Use for loop in Java language Write the method stringSplosion().* * The method takes one parameter, a non-empty String str (such as "Code") and* returns a String in the form "CCoCodCode". Notice that this includes the* first character of the original String, followed by the first two characters,* and so on until the whole String is used.* * Examples: stringSplosion("Code") returns "CCoCodCode" stringSplosion("abc")* returns "aababc" stringSplosion("x") returns "x"* * @param str the input String to process.* @return a new String as described above.
Flight assignment runs but there is no imput values for the user to interact when running the program. Kindly fix this issue.import java.util.*; class Flight { String airlineCode; int flightNumber; char type; // D for domestic, I for international String departureAirportCode; String departureGate; char departureDay; int departureTime; String arrivalAirportCode; String arrivalGate; char arrivalDay; int arrivalTime; char status; // S for scheduled, A for arrived, D for departed public Flight(String airlineCode, int flightNumber, char type, String departureAirportCode, String departureGate, char departureDay, int departureTime, String arrivalAirportCode, String arrivalGate, char arrivalDay, int arrivalTime) { this.airlineCode = airlineCode; this.flightNumber = flightNumber; this.type = type; this.departureAirportCode = departureAirportCode; this.departureGate = departureGate;…
Write an application that determines whether a phrase entered by the user is a palindrome. A palindrome is a phrase that reads the same backward and forward without regarding capitalization, spaces or punctuation. And it will allow the user to enter as many phrases as he likes after each iteration.
Java 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…

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).
Instructions: 1. This java program is for an application that stores the author (Writer) data of some books and emails. 2. getAuthors() method get the list of authors and store it in a String array. 3. addAuthors() method is used to add an author anytime for book or email. 4. getDate() method get the date of the book or email. 5. getTitle() method can be used to get the title of the book. 6. getSubject() method is used to get the Subject of the email. 7. getTo() method is used to get the information about the mail to whom it is sent. 8. All get methods need to return the values in the corresponding instance variables. 9. Scanner class can be used to set the data for the variables. The programmer can give his/her own methods to set the instance variables
Python Coding-(On Pycharm Community Edition) Create a mini-lottery with TEXT ticket. The user is going to save three numbers in a text file - those three numbers are from 1-9. In Python, create a program that reads those three numbers from the text file (ticket) Use a random number generator to draw three random numbers Compare the text ticket and the random numbers. If they match number (see below), output the prize The numbers can be in any order the random numbers can be duplicates, so be careful how you count! This work in a similar way to mini-assignment number 48 - but you DO NOT have to write to a text file. Have the user enter the numbers into the text file. Append the numbers read from the text file to a list read each number from the list and compare it to the randomly generated numbers you come up with One number match - free ticket Two numbers match - $2.00 Three numbers match - $10.00 -you don't have to complete bonus, it would be great if you could-…
A MyString Class and a JUMBLE ProgramWhen you play a JUMBLE, you are given a scrambled word that you mustunscramble. For instance, you may be given iedmx and you would be expected to unscramble it to mixed.Write an application that prompts for a list of words and displays four jumbled versions of each word so that you might choose one for creating your own JUMBLE.For example:How many words?3Enter the words:mixedcalendarthenOutput:Here is a list of possible JUMBLEs:mixed calendar theniedmx lendarca hentdixem alecdarn nethmedix randlace entheximd recandla tenhHint: Create a class called MyString that stores and manipulates strings. The oneargument constructor should accept a String argument. The methods shouldinclude:void printme(); // prints the String.andString MyString permute();// returns a permuted version of the String.// This can be done by exchanging random pairs of letters in the String.// If the length of your string is n, then perform 2n swaps

in java 8.8 LAB: Course Grade Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. Assume also the last names and first names do not contain whitespaces. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam. Output the last names, first names, exam…
