Note: As dumpwallet and dumpprivkey have been used by scammers, we have introduced a safety net to these commands. Please refer to the relevant Pull Request.

You can export the private key that belongs to a specific address in wallet with the command dumpprivkey followed by the target address.

You can import a private key into the wallet with the command importprivkey followed by the target private key.

If you try to import the private key again, the wallet will display an error message indicating that you already imported the private key into the wallet.
