- T/F 4) Custom-defined exceptions may be defined by expanding either of the Exemption class or one of its subclasses.Python help Each of the following will cause an exception (an error). Identify what type of exception each will cause. Trying to add incompatible variables, as in adding 6 + ‘a’ Referring to the 12th item of a list that has only 10 items Using a value that is out of range for a function’s input, such as calling math.sqrt(-1.0) Using an undeclared variable, such as print(x) when x has not been defined Trying to open a file that does not exist, such as mistyping the file name or looking in the wrong directory.Calculator.java, is a simple command-line calculator. Note the program terminates if any operand is nonnumeric.Write a program with an exception handler that deals with nonnumeric operands;then write another program without using an exception handler to achieve thesame objective. Your program should display a message that informs the user ofthe wrong operand type before exiting
- 2.14 LAB: Exception handling to detect input string vs. integer The given program reads a list of single-word first names and ages (ending with -1), and outputs that list with the age incremented. The program fails and throws an exception if the second input on a line is a string rather than an integer. At FIXME in the code, add try and except blocks to catch the ValueError exception and output 0 for the age. Ex: If the input is: Lee 18 Lua 21 Mary Beth 19 Stu 33 -1 then the output is: Lee 19 Lua 22 Mary 0 Stu 34JAVA EXCEPTION HANDLING Complete the java code below according to the instructions given. Also use the test example below: Define the exceptions that are necessary to catch the possible errors that can occur in the class Matrix • ExceptionWrongMatrixValues that is thrown in the method read() if the data on the String does not correspond to numeric values, or if the data are not consistent with the form of a matrix (e.g., the rows have different length); • ExceptionWrongMatrixDimension that is thrown in the method read() if the data on the String do not correspond to the dimension of the matrix. The numbers are separated by space. A dot in a string means the next string of text is for the next row. For example: Test Result String input="1 2 3 . 1 e 3 ."; Matrix m = new Matrix(); m.read(input); ExceptionWrongMatrixValues String input="1 2 3 . 1 2 3 4 5 ."; Matrix m = new Matrix(); m.read(input); ExceptionWrongMatrixValues String input="12312345"; Matrix m = new Matrix();…Please give the names of the various approaches of managing exceptions that are available.
- DIRECTION: Using Java as program language Create a simple program for a quiz bee with a class named QuizBee. The program shall:o Contain an array of 15 multiple choice questions with three (3) choiceseach and;o Require the user to choose among A, B or C.o Note: Cases are ignored. Lowercase letters are acceptable (a,b, or c) Create a try-catch structure to handle three (3) exceptions. These are when theuser inputs the following:o An invalid letter (not A, B or C)o A number or any special character.o Blank (no answer). Prompt the user to answer again if any of the three (3) exceptions is thrown. Display the score, number of incorrect answers and corrects answers.C++ 1: Define a class named “Variable” that manages a variable name (string) and a description (string). It should not provide the default constructor. And the “VariableString” class that must inherit from the "Variable" class. This class manages a variable name (string), description (string), and value (string). Define a new exception class “VarNameException” that must inherit from the C++ runtime_error class. This class will capture the error case (generate an exception and capture reason and error value) for a variable name when it does not start with a letter (lower case or upper case) or contains at least one blank (for instance: "9name", "*name" or "first name"). The class named “Variable” should generate a "VarNameException" whenever the caller tries to create the Variable object with a bad name. 2: Write a function “createVariableObject” that will read the variable name, description, and a value (string) from the user and create a dynamic Variable or VariableString depending…4.10 LAB: Exception handling to detect input string vs. integer The given program reads a list of single-word first names and ages (ending with -1), and outputs that list with the age incremented.

- The problem comes from Introduction to C++ Programming and Data Structures, 4th Edition (HexFormatException)Implement the hex2Dec function in Programming Exercise 16.1 to throw a HexFormatException if the string is not a hex string .Define a custom exception class named HexFormatException. Write a test program that prompts the user to enter a hex number as a string and displays the number in decimal. If the function throws an exception, display "Not a hex number".Task 4: User Defined Exceptions (Java) A school is enrolling contestants for a competition for students of age 15 and above. Write a Java application to read the ID and age of a student. If the ID does not start with the characters ST or if the age is less than 15, throw a user defined exception InvalidStudentException and display the message “The student is not eligible!!”. If the details entered are valid, display the message “The student is eligible”. Sample Test case: Enter Student ID: ST1500 Enter Age: 14 The student is not eligible!!Explain Rethrow (propagate) exception with help of code.
