how to iterate through json objects in java

may help you . You don't have an array - you have properties with names of "000" etc. An array would look like this:
"array": [ {
    "foo": "bar1",
    "baz": "qux1"
  }, {
    "foo": "bar2",
    "baz": "qux2"
  }
]
// Unfortunately keys() just returns a raw Iterator...
Iterator keys = jsonObject.keys();
while (keys.hasNext()) {
    Object key = keys.next();
    JSONObject value = jsonObject.getJSONObject((String) key);
    String component = value.getString("component");
    System.out.println(component);
}
@SuppressWarnings("unchecked")
Iterator<String> keys = (Iterator<String>) jsonObject.keys();
while (keys.hasNext()) {
    String key = keys.next();
    JSONObject value = jsonObject.getJSONObject(key);
    String component = value.getString("component");
    System.out.println(component);
}

java android - iterate JSON objects in array


Tag : java , By : Bart van Bragt

this one helps. This is a classic problem of instance shadowing. You declare a new variable in your method, in the try block, with the same name as a class variable. So, the class variable is shadowed and thus, never initialized. When you later return it from the method, its null.
public class EnvConfig {

    private String rawJSONString;
    private JSONObject jsonObjRecv; // <-- you declare a class variable here

    // ...

    try {
        JSONObject jsonObjRecv = new JSONObject(rawJSONString); // <-- shadowed here!

Need to iterate through stored json objects in local storage array of json data

With these it helps If you have a string representation of a JSON object, one way to turn it into a javascript object to iterate through is:
eval(offlinExtractData)[3]
JSON.parse(offlinExtractData)[3]

How to iterate over json Array having multiple json objects with different header

To fix this issue Based on the classes and methods you're using, I'm assuming you use org.primefaces.json classes. But even if you're using a different API, the logic will be basically the same.
First of all, look at your JSON structure:
[
  {
    "mutualFund": {
      "fundCode": "XYZ",
      "fundName": "Funds-GlobalIncomeFund(G)-SGD","isin":"LU0882574725","sedol":"1234"
     }
  },
  {
    "brokers": {
      "fundID": "abcd",
      "fundName": "Funds-FocusFundA-USD","isin":"LU0197229882","sedol":"6543"
    }
  }
]
for (int i = 0; i < jsonArray.length(); i++) {
    // get object i
    JSONObject jsonObject = jsonArray.getJSONObject(i);
    // check if object has mutualFund key
    if (jsonObject.has("mutualFund")) {
        // get mutualFund object and do something with it
        JSONObject mutualFund = jsonObject.getJSONObject("mutualFund");
        // do something with mutualFund object (you can get values for fundCode and fundName keys, etc)
    }
}

Java - How to iterate through an objects arraylist and adding elements that meet a certain condition to another objects

like below fixes the issue A couple problems:
I think you're getting a new iterator on each loop. You call next() twice when you intend to get the same object, getting two subsequent objects.
for (User u : myUserGroup.userList) {
  if (u.getUserType().equals("admin")) {
    administrators.userList.add(u);
  }
}
