`@Validated` is a Spring framework annotation used to enable validation on method parameters and return values. When a method is annotated with `@Validated`, Spring will validate the input arguments of the method before executing it. If the input arguments are not valid, a `MethodArgumentNotValidException` will be thrown.
Here is an example of using `@Validated` to validate a list of objects:
```java
public void processList(@Validated List<MyObject> list) {
// Code to process the list
}
```
In this example, `MyObject` is a custom class that has validation constraints defined using annotations such as `@NotNull`, `@Size`, etc. When the `processList` method is called, Spring will validate each object in the list to ensure that it meets the defined constraints. If any object fails validation, a `MethodArgumentNotValidException` will be thrown.
