public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);

    String jsonStr = "{\"name\": \"donut\",\"image\":{\"fname\": \"donut.jpg\",\"w\": 200,\"h\": 200},\"thumbnail\":{\"fname\": \"donutThumb.jpg\",\"w\": 32,\"h\": 32}}";

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

    // To pretty-print, set the EmitCompact property equal to false
    json.put_EmitCompact(false);

    // If bare-LF line endings are desired, turn off EmitCrLf
    // Otherwise CRLF line endings are emitted.
    json.put_EmitCrLf(false);

    // Emit the formatted JSON:
    System.out.println(json.emit());
