Remove a JSON object from a JSON string in Java

Question

I have following JSON string:

[
{"portNumber":3,"queueId":1,"transmitBytes":0,"transmitPackets":0,"transmitErrors":0},
{"portNumber":2,"queueId":0,"transmitBytes":12940,"transmitPackets":199,"transmitErrors":0},
{"portNumber":2,"queueId":1,"transmitBytes":70,"transmitPackets":1,"transmitErrors":0},
{"portNumber":2,"queueId":2,"transmitBytes":0,"transmitPackets":0,"transmitErrors":0}
]

and I want to remove the whole second JSON object from my string (which has queueId:0). I have tried the .substring class but could not find any useful solutions for this purpose. Any suggestion ?.

Answer 1

If the string is in JSON format, you could just parse the json and store the string as a JSONArray and then remove the value with queueID = 0 from that. String manipulation on Strings in JSON format is not advised and can become complex.
