### Question:
BitcoinURI { @Override public String toString() { StringBuilder builder = new StringBuilder("BitcoinURI["); boolean first = true; for (Map.Entry<String, Object> entry : parameterMap.entrySet()) { if (first) { first = false; } else { builder.append(","); } builder.append("'").append(entry.getKey()).append("'=").append("'").append(entry.getValue().toString()).append("'"); } builder.append("]"); return builder.toString(); } BitcoinURI(String uri);  BitcoinURI(@Nullable NetworkParameters params, String input); @Nullable Address getAddress(); BigInteger getAmount(); String getLabel(); String getMessage(); String getPaymentRequestUrl(); Object getParameterByName(String name); @Override String toString(); static String convertToBitcoinURI(Address address, BigInteger amount, String label, String message); static String convertToBitcoinURI(String address, @Nullable BigInteger amount, @Nullable String label,
                                             @Nullable String message); static final String FIELD_MESSAGE; static final String FIELD_LABEL; static final String FIELD_AMOUNT; static final String FIELD_ADDRESS; static final String FIELD_PAYMENT_REQUEST_URL; static final String BITCOIN_SCHEME; }### Answer:
