     public static void main(String[] args) {
         Object object = new Object();

         Class cls = object.getClass();
         System.out.println(cls);

         try {
         cls=    Class.forName("java.lang.String");
         } catch (ClassNotFoundException e) {
         }
         System.out.println(cls);

         cls = java.lang.String.class;
         System.out.println(cls);
     }
