B) By using the @JsonProperty annotation

C) By using the @JsonIgnore annotation

D) By setting a flag in the JSON

Answer:

A) By using the @JsonFormat annotation

Explanation:

In Jackson, you can handle date formatting by using the @JsonFormat annotation. This annotation allows you to specify the format in which date and time fields should be serialized and deserialized.

For example:


public class SomeClass {
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd")
    private Date date;
    // other fields
}

In this example, the date field will be serialized and deserialized in the “yyyy-MM-dd” format, ensuring consistent and readable date formats in the JSON output.
