Java JSONArray Iteration Methods

There are several methods that can be used to iterate over a JSONArray in Java.

1. Iterate through the elements in a JSONArray using a for loop.

JSONArray jsonArray = new JSONArray("[{\"name\":\"John\",\"age\":30},{\"name\":\"Jane\",\"age\":25}]");
for (int i = 0; i < jsonArray.length(); i++) {
    JSONObject jsonObj = jsonArray.getJSONObject(i);
    String name = jsonObj.getString("name");
    int age = jsonObj.getInt("age");
    System.out.println("Name: " + name + ", Age: " + age);
}

1. Iterate through the elements in a JSONArray using an iterator.

JSONArray jsonArray = new JSONArray("[{\"name\":\"John\",\"age\":30},{\"name\":\"Jane\",\"age\":25}]");
Iterator<Object> iterator = jsonArray.iterator();
while (iterator.hasNext()) {
    JSONObject jsonObj = (JSONObject) iterator.next();
    String name = jsonObj.getString("name");
    int age = jsonObj.getInt("age");
    System.out.println("Name: " + name + ", Age: " + age);
}

1. Iterate through the elements in a JSONArray using Lambda expressions.

JSONArray jsonArray = new JSONArray("[{\"name\":\"John\",\"age\":30},{\"name\":\"Jane\",\"age\":25}]");
jsonArray.forEach(item -> {
    JSONObject jsonObj = (JSONObject) item;
    String name = jsonObj.getString("name");
    int age = jsonObj.getInt("age");
    System.out.println("Name: " + name + ", Age: " + age);
});

There are three common ways to traverse a JSONArray, and you can choose the appropriate method based on your specific needs when traversing elements in a JSONArray in practical applications.
