What is a transaction rollback in Java?

A transaction rollback in Java is a mechanism to revert a transaction to its previous state in case of an error.

When should I use a rollback?

You should use a rollback when an operation fails, ensuring data integrity by undoing any changes made during the transaction.

Can you give me an example of how to implement it?

Sure! In Java, you can use the Connection object to call rollback() within a try-catch block to handle exceptions.

What happens if I don't use rollback?

If you don't use rollback, any changes made during the transaction will be committed, potentially leading to data inconsistency.
