Function findID() has two parameters: a student's name (string) and the text file's contents (infile, input file variable). The function findID() returns the ID associated with the student's name if the name is in the file, otherwise the function throws a runtime error with the message "Student ID not found for studentName", where studentName is the name of the student.
Function findName() has two parameters: a student's ID (string) and the text file's contents (infile). The function findName() returns the name associated with the student's ID if the ID is in the file, otherwise the function throws a runtime error with the message "Student name not found for studentID", where studentID is the ID of the student.
The main program takes three inputs from a user: the name of a text file (string), the search option for finding the ID or name of a student, and the ID or name of a student (string). If the search option is false, findID() is invoked with the student's name as an argument. If the search option is true, findName() is invoked with the student's ID as an argument. The main program outputs the search result or the caught exception message.
Ex: If the input of the program is:
roster.txt 0 Reagan
and the contents of roster.txt are:
Reagan rebradshaw835
Ryley rbarber894
Peyton pstott885
Tyrese tmayo 945
Caius ccharlton329
the output of the program is:
rebradshaw835
Ex: If the input of the program is:
roster.txt 0 Mcauley
the program outputs an exception message:
Student ID not found for Mcauley
Ex: If the input of the program is:
roster.txt 1 rebradshaw835
the output of the program is:
Reagan
Ex: If the input of the program is:
roster.txt 1 mpreston272
the program outputs an exception message:
Student name not found for mpreston272
NOTE: Please feel free to make content of your file the way you like.
You may use an ArrayList to hold the content of the file. You may change the parameters of your findID or finadName.
Hint. Try first to have a file, read the content and print to see it works first.

- السؤال 1 .Write a program in java to enter length and width to find the area of a rectangle Use exception handling, if a user enters some wrong input, then program should throw an exception and this program should catch the exception example if in place of length or width a user enters some string value .then the program should throw an exception .Use finally keyword to print the statement استعراض الملفات المحلية إرفاق ملفarrow_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_forwardPLZ help with the following IN JAVA If a method throws an exception, and the exception is not caught inside the method, then the method invocation: terminates transfers control to the catch block transfers control to the exception handler none of the abovearrow_forward
- write a propram has a exception class named "Exception" that must inheritfrom the C++ runtime_errorclass.This class will capture the error case for a variable price when it is negative.For example, if the user tries to create with a variable price -1, it will generate an exception and this class should capture the reason and the error value, then print:Error: Invalid price. Ignored.arrow_forwardA throw statement - throw new Exception() - is used to throw an exception. True Falsearrow_forwardin c++ Define a new exception class named "BadValueException" that must inherit from the exception class. It will manage and capture the general invalid integer and double value. It must be able to describe the reason for the error and save away the erroneous value. In another words, when the caller catches the exception and receives this object, it must know what the reason for the exception is and the actual bad value that caused the exception.arrow_forward

- in c++ Write a function named createOneStudent that will read in from the user the student info: id, name and gpa. It will use try-catch to handle the exception if the user provides a negative id or gpa that is out of bound (< 0.0 or > 4.0) by asking the user to re-enter them. It must provide the correct reason for the error and the actual error value. Then it will allow the user to try up to 3 times. This function will return the pointer of a newly created Student object or nullptr if the info is still incorrect. Note that this function can and will use cin and cout to read in values from the user. Here is an example of a run up to 3 times: Enter ID: -1 Enter GPA: 4.0 Enter name: John Smith Exception: negative id: -1 Enter ID: 1234 Enter GPA: 5.0 Enter name: John Smith Exception: out of bound gpa: 5.00 Enter ID: 1234 Enter GPA: 4.0 Enter name: John Smith ID(1234) NAME(John Smith) GPA(4.00) Here is an example of a run of 3 times and still not able to create it: Enter ID: 1234...arrow_forward3-19 Please write a CHECKED EXCEPTION in Java Code per the instructions and make sure your code compiles before submitting.

What happens if an exception is thrown, but not caught? 5. Complete the following function that searches a numeric array for a specified value. The function should return the subscript of the element containing the value if it is found in the array. If the value is not found, the function should throw an exception. int searchArray(int array[], int size, int value){ int index = 0; // Used as an index to search array int subscript = -1; // To record position of search value while (index < size && subscript == -1) { if (array[index] == value) // If the value is found ___________________________________________________ ___________________________________________________ } if (subscript == -1) ___________________________________________________ return subscript; } Bonus...arrow_forward
