You can generate an IOTA address using the
    [`GetAddressesBuilder`](./../libraries/java/api_reference#getaddressesbuilder) helper class and calling the    `GetAddressesBuilder::from(seed: &str)` function
and respective chaining calls that will return a list of tuples with the generated addresses. You can find more information
on the parameters in the [Address/Key Space section](../../../explanations/address_key_space.md).

The whole process is deterministic. This means the output is the same as long as the seed is the same:

<CodeBlock className="language-java">
    {generate_addresses}
</CodeBlock>

**Output example**:

```string
[
  'atoi1qz6dr6dtl0856tf0pczz7gesrf7j8a4vr00q58ld2zx7ttlv3p96snpym9z',
  'atoi1qpp7sz28a0ghvd6knwnljr7j2s04qquduuc5vlz94fwf94zznj2yv5ew2c4',
  'atoi1qzje6zhg5vu456eg3z84ekcfn3laxqyczche5eeqhcdh3w9yr5sqvr4z4td',
  'atoi1qqwhxjmcvmatpedeedapgx0vwyupfwx9k5n4w0lnc5l6vmz78aavwhs55v0',
  'atoi1qzg63t9880jtfysvpq7rrynz0rqt3kd2fw8r4934ezraz9dpwvzxkw2dtmh'
]
```

IOTA addresses are represented by a checksumed base-32 string (Bech32). You can find a detailed explanation in the
[Chrysalis documentations](https://wiki.iota.org/chrysalis-docs/guides/developer/#iota-15-address-anatom), but here are
parts relevant to this example:

* If an address starts with `atoi` then it means it is related to `devnet`. `iota` stands for `mainnet`.
* Number `1` at the 5<sup>th</sup> position is just a separator.
* The last 6 characters are reserved for a checksum.

Addresses can be also represented in a hex format using the
    [`Client.bech32ToHex(bech32)`](./../libraries/java/api_reference#bech32tohexbech32-string) function.

If you want to quickly validate any IOTA address, you can use the
[`Client.isAddressValid()`](./../libraries/java/api_reference#isaddressvalidaddress-boolean) function that returns a `bool` value. You should
perform a sanity check on address before using it.
