### Question:
GUIDGenerator { public static long createLongTypeGUID(){ return createLongTypeGUID(32); }  static String createStringTypeGUID(); static long createLongTypeGUID(); static long createLongTypeGUID(int ipDigits); static long createLongTypeGUIDBySvrId(int svrId);  }### Answer:
@Test public void testCreateLongTypeGUIDBasic() throws Exception { System.out.println(SystemUtils.getLocalAddress().getHostAddress()); for (int i = 0; i < 10; i++) { long guid = GUIDGenerator.createLongTypeGUID(); System.out.println(Long.toBinaryString(guid) + ' ' + guid); } System.out.println(); for (int i = 0; i < 10; i++) { System.out.println(Long.toBinaryString(GUIDGenerator.createLongTypeGUID(24))); } System.out.println(); for (int i = 0; i < 100; i++) { System.out.println(Long.toBinaryString(GUIDGenerator.createLongTypeGUID(16))); } }
