How to access JSON array in Java?

Question

I need to get elementId from my JSON file which is shown below:

{
    "intents": [{
        "type": "PathIntent",
        "id": "0x0",
        "appId": "org.onosproject.cli",
        "resources": ["DefaultLink{src=ConnectPoint{elementId=00:00:00:00:00:01/-1, portNumber=0}, dst=ConnectPoint{elementId=of:0000000000000003, portNumber=1}, type=EDGE, state=ACTIVE, durable=false}", "DefaultLink{src=ConnectPoint{elementId=of:0000000000000003, portNumber=3}, dst=ConnectPoint{elementId=of:0000000000000002, portNumber=1}, type=DIRECT, state=ACTIVE, durable=false}", "DefaultLink{src=ConnectPoint{elementId=of:0000000000000002, portNumber=2}, dst=ConnectPoint{elementId=of:0000000000000004, portNumber=3}, type=DIRECT, state=ACTIVE, durable=false}", "DefaultLink{src=ConnectPoint{elementId=of:0000000000000004, portNumber=2}, dst=ConnectPoint{elementId=00:00:00:00:00:04/-1, portNumber=0}, type=EDGE, state=ACTIVE, durable=false}"],
        "state": "INSTALLED"
    }]
}

Answer 1

To get an JSON-Array is very easy:

JSONObject obj = new JSONObject("...");
JSONArray arr = obj.getJSONArray("resources");

You will get an array of this elements

"DefaultLink{src=ConnectPoint{elementId=00:00:00:00:00:01/-1, portNumber=0}, dst=ConnectPoint{elementId=of:0000000000000003, portNumber=1}, type=EDGE, state=ACTIVE, durable=false}" 

Unfortunately you need to parse the String i guess.
