Read JSON property in Java

Question

I am getting below output when I am calling postAPI from java. I want to store access_token in a variable but I am not able to do it. in javascript I can do it easily but in Java it is becoming difficult for me. Can anybody help me on the same.

What do you mean with difficult to store the access_token in a variable? From what you wrote I would declare a String variable to hold the access_token. But I assume that there is more behind what you asked. — wizardofOz, Jun 28 '20 at 16:38
"I am not able to do it" is not a problem description: what have you _actually_ tried that doesn't seem to work? Because there are several libraries for parsing JSON in Java, and they're all extremely easily found with a single google search. — Mike 'Pomax' Kamermans, Jun 28 '20 at 16:41

@Mike'Pomax'Kamermans Thank you Mike. I did try jackson but I was getting error. probably I was not including maven dependency. By the way why did you downvote the question? — Shruti sharma, Jun 28 '20 at 16:45
@mohammedkhan Thank you Mohammed Khan. it helped to complete the requirement — Shruti sharma, Jun 28 '20 at 16:46
