public class ChilkatExample {

    public static void main(String[] args) {
        JsonObject json = new JsonObject();

        String jsonStr = "{ \"id\": 1, \"name\": \"A green door\", \"tags\": [\"home\", \"green\"], \"price\": 125 }";

        try {
            json.load(jsonStr);

            System.out.println(e.getLastErrorText());

        int numMembers = json.getSize();
        for (int i = 0; i < numMembers; i++) {
            String name = json.nameAt(i);
            String value = json.stringAt(i);

            System.out.println(name + ": " + value);

            int iValue = json.intAt(i);
            System.out.println(name + " as integer: " + iValue);
        }

        // Note: The StringAt method returns the value as a string regardless of the type.
        // If the value is a JSON array (such as for ["home", "green"]), then the JSON encoding
        // of the entire array is returned.

        // The IntAt method returns the value as an integer.  If the value does not convert to
        // an integer, then 0 is returned.
