Java intergers are appearing as string in Json

If integers are appearing as strings in a JSON object, it is likely because they are being serialized as strings when the object is created. This can happen if the integers are being converted to strings before being added to the object, or if the object is being created using string keys rather than integer keys.

Here is an example of how this could happen:

Map<String, String> map = new HashMap<>();
map.put("key", "123"); // adding the integer 123 as a string

String json = new Gson().toJson(map);

// Output: {"key": "123"}

In this example, the integer 123 is being added to the Map as a string, so it is serialized as a string in the JSON object.

To fix this issue, you can ensure that the integers are not being converted to strings before being added to the object. You can also use integer keys in the object instead of string keys to prevent the values from being serialized as strings.

Here is an example of how to do this:

Map<String, Integer> map = new HashMap<>();
map.put("key", 123); // adding the integer 123 as an integer

String json = new Gson().toJson(map);

// Output: {"key": 123}

In this example, the integer 123 is added to the Map as an integer, so it is serialized as an integer in the JSON object.

For more information on serializing objects to JSON in Java, you can refer to the Gson documentation or other online resources.
