### Question:
DataTypeUrl { @Override public String toString() { return PROTOCOL + ":/" + dataTypeManagerId.toString() + "?uid=" + Objects.toString(dataTypeId, "") + "&name=" + dataTypeName; } DataTypeUrl(DataType dt);  DataTypeUrl(String url); UniversalID getDataTypeManagerId(); UniversalID getDataTypeId(); String getDataTypeName(); DataType getDataType(DataTypeManagerService service); @Override int hashCode(); @Override boolean equals(Object obj); @Override String toString();  }### Answer:
@Test public void testToString() { String dtmId = "3295333330922457057"; String dtId = "3295333330922457056"; String name = "string"; String urlString = "datatype:/" + dtmId + "?uid=" + dtId + "&name=" + name; DataTypeUrl dtUrl = new DataTypeUrl(urlString); assertEquals(urlString, dtUrl.toString()); }
