- Java please Line is a String object that holds an unknown number of int values separated by spaces. Write a segment of code that computes and displays the sum of the values in line.arrow_forwardFor Java Write an application that prompts a user for two integers and displays every integer between them. Display There are no integers between X and Y if there are no integers between the entered values. Make sure the program works regardless of which entered value is larger. An example of the program is shown below: Enter an integer >> 12 Enter another integer >> 20 The numbers between 12 and 20 include: 13 14 15arrow_forwardProgramming in C#: Write a console-based application that displays every perfect number from 1 through 10000. A number is perfect if it equals the sum of all the smaller positive integers that divide evenly into it. For example, 6 is perfect because 1, 2, and 3 divide evenly into it and their sum is 6. Use format strings(field size 8, right alignment) to show all perfect numbers. Display the results as seen below. 6 28 496 8128arrow_forward
- Write an application that accepts three Strings from the user and displays them in alphabetical order without regard to case.arrow_forwardMicrosoft Visual C# 7th edition, programming Exercise 8-2. I need help, please, thanks. Create a program for Smalltown Regional Airport Flights that accepts either an integer flight number or string airport code from the options in Figure 8-33. Pass the user’s entry to one of two overloaded GetFlightInfo() methods, and then display a returned string with all the flight details. For example, if 201 was input, the output would be: Flight #201 AUS Austin Scheduled at: 0710 (note that there should be two spaces between 'Austin' and 'Scheduled'). The method version that accepts an integer looks up the airport code, name, and time of flight; the version that accepts a string description looks up the flight number, airport name, and time. The methods return a message if the flight is not found. For example, if 100 was input, the output should be Flight #100 was not found. If no flights were scheduled for the airport code entered, for example MCO, the message displayed should be Flight to MCO…arrow_forwardIn java please help with the following: Given a string that contains space separated words, write an application that displays the words in ascending order (If two words are the same, display only one). You need to use the right data structure for storing the words.

Here are two examples of valid input: 7,9,10,2,18,6 8.777,10.9,11,2.2,-18,6 The program should calculate and display the sum of all the numbers. Input Validation 1. Make sure the string only contains numbers and commas (valid symbols are '0'-'9', '-', '.', and ','). 2. If the string is empty, a messages should be displayed, saying that the string is empty.
