Program Plan Intro
Exception:
An exception is a problem that creates during the execution of a program; it offers a method to transfer control from one part to another part of a program.
An exception handling is created by using the following three keywords such as try, catch and throw.
- The “try” block have the program for the basic
algorithm that says the computer what to do when all goes well. - The “throw” keyword throws an error statement to the “catch” block.
- The “catch” block will catch the exception or handling the exception.
Generally, the compiler executes “try” block. In the “try” block, if the statements cause an exception, it throws an error statement to the “catch” block using the keyword “throw”. The “catch” block then handles the error based upon the type of exception.

Write a program that will ask user to enter CNIC number without dashes. It must throw exception if user enters invalid number. For example it must throw exception if CNIC number is not 13 digit. It should also throw exception if user input other than digits. You must use try, catch, throw.
What output is produced by the following code?int waitTime = 46;try{cout << "Try block entered.\n";if (waitTime > 30)throw waitTime;cout << "Leaving try block.\n";}catch(int thrownValue){cout << "Exception thrown with\n"<< "waitTime equal to " << thrownValue << endl;}cout << "After catch block" << endl;
in java
Write a program that reads integers userNum and divNum as input, and output the quotient (userNum divided by divNum). Use a try block to perform the statements. Use a catch block to catch any ArithmeticException and output an exception message with the getMessage() method. Use another catch block to catch any InputMismatchException and output an exception message with the toString() method.
Note: ArithmeticException is thrown when a division by zero happens. InputMismatchException is thrown when a user enters a value of different data type than what is defined in the program. Do not include code to throw any exception in the program.
Ex: If the input of the program is:
15 3
the output of the program is:
5
Ex: If the input of the program is:
10 0
the output of the program is:
Arithmetic Exception: / by zero
Ex: If the input of the program is:
15.5 5
the output of the program is:
Input Mismatch Exception: java.util.InputMismatchException

Write a Java program to read the Student ID and GSM Number of a student. Use a method called ValidityDetails () for checking the validity of details entered. If the Student ID doesn’t start with the characters ST and contains more than 6 letters or if the Mobile Number does not contain exactly 8 digits, throw a user defined exception InvalidDetailsException.

- This code is in Python As you know, when you attempt to get a number from the user by usingsomething like:number = int(input(“Enter a number”) ornumber = float(input(“Enter a number”),if the user includes commas or a dollar sign in the number, the conversion will failwith an exception.Write a program that will include and use a function called getNumber( prompt )that will do the following:1) Use the standard input function to display the prompt and get the user’sinput.2) Use the string functions to remove any commas or dollar sign from theinput.3) Check for the presence of a decimal point.4) If a decimal point is present, use the float conversion function to convertthe modified input to float; otherwise, use the int conversion function toconvert to an int5) Return the number to the calling code.arrow_forwardQ1) The following snippet of code inputs an integer and outputs it:int num=0;Scanner kbd = new Scanner(System.in);num = kbd.nextInt();System.out.println(num);Run this program but enter text instead of an integer.

Add a loop so the user must enterthe number again if text is entered.Q2) The following class maintains an account balance and returns a special error code.public class Account{private double balance;// returns new balance or -1 if errorpublic double deposit(double amount){if (amount > 0)balance += amount;elsereturn -1; // Code indicating errorreturn balance;}}Rewrite the class so that it throws appropriate exception instead ofreturning -1 as an error code.

Write a program that converts dates from a numerical month-day format to alphabetic month-day format. IE 1/31 or 01/31 would have an output of January 31. 1. User enters the month and day as a single string. It is then converted. (10%) 2. Create 2 exception classes (20%) 1. MonthException thrown for invalid months 2. DayException-thrown for invalid days for the given month 3. You can assume Feb is always 28 days 2. This should run in a for loop and end when a user is done entering dates (70%)arrow_forwardC++ You did this way back in Unit 1! But now all of your RomanNumber code is wrapped up in a class, so the "main" program is short and sweet. As before, write a program that accepts entries from the user. If it's an integer, convert to Roman Number and display. If it's a Roman Number, convert to integer and display. If it's neither, thrown an exception and continue to process The action to take here will be to display an error message If the entry is 0 or O (The digit 0 (zero) or the letter O) exit and state how many conversions were done of each type (integer to Roman and Roman to integer) and how many exceptions were thrown. As I said, the main program will be short and sweet. Provide your .cpp code and a screen shot of your program in action. Enter twelve conversions - four integer to Roman, four Roman to integer, and two of each in which the input is invalid so that I can see the exceptions. The thirteenth and final entry will be 0 or O.arrow_forward

Write the code to handle the following exceptions: If the user enters a negative number, throw and catch an error that gives the user the appropriate message and request a valid number. Do this until the user enters a valid number If the user enters a character, throw and catch an error that indicates the input stream is invalid. Write code that resets the input stream and request a valid number. Do this until the user enters a valid number d.
