# Issue a Token (Java sample code)
This code demonstrates how to issue a (fungible) token on the XRP Ledger. For a detailed explanation, see <https://xrpl.org/issue-a-fungible-token.html>.
The easiest way to run this code is from an IDE such as IntelliJ. For an example `pom.xml` file, see [Get Started Using Java](https://xrpl.org/get-started-using-java.html).
