### Best Practices

**Null Safety:**
```java
public Suggester(final Client client, final SuggestSettings settings) {
    this.client = Objects.requireNonNull(client, "client must not be null");
    this.settings = Objects.requireNonNull(settings, "settings must not be null");
}
```

**Logging with Context:**
```java
if (logger.isInfoEnabled()) {

package lifecycle

import (
	"encoding/xml"
	"io"

	"github.com/minio/minio-go/v7/pkg/tags"
)

var errInvalidFilter = Errorf("Filter must have exactly one of Prefix, Tag, or And specified")

// Filter - a filter for a lifecycle configuration Rule.
type Filter struct {
	XMLName xml.Name `xml:"Filter"`
	set     bool

	Prefix Prefix

public enum CollectionFeature implements Feature<Collection> {

   * The collection must not throw {@code NullPointerException} on calls such as {@code
   * contains(null)} or {@code remove(null)}, but instead must return a simple {@code false}.
   */
  ALLOWS_NULL_QUERIES,
  ALLOWS_NULL_VALUES(ALLOWS_NULL_QUERIES),

  /**

   *  * [OkHttpClient.authenticator] must respond to an authorization challenge.
   *
   * @param networkResponse the intermediate response that may require a follow-up request.

If you open a GitHub Issue, here is our policy:

1.  It must be a bug/performance issue or a feature request or a build issue or
    a documentation issue (for small doc fixes please send a PR instead).
1.  Make sure the Issue Template is filled out.
1.  The issue should be related to the repo it is created in.

**Here's why we have this policy:** We want to focus on the work that benefits
the whole community, e.g., fixing bugs and adding features. Individual support
