Use java. Exercise 4 - Simple Calculator with Exception HandlingCreate a new class called Simplecalc. In this class, implement a program that asks the userto enter an arithmetic expression and then output the result. The program should stop when theuser enters the word "stop".Output should like the following:Enter expression: 3 / -Incorrect input, try again.Enter expression: 4324Incorrect input, try again.Enter expression: 4343 + -124331.0Enter expression: 1 * 22.0Enter expression: stopGoodbye.12-

C++ programming D.S.Malik 14-5 Write a program that prompts the user to enter a person’s date of birth in numeric form such as 8-27-1980. The program then outputs the date of birth in the form: August 27, 1980. Your program must contain at least two exception classes: invalidDay and invalidMonth. If the user enters an invalid value for day, then the program should throw and catch an invalidDay object. Follow similar conventions for the invalid values of month and year. (Note that your program must handle a leap year.)

Which type of exception will be raised during execution? A. An IndexOutOfBoundsException is thrown.B. A NumberFormatException is thrown.C. The first slot of the array is used.D. This is an Error, so the program immediately terminates no matter what.E. The last slot of the array is used.

10.11 LAB: Step counter - exceptions (python please) A pedometer treats walking 2,000 steps as walking 1 mile. Write a steps_to_miles() function that takes the number of steps as a parameter and returns the miles walked. The steps_to_miles() function throws a ValueError object with the message "Exception: Negative step count entered." when the number of steps is negative. Complete the main() program that reads the number of steps from a user, calls the steps_to_miles() function, and outputs the returned value from the steps_to_miles() function. Use a try-except block to catch any ValueError object thrown by the steps_to_miles() function and output the exception message. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print(f'{your_value:.2f}') Ex: If the input of the program is: 5345 the output of the program is: 2.67 Ex: If the input of the program is: -3850 the output of the program is: Exception: Negative step count…
ANSWER IN JAVA Standard Output: Enter·side·length·of·square:Side·length·must·be·greater·than·0.↵ Define the class InvalidSideException, which inherits from the Exception class. Also define a Square class, which has one method variable -- an int describing the side length. The constructor of the Square class should take one argument, an int meant to initialize the side length; however, if the argument is not greater than 0, the constructor should throw an InvalidSideError. The Square class should also have a method getArea(), which returns the area of the square.Create a Driver class with a main method to test your classes. Your program should prompt the user to enter a value for the side length, and then create a Square object with that side length. If the side length is valid, the program should print the area of the square. Otherwise, it should catch the InvalidExceptionError, print "Side length must be greater than 0.", and terminate the program.
Python please: Write a square_root() function that takes a number and returns the square root. The square_root() function throws a ValueError object with the message "Exception: Negative input for square root entered." when the number is negative. Complete the main() program that reads a number from a user, calls the square_root() function, and outputs the returned value from the square_root() function. Use a try-except block to catch any ValueError object thrown by the square_root() function and output the exception message. If the user enters something other than an integer, the program throws a ValueError object with the message "invalid literal for int() with base 10: " and 'user_input'. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f}'.format(your_value)) Example: If the input is 100 the output is 10.00 Example: If the input is -55 the output is Exception: Negative input for square root entered. Example: If…
T/F 5) If an exception occurs in a catch phrase, then the violation class matches. For instance, if the following catch sentence may catch an exception of the type ArithmeticException as it is running, and then another exception of that type can be thrown inside the same catch blockbe prepared to grab (ArithmeticException e) {Wrap up}
Part 2 Use exception handeling Write a program (CoconutCherry that This program should accept multiple numbers as command line arguments and print those numbers out again space separated but for multiples of 3 print “coconut” instead of the number, for multiples of 7 print “cherry” instead of the number, and for the multiples of both 3 and 7 print “coconut-cherry” instead of the number. For numbers smaller than 1, print “invalid”
2. Catching Exceptions Implement Exception handling for the programs you have written in the laboratory exercises as listed below. Note that all data to be used for processing must be input data (data entry from the user). When an invalid data is entered, the program should loop back to data entry until the input becomes valid. Sample Output: run: *******CIRCLE CALCULATOR******* Enter the radius --> a INVALID INPUT! Enter the radius --> ? INVALID INPUT! Enter the radius --> 10 Result: Area:314.0 Diameter:20.0 Circumference:62.800000000000004 BUILD SUCCESSFUL (total time: 20 seconds)
Java Code: -Creates ProgramNode, loops over Parse calls correctly, throws exception if unknown item found -(ParseFunction) Uses MatchAndRemove(), handles any number of parameters, fills in ASTNode correctly -(ParseAction) Uses MatchAndRemove(), handles any number of parameters, fills in ASTNode correctly Make sure to give the correct code for parser.java with the screenshots of the output. There must be test cases involved, so make sure to have test cases as well.
Solve the problem in C++ (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".
Modify the MilTime class given under Final exam module. The class should implement the following exceptions: BadHour Throw when an invalid hour (< 0 or > 2359) is passed to the class. BadSeconds Throw when an invalid number of seconds (<0 or > 59) is passed to the class. Demonstrate the class in a driver program. Demo in the main function. the file: // MillTIme.cpp//#include "stdafx.h"#include <iostream>using namespace std;class Time{protected: int hour; int min; int sec;public: Time(int h, int m, int s) { hour = h; min = m; sec = s; } int getHour() { return hour; } int getMin() { return min; } int getSec() { return sec; }}; class MilTime : public Time{private: int milHours; int milSeconds;public: MilTime(int h = 0, int s = 0) : Time(0, 0, s) { if (h < 0 || h > 2359) { cout << "Hours must be in the range 0 - 2359.\n"; milHours = h;…
