Q) What is Batch updates?



A)
->Batch updates is a formality given by JDBC using which, DML SQL statement can be grouped physically into one unit and at a time submitted to the DBMS for processing as a batch.

ATM application is an example for OLTP.
->At the end of every month, all accounts must be created by their earned interest is an example use case of batch processing.

Ex: class D {        static c        {                      } //nested class, but not an inner class , because of static class. } //outer class. ->we have three different kinds of inner classes. 1) Member inner class 2) Meth...
