### Question:
Paths { public static String getNameOf(String path) { int i = path.lastIndexOf(DELIM); if (i == -1 || path.length() == 1) return path; return path.substring(i + 1); }  static String getNameOf(String path); static String getParentOf(String path); static String appended(String path, String child); static String renamed(String path, String newName); static String reparented(String path, String newParentPath); static String relativeIfUnder(String path, String root); static Iterable<String> split(String path); static boolean isParent(String parent, String path); static boolean isParentOrChild(String p1, String p2); static boolean equals(String p1, String p2); static void setCaseSensitive(boolean b); static boolean isCaseSensitive(); static void useSystemCaseSensitivity(); static final char DELIM; }### Answer:
@Test public void testName() { assertEquals("file", Paths.getNameOf("file")); assertEquals("file", Paths.getNameOf("dir/file")); assertEquals("/", Paths.getNameOf("/")); }
