         while((value=car.read())!=-1)
         {
            
            // convert integer to char
            char c = (char)value;
            
            // print characters
            System.out.print(c + " ");
         }
         
         // reset invoked
         car.reset();
         System.out.println("\nReset() invoked");
         
         // read till the end of the stream
         while((value=car.read())!=-1)
         {
            
            // convert integer to char
            char c = (char)value;
            
            // print characters
            System.out.print(c + " ");
         }
      }catch(IOException e){
         
         // if I/O error occurs
         e.printStackTrace();
      }finally{
         
         // releases any system resources associated with the stream
         if(car!=null)
            car.close();
      }
   }
}

Let us compile and run the above program, this will produce the following result:

A B C D E 
Reset() invoked
A B C D E
