Cancel pending transaction (bitcoinj)

Question

I'm using bitcoincashj (https://github.com/bitcoinj-cash/bitcoinj) I created a transaction and sent it. But it didn't broadcasted to network. Can I cancel this transaction?

Current wallet status is:

Answer 1

If your transaction wasn't broadcast, it never happened. You can simply use the inputs in another transaction.
