How to through the secret key or mnemonic words change the password, I find for a long time, didn't find the corresponding API

Hi,
Assuming that you already have the private key, you can simply create a new wallet file with the private key.
E.g:

ECKeyPair keypair = ECKeyPair.create(YOURPRIVATEKEY);
WalletUtils.generateWalletFile("SUPERSAFENEWPASSWORD", keypair,new File(WALLETSAVEPATH), true)
