What is the functionality of the myMethod () and how many times the result is set to true? A. Checks Anagrams for a palindrome and 8. B. Checks Combinations for a palindrome and 8. C. Checks palindrome and 8. D. Randomly reverses the string and 8.

In Java MailBox- client:String- emails: Email[]- actualSize: int+ Mailbox()+ Mailbox(client:String)+ getClient(): String+ getEmail(int index): Email+ getActualSize(): int+ addEmail(email: Email): void+ sortEmailsByDate(): void+ findEmail(year:int: Email+ countUrgent():int+ toString(): String Write java code for all the methods shown on the class diagram. Below arethe details needed for the different methods:a. The default constructor will assign the client a default name (any value ofyour choice). Keep in mind that a single mailbox (e.g., gmail) can handle amaximum of 15 emails, but it can hold less, which is the actual size of theemails array. So, the constructor should instantiate the emails arrayinstance variable by creating an array of size 15. It should also set theactualSize variable to 0.b. The MailBox (String client) constructor should call the default constructorusing chaining. It should then initialize the client variable using the clientparameter.c. The toString method…
In this assignment, you will implement a simple class called CustomString. This class represents a more customizable version of a String, with additional attributes and methods. For example, the CustomString class has a “reverse” method which returns a new string version of the current string where the capitalization is reversed (i.e., lowercase to uppercase and uppercase to lowercase) for the alphabetical characters specified in a given argument. For CustomString “abc, XYZ; 123.”, calling reverse("bcdxyz@3210.") will return "aBC, xyz; 123.". The CustomString class also has a “remove” method which returns a new string version of the current string where the alphabetical characters specified in a given argument, are removed. For CustomString "my lucky numbers are 6, 8, and 19.", calling remove("ra6") will return "my lucky numbers e 6, 8, nd 19.". There are 5 methods that need to be implemented in the CustomString class: getString() - Returns the current setString(String string)…
