Carly’s Catering provides meals for parties and special events. In previous chapters, you have developed a class that holds catering event information and an application that tests the methods using four objects of the class. Now modify the Event and EventDemo classes as follows: Modify the method that sets the event number in the Event class so that if the argument passed to the method is not a four-character String that starts with a letter followed by three digits, then the event number is forced to A000. If the initial letter in the event number is not uppercase, force it to be so. Add a contact phone number field to the Event class. Add a set method for the contact phone number field in the Event class. Whether the user enters all digits or any combination of digits, spaces, dashes, dots, or parentheses for a phone number, store it as all digits. For example, if the user enters (920) 872-9182, store the phone number as 9208729182. If the user enters a number with fewer or more…

(3) Write a C# .NET Core Console App that asks the user to enter a number and then displays a string with the original number followed by the reverse of the number. For example, if the user entered 123 as an int you program should create a string "123321" and display it on the screen

1. A showChar MethodWrite a method named showChar. The method should accept two arguments: a reference toa String object and an integer. The integer argument is a character position within theString, with the first character being at position 0. When the method executes, it shoulddisplay the character at that character position. The method does not return anything.Here is an example of a call to the method:showChar("New York", 2);In this call, the method will display the character w because it is in position 2. Demonstratethe method in a complete program-- use the class name Method_showChar   Java
