    try {
        System.loadLibrary("chilkat");

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

    // To URL encoding a string:
    String s = "Why a > b?";

    CkStringBuilder sb = new CkStringBuilder();
    success = sb.Append(s);

    // URL encode the string.
    sb.Encode("url","utf-8");

    // Show the URL encoded string:
    String sEncoded = sb.getAsString();
    System.out.println(sEncoded);

    // The result is:  Why%20a%20%3E%20b%3F

    // If you prefer "+" instead of "%20" for SPACE chars:
    int numReplaced = sb.Replace("%20","+");
    System.out.println(sb.getAsString());

    // Output is:   Why+a+%3E+b%3F

    // To decode:
    sb.Decode("url","utf-8");
    System.out.println(sb.getAsString());

    // Result is: Why a > b?
