## Java
The `java` module shows the currently installed version of Java.
The module will be shown if any of the following conditions are met:
- The current directory contains a `pom.xml` or `build.gradle` file
- The current directory contains a file with the `.java`, `.class` or `.jar` extension
### Options
| Variable | Default | Description |
| ---------- | -------------- | -------------------------------------------------------- |
| `symbol` | `"☕ "` | The symbol used before displaying the version of Java. |
| `style` | `"dimmed red"` | The style for the module. |
| `disabled` | `false` | Disables the `java` module. |
### Example
```toml
# ~/.config/starship.toml
[java]
symbol = "🌟 "
```
