### Question:
PeercoinURI { @Override public String toString() { StringBuilder builder = new StringBuilder("PeercoinURI["); 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(); } PeercoinURI(String uri);  PeercoinURI(
        NetworkParameters params, String input, @Nullable String prefix
    );  PeercoinURI(NetworkParameters params, String input); @Nullable Address getAddress(); Monetary getAmount(); String getLabel(); String getMessage(); String getPaymentRequestUrl(); List<String> getPaymentRequestUrls(); Object getParameterByName(String name); @Override String toString(); static String convertToPeercoinURI(Address address, Coin amount, String label, String message); static String convertToPeercoinURI(
        String address, @Nullable Coin 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[] PEERCOIN_SCHEMES; static final String PREFERED_PEERCOIN_SCHEME; }### Answer:
@Test public void testGood_Combinations() throws PeercoinURIParseException { testObject = new PeercoinURI(MainNetParams.get(), PeercoinURI.PREFERED_PEERCOIN_SCHEME + ":" + MAINNET_GOOD_ADDRESS + "?amount=6543210&label=Hello%20World&message=Be%20well"); assertEquals( "PeercoinURI['amount'='6543210000000','label'='Hello World','message'='Be well','address'='PKf1PvTHnNncWTigggeXPnt5GH6LuDsnM4']", testObject.toString()); }
