IntArray Class Exception
Chapter 14 presented an IntArray class that dynamically creates an array of integers and performs bounds checking on the array. If an invalid subscript is used with the class, it displays an error message and aborts the

- Challenge 1: Division.java You have to implement a Division class that divides two numbers given by the user. The program should handle exceptions that could be thrown during operation: If the second number is 0 If any of the numbers is not a valid number, such as a letter.arrow_forward(Stack Unwinding) Write a program that throws an exception from a deeply nested function and still has the catch handler following the try block enclosing the initial call in main catchthe exception.arrow_forwardWrite a class named TestScores. The class have an integer array to store test scores, provide getters, setters, constructor should accept an array of test scores as its argument. The class should have a member function that returns the average of the test scores. If any test score in the array is negative or greater than 100, the class should throw an exception. Also if number of values increases the array size it should throw an exception, Demonstrate the class in a program. Use exceptions Programming language : Javaarrow_forward

The class should have two constructors, one of which should be the default function Object() { [native code] }. If the default function Object() { [native code] } throws an error, the function should return "Tornado: Take cover immediately!" The other function Object() { [native code] } takes a single int argument, say m. If this function Object() { [native code] } throws an error, the function should return "Tornado: m miles distant; and approaching!"arrow_forwardC++ The People class holds an unsorted list of humans. Initially, this list is empty. Upon inserting a Human object, it is added to the array at the next available position and the position value in incremented. If the position value is equal to the size value, do not insert the Human. Instead, throw an exception that your driver can catch to print an error that the People object is full. Create a People class with the following features: Each People object has a statically allocated array of Human objects. Size attribute representing the maximum size of the array. Position attribute representing the next free position in the array. Default constructor with no arguments. Search method that takes a string argument and returns a Human object. This method returns the first Human object with a name matching the string argument. In other words, pass the name of a Human as a string, search the list of humans for one with that name. If found, return this human. Else throw an…arrow_forward
- 1. Exceptions Quiz by CodeChum Admin Write a program that accepts an integer N which serves as the size of an array. Ask for N number of elements. After, continuously ask for user input index. Mark the element at that index as zero. If the user gives an invalid index, throw the appropriate exception and print "Illegal index!". The program ends once an exception is thrown or once the array contains only zeroes. Lastly, print the array elements separated by space. Inputs 1.

The class have an integer array to store test scores, provide getters, setters, constructor should accept an array of test scores as its argument. The class should have a member function that returns the average of the test scores. If any test score in the array is negative or greater than 100, the class should throw an exception. Also if number of values increases the array size it should throw an exception, Demonstrate the class in a program. Programming language : Javaarrow_forward1- The FloatArray class stores a dynamic array of floats and its size. It has:- A parameterized constructor that takes the array size. - An add method that adds a float at the end of the array.- Overloading for the insertion operator << to write the array to afile (ofstream)- Overloading for the extraction operator >> to read the array elements from the file (ifstream) and add them to the array.- A destructor to deallocate the array2- The SortedArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size. - An add method that adds a float at the right place in the arraysuch that the array remains sorted with every add. Don’t add to the array then sort but rather add in the right place.3- The FrontArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size. - An add method that adds a float at the front of the array.4- The PositiveArray that inherits from SortedArray. It has:- A parameterized constructor…arrow_forward
- Add preconditions to the methods __getitem__ and __setitem__. The precondition of each method is 0 <= index < size(). Be sure to raise an IndexError exception if the precondition is not satisfied. To test your program run the main() method in the arrays.py file. Your program's output should look like the following: Physical size: 10 Logical size: 0 Items: [None, None, None, None, None, None, None, None, None, None] Traceback (most recent call last): File ".solution/arrays.py", line 69, in <module> main() File ".solution/arrays.py", line 66, in main print(a[0]) File ".solution/arrays.py", line 45, in __getitem__ raise IndexError("Array index out of bounds") IndexError: Array index out of boundsarrow_forwardQ1 (Creating Custom Exception Class) Write a Password class that stores a password string. Passwords must contain at least seven alpha-numeric characters, with at least one letter and one digit. Also write an InvalidPasswordException class that extends Exception. The Password constructor should throw an InvalidPasswordException, which should report an appropriate message based on a given string (e.g. if the string contains no digits, the exception should report this fact). Write a GUI program to prompt the user to enter a password and report an InvalidPasswordException if an invalid password is entered. Please teach and help me how to deisgn the program based on the two files given .Some sample screenshots are shown below: InvalidPasswordException.java public class InvalidPasswordException extends Exception{ public InvalidPasswordException (String errMsg){ super(errMsg); } } Password.java public class Password {private String passwordstr; public…arrow_forwardCLASSES, DYNAMIC ARRAYS AND POINTERS Define a class called textLines that will be used to store a list of lines of text (each line can be specified as a string). Use a dynamic array to store the list. In addition, you should have a private data member that specifies the length of the list. Create a constructor that takes a file name as parameter, and fills up the list with lines from the file. Make sure that you set the dynamic array to expand large enough to hold all the lines from the file. Also, create a constructor that takes an integer parameter that sets the size of an empty list. in C++ Write member functions to: remove and return the last line from the list add a new line onto the end of the list, if there is room for it, otherwise print a message and expand the array empty the entire list return the number of lines still on the list take two lists and return one combined list (with no duplicates) copy constructor to support deep copying remember the destructor!arrow_forward
