Is there an equivalent to keccak256(abi.encode(*some address*)) in web3j?

[andras-ballai]

I'm working with the t-rex token standard and it'd nice to have a java implementation of keccak256(abi.encode(*some address*)) instead of having to create (and deploy) a smart contract just for this

You mean this -

/**
     * Keccak-256 hash function.
     *
     * @param hexInput hex encoded input data with optional 0x prefix
     * @return hash value as hex encoded string
     */
    public static String sha3(String hexInput) {
        byte[] bytes = Numeric.hexStringToByteArray(hexInput);
        byte[] result = sha3(bytes);
        return Numeric.toHexString(result);
    }
