  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);

  public static void main(String argv[])
  {
    boolean success = false;

    CkJsonObject json = new CkJsonObject();

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

    success = json.Load(jsonStr);
    if (success != true) {
        System.out.println(json.lastErrorText());
        return;
        }

    int numMembers = json.get_Size();
    int i;
    for (i = 0; i <= numMembers - 1; 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
