Sure, I'd be happy to help you with that! Here's an example of how you can use `Example` in JPA to create an IN condition:
```
// Create a list of values to use in the IN condition
List<String> names = Arrays.asList("John", "Jane", "Bob");
// Create a new Example object for the entity you want to query
Example<Person> example = Example.of(new Person(), ExampleMatcher.matchingAll()
// Use the 'in' method of the ExampleMatcher to specify the property to match on ('name')
.withMatcher("name", ExampleMatcher.GenericPropertyMatcher.of(ExampleMatcher.StringMatcher.IN)));
// Use the Example object as part of your JPA query
List<Person> results = repository.findAll(example);
```
In this example, we're creating an `Example` object for a `Person` entity, and using the `matchingAll()` method to specify that we want to match all properties of the entity. We then use the `withMatcher()` method to specify that we want to match on the `name` property, and use the `IN` matcher to specify that we want to match on a list of values.
Finally, we use the `Example` object as part of a JPA query using the `findAll()` method on our repository.
I hope this helps! Let me know if you have any other questions.
