### Question:
AtlasUtil { public static String getUriDataType(String atlasUri) { List<String> uriA = AtlasUtil.getUriPartsAsArray(atlasUri); if (uriA == null || uriA.size() < 3 || isEmpty(uriA.get(2))) { return null; } return uriA.get(2); }  static Properties loadPropertiesFromURL(URL url); static boolean isEmpty(String string); static boolean matchUriModule(String uriA, String uriB); static String getUriScheme(String atlasUri); static String getUriModule(String atlasUri); static String getUriDataType(String atlasUri); static String getUriModuleVersion(String atlasUri); static String getUriParameterValue(String atlasUri, String key); static Map<String, String> getUriParameters(String atlasUri); static int countCharacters(String text, char match); static List<Class<?>> findClassesForPackage(String scannedPackage); static void addAudit(AtlasSession session, String docId, String message, String path, AuditStatus status,
            String value); static Audit createAudit(AuditStatus status, String docId, String docName, String path, String value, String message); static void addAudit(AtlasSession session, Validation validation); static void addAudits(AtlasInternalSession session, String docId, List<Audit> audits); static AuditStatus toAuditStatus(ValidationStatus vstatus); static String getDocumentNameById(AtlasMapping mapping, String docId); static String getChainedMessage(Throwable t); static String escapeForUri(String source); static String unescapeFromUri(String uri); static void deleteDirectory(File targetDir); static void deleteDirectoryContents(File targetDir); static void copyFile(Path sourcePath, Path destPath); static final int SPLIT_LIMIT; static final String NEW_LINE_CHARS; }### Answer:
@Test public void testGetUriDataType() { assertEquals("util", AtlasUtil.getUriDataType("atlas:java:util?param1=value1&param2=value2")); }
