Notification annotations

Report a typo

Imagine you need to set the following constraints for the Notification class:

title cannot be empty,
content length cannot be longer than 50 symbols,
messages list can contain from 1 to 5 messages,
textColor can have the next values: "R", "G", "B".

Match the fields and the corresponding annotations:

Java

public class Notification {

    {1}
    private String title;

    {2}
    private String content;
    
    {3}
    private List<Message> messages;

    {4}
    private String textColor;

    // getters and setters
}

Kotlin

class Notification(

    {1}
    var title: String,

    {2}
    var content: String,

    {3}
    var messages: List<Message>,

    {4}
    var textColor: String

)

Match the items from left and right columns

@Pattern(regexp = "[RGB]")

@NotEmpty

@Size(min = 1, max = 5)

@Size(max = 50)
