import java.awt.Toolkit;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.DataFlavor;
import java.awt.datatransfer.Transferable;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.Reader;

public class Main {
  public static void main(String[] args) {
    System.out.println(getClipboardData());
  }

  public static String getClipboardData() {
    String result = "";
    Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();

    Transferable contents = clipboard.getContents(null);
    DataFlavor dfRTF = new DataFlavor("text/rtf", "Rich Formatted Text");
    DataFlavor dfTxt = DataFlavor.stringFlavor;

    boolean hasTransferableRTFText = (contents != null)
        && contents.isDataFlavorSupported(dfRTF);

    boolean hasTransferableTxtText = (contents != null)
        && contents.isDataFlavorSupported(dfTxt);

    if (hasTransferableRTFText) {
      try {
        result = streamToString((InputStream) contents.getTransferData(dfRTF));
      } catch (Exception ex) {
        ex.printStackTrace();
      }
    } else if (hasTransferableTxtText) {
      try {
        result = (String) contents.getTransferData(dfTxt);
      } catch (Exception ex) {
        ex.printStackTrace();
      }
    }
    return result;
  }

  private static String streamToString(InputStream transferData) {
    return slurp(transferData, 1024);
  }

  public static String slurp(final InputStream is, final int bufferSize) {
    final char[] buffer = new char[bufferSize];
    final StringBuilder out = new StringBuilder();
    try {
      final Reader in = new InputStreamReader(is, "UTF-8");
      try {
        for (;;) {
          int rsz = in.read(buffer, 0, buffer.length);
          if (rsz < 0)
            break;
          out.append(buffer, 0, rsz);
        }
      } finally {
        in.close();
      }
    } catch (Exception ex) {
    }
    return out.toString();
  }
