Considering the following painless script.  
"dateadddays" :{  
"script" :{  
"lang": "painless",  
"source" : "int days = 5; long millis = 5 \* 24 \* 3600 \* 1000; long totalmillis = doc.born.value.millis + millis; SimpleDateFormat sdf = new SimpleDateFormat('dd-M-yyyy hh:mm:ss'); Calendar cal = Calendar.getInstance(); cal.setTimeInMillis(totalmillis); return sdf.format(cal.getTime());"  
}  
}

is there a way to store objects such as  
SimpleDateFormat sdf = new SimpleDateFormat('dd-M-yyyy hh:mm:ss');

And use it in the multiple scripts.

Unfortunately there is no way to share anything across invocations (per document) in a scoring script.

Also, note that that your example can be done much more simply with the java time api. Here I used an existing ISO format, but you could also use `DateTimeFormatter.ofPattern('dd-M-yyyy hh:mm:ss')` to get your exact format if it is important.

```auto

Instant time = Instant.ofEpochMill(doc.born.value.millis).plus(Duration.ofDays(5));
return DateTimeFormatter.ISO_LOCAL_DATE_TIME.format(time);

```

thanks.  
Can we share using stored scripts ?

storing the following script  
SimpleDateFormat sdf = new SimpleDateFormat('dd-M-yyyy hh:mm:ss');

and reading as params ?  
i am getting the following exception  
"lang": "painless",  
"caused\_by": {  
"type": "class\_cast\_exception",  
"reason": "java.util.HashMap cannot be cast to java.text.SimpleDateFormat"  
}

can i specify the params type ?
