I am looking to extract certain values from a JSON path of arrays and objects and use these values for further processing and am struggling with accessing those elements. Here is the JSON response:

```
[  
 {  
  "od_pair":"7015400:8727100",
  "buckets":[  
     {  
        "bucket":"C00",
        "original":2,
        "available":2
     },
     {  
        "bucket":"A01",
        "original":76,
        "available":0
     },
     {  
        "bucket":"B01",
        "original":672,
        "available":480
     }
    ]
    },
 {  
  "od_pair":"7015400:8814001",
  "buckets":[  
     {  
        "bucket":"C00",
        "original":2,
        "available":2
     },
     {  
        "bucket":"A01",
        "original":40,
        "available":40
     },
     {  
        "bucket":"B01",
        "original":672,
        "available":672
     },
     {  
        "bucket":"B03",
        "original":632,
        "available":632
     },
     {  
        "bucket":"B05",
        "original":558,
        "available":558
     }
    ]
 }
]

```

I tried accessing the root elements with $ but I could not get further with it.

Here is the test method that I have written. I want to extract the value for od\_pair and within each od\_pair, I need to be able to retrieve the bucket codes and their available numbers.

```
public static void updateBuckets(String ServiceName, String DateOfJourney) throws Exception {
    File jsonExample = new File(System.getProperty("user.dir"), "\\LogAvResponse\\LogAvResponse.json");
    JsonPath jsonPath = new JsonPath(jsonExample);

    List<Object> LegList = jsonPath.getList("$");
    // List<HashMap<String, String>> jsonObjectsInArray = jsonPath.getList("$");

    int NoofLegs = LegList.size();
    System.out.println("No of legs :" + NoofLegs);
    for (int j = 0; j <= NoofLegs; j++)
    // for (HashMap<String, String> jsonObject : jsonObjectsInArray) {
    {

        String OD_Pair = jsonPath.param("j", j).getString("[j].od_pair");
        // String OD_Pair = jsonObject.get("od_pair");

        System.out.println("OD Pair: " + OD_Pair);
        List<Object> BucketsList = jsonPath.param("j", j).getList("[j].buckets");

        int NoOfBuckets = BucketsList.size();
        // System.out.println("OD Pair: " + OD_Pair);
        System.out.println("no of Buckets: " + NoOfBuckets);

        for (int i = 0; i < NoOfBuckets; i++) {
            String BucketCode = jsonPath.param("j", j).param("i", i).getString("[j].buckets[i].bucket");
            String Available = jsonPath.param("j", j).param("i", i).getString("[j].buckets[i].available");

            int BucketCodeColumn = XLUtils.getBucketCodeColumn(BucketCode);
            int ServiceRow = XLUtils.getServiceRow(ServiceName, DateOfJourney, OD_Pair);
            System.out.println("Row of " + ServiceName + ":" + DateOfJourney + "is:" + ServiceRow);
            System.out.println("Bucket Code column of " + BucketCode + " is: " + BucketCodeColumn);
            XLUtils.updateAvailability(ServiceRow, BucketCodeColumn, Available);
        }
    }

}

```

}

This is the error I see:

```
Caused by: 
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup 
failed:
Script1.groovy: 1: unexpected token: [ @ line 1, column 27.
restAssuredJsonRootObject.[j].od_pair

```

Can someone help me please?
