- Define Writeline method.Programming: C LanguageBasic Java Help Each year, the Social Security Administration provides a list of baby names for boy and girls by state. You will write a program to read a file containing a list of baby names and display the top names. To start, implement the following class: baby names util = printTopNames(File, int): void printTopNames Will be a static method. It will accept two parameters, one is a File containing the list of names. The other is an integer that indicates how many names to display (ie, top 10 names, or top 50 names, etc). The integer argument could be any valid integer. You do not have to worry about an integer value large than 5 for the boy/girl names. This method should open the file and parse the file and print the names as shown below: Your program will use the Scanner class to read the data from the file (see your text for examples). You will also need to use a delimiter with the scanner so that the scanner will break the line apart based on the commas. For this file, set…
- comparison methods that can be useful when working withstrings are StartsWith and EndsWith. These instance methods take a stringas an argument and return True if the instance either starts with or ends withthe string argument.Write two short programs that demonstrate the use of these methods. First, we’ll demonstrate the EndsWith method:(use c#)Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).Write in Java please
- CcxxJava Constructor(String) This constructor will take a string of digits(no commas) and turn it into an UnboundedInt object (MUST BE STRING INPUT) UnboundedInt add (UnboundedInt ) A method that adds the current UnboundedInt with a passed in one. The return is a new UnboundedInt. UnboundedInt multiply (UnboundedInt ) - do this one last! A method that multiplies the current UnboundedInt with a passed in one. The return is a new UnboundedInt. void addEnd ( int ) -optional method (helpful) A method to add a new element at the end of the sequence , used for building up each higher term in a single sequence. (i.e. adding a new IntNode to the linked list) UnboundedInt clone( ) a method that returns a copy of the original structure boolean equals ( Object ) a method that returns true if linked list represents the same numerical number as the input parameter. False otherwise. Overrides method in Object class. String toString ( ) creates a string of all elements…C++: Create a basic contact book where you can store and then retrieve contact information.The information that (at least) should be able to be stored is name (postal) address e-mail address telephone number Birthday, other. It should work as follows. The user should be able to choose what he wants to do, for example : add contact or find the phone number of a given contact. There are several ways to implement this, for example: • To have a menu where the user can choose by entering a number corresponding to one of the menu options. Exit should be one of the options. • where the user gives commands for what to do. The functionality that must exist is • to add a contact, • to delete a contact, • to search for a contact. The contact book should be saved in a file so that it does not disappear between runs of the program.
