What is difference between Edit validate and Edit Input rules?

ANS: 
Edit Validate : Use edit validate rule to validate the property value using java code. Edit validate rules can be used property-validate, Rule-Obj-Validate and Property rules.

Edit Input : Edit input rules converts user entered data into required format. For example is the user enters date MM/DD/YYYY format, edit input rule coverts this date into DD-MMM-YYYY (required format). Again we need to write java code for this transformation.
