### Question:
SystemUtils { public static File[] getClassPathFiles() { String classPath = System.getProperty("java.class.path"); if (classPath == null) { return new File[0]; } StringTokenizer st = new StringTokenizer(classPath, File.pathSeparator); File[] files = new File[st.countTokens()]; try { for (int i = 0; i < files.length; i++) { files[i] = new File(st.nextToken()); } } catch (NoSuchElementException e) { } return files; }  static String getUserName(); static File getUserHomeDir(); static String getApplicationHomepageUrl(); static File getApplicationDataDir(); static File getApplicationDataDir(boolean force); static String getApplicationContextId(); static String getApplicationName(); static File getCurrentWorkingDir(); static File[] getClassPathFiles(); static File getApplicationHomeDir(); static String getApplicationHomePropertyName(); static File getApplicationHomeDir(final URL url); static String getClassFileName(final Class aClass); @Deprecated static File getBeamHomeDir(); static File getDefaultBeamCacheDir(); static String convertToLocalPath(String urlPath); @Deprecated static void deleteFileTree(File treeRoot); static String createHumanReadableExceptionMessage(final Exception e); static void copyToClipboard(final String text); static void copyToClipboard(final Image image); static boolean isRunningOnMacOS(); static Iterable<S> loadServices(Class<S> serviceType); static Iterable<S> loadServices(Class<S> serviceType, ClassLoader classLoader); static String getBuildNumber(); static int getLogLevel(String logLevelStr); @Deprecated static Class<?> loadHdf4Lib(Class<?> callerClass); @Deprecated static Class<?> loadHdf5Lib(Class<?> callerClass); static void init3rdPartyLibs(ClassLoader cl); static String getApplicationRemoteVersionUrl(); @Deprecated
