- 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…Create integer ArrayList. Ask user input for integer, which is used to append the elements for that number of times. Create a Java method named "repetition" which will pass two parameters – ArrayList and integer entered by user. In the method, elements are replicated for the number of times based on the value of the integer. For example, If you have an ArrayList with the values [21,25, 5] and the user inputs 3, the repetition method should print the value -- [21,25, 5,21,25,5,21,25,5]Step 1: Implement the getSortedRunLength() method Implement the getSortedRunLength() method in NaturalMergeSorter.java. Access NaturalMergeSorter.java by clicking on the orange arrow next to NaturalMerge.java at the top of the coding window. getSortedRunLength() has three parameters: array: a reference to an array of integers, arrayLength: an integer for the array's length, and startIndex: an integer for the run's starting index. The method returns the number of array elements sorted in ascending order, starting at startIndex and ending either at the end of the sorted run, or the end of the array, whichever comes first. The method returns 0 if startIndex is out of bounds. File NaturalMerge.java has several test cases for getSortedRunLength() that can be run by clicking the "Run program" button. One test case also exists for naturalMergeSort(), but that can be ignored until step two is completed. The program's output does not affect grading. Submit for grading to ensure that the…
- Write a full program to create this following linkedlist and display it, then display only the EVEN numbers. You need to write the classes and only 3 method to insert,display and display the even numbers. (in java)create an array of 3 Circle object references with radius = 1, 2 and 3 respectively. it should look like: Circle: radius = 1.00 area = 3.14 circumference = 6.28 then create one Circle reference called circle here. Assign 3 radii to the object: 10, 12 and 14 respectively. Print out should look like Circle: radius = 10.00 area = 314.16 circumference = 62.83Define a class named Element with the following private data fields: String name; // The name of the chemical element int atomicNumber; // The atomic number of the element double atomicWeight; // The atomic weight of the element Override the toString() and equals() methods for the class with methods you design. Define a Java HashMap named elements that uses the String value of a chemical symbol as the key and an instance of the Element class as the value. For example, the chemical symbol for Carbon is the letter “C”. The atomic number of Carbon is 6, and the atomic weight of Carbon is 12.011. To add Carbon to the HashMap named elements, first create an instance of the Element class using “Carbon”, 6, and 12.011. Then add an entry to the HashMap collection using “C” as the key and the Element object as the value.

- Java Exercise: Given the starter code consisting of ListOfNodes.java and Node.java, complete the implementation of all the methods in ListOfNodes.java without changing the code in Node.java or main(). You should start by commenting all the lines in main and gradually implement the methods then run the code after each method comparing the real output to the expected out listed here. The following are some rules and guidelines you must follow:a. Read all the methods and decide if some of them will call on othersb. Reuse methods whenever possiblec. You are encouraged to write private helper methodsd.
