or more here

https://www.tutorialspoint.com/json/json_java_example.htm

Nami_Chand · May 14, 2021, 10:06am

But these code are different from your codes.
Tell me how to convert.

Bharat mata ki jai.

Pradevel · May 15, 2021, 7:11am

If you ask me then thats not how coding in any language works
you forst need to understand the stuff that you are doing in this case Json
So you first have to understands for Json objects work and some basic java stuff

If you just copy/paste stuff then there is no type of learning in it.
And programming isn’t just copy pasting!

Hope this helps
I am not trying to be rude

Nami_Chand · May 15, 2021, 7:14am

But there are no more tutorial on youtube for learn.
