Java Programming, Loose-Leaf Version
- 2. The Integer.parseInt () method requires a String argument, but fails if the String cannot be converted to an integer. Write an application in which you try to parse a String that does not represent an integer value. Catch the Number FormatException that is thrown, and then display an appropriate error message. Save the file as Try ToParseString.java.arrow_forwardusing visual studio and the C# please dont copy the previous answered questions because the solution is incorrect In the Chap07 folder of the Student Sample Programs, you will find a file named ChargeAccounts.txt. The file contains a list of a company’s valid charge account numbers. There are a total of 18 charge account numbers in the file, and each one is a 7-digit number, such as 5658845. Create an application that reads the contents of the file into an array or a List. The application should then let the user enter a charge account number. The program should determine whether the number is valid by searching for it in the array or List that contains the valid charge account numbers. If the number is in the array or List, the program should display a message indicating the number is valid. If the number is not in the array or List, the program should display a message indicating the number is invalidarrow_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_forward
