        int length = OS.GetWindowTextLength(handle);
        if(length == 0) return "";
        /* Use the character encoding for the default locale */

        OS.GetWindowText(handle, buffer, length + 1);
        return buffer.toString(0, length);
    }

public static final void main(String[] args) {
    try {
        Thread.sleep(1000L);
    } catch(InterruptedException e) {
        Thread.currentThread().interrupt();
    }
    System.out.println(getActiveWindowText());
}
