- Calculator.java, is a simple command line calculator.Note that 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 the same objective. Your program should display a message that informs the user of the wrong operand type before exiting. (See Figure 1)your code does not run Exception Handling correctly like shown in my 2nd picture . Can you please fix it ?JAVA CODE Unchecked exceptions are exceptions that are usually the result of a mistake and we aren't expected to handle, while checked exceptions are exceptions that we reasonably expect to occur that we should handle whenever possible. Name one type of unchecked exception and one type of checked exception, and give an example of situations that might cause those exceptions to be thrown.
- Please written by computer source Implement try/except exception handler to catch all errors (from the following source code) separately: my_string = 'Hello World' print(my_string) num = int(my_string) print(my_string + 100) num = 1/0 print(total) print('Done') Submission Instructions: 1. Write all the code in one module (in one .py file), and save it as Firstname_Lastname_hw6.py (e.g., John Adam’s file name should be John_ Adam_hw6.py).Design and implement a program that reads an integer value (let's say x) as a command line argument. Further, the program reads a series of 'x' integer values from the user and prints their average. Read each input value as a String, and then attempt to convert it to an integer. If this process throws an exception (meaning that the input is not a valid number), print the appropriate error message and prompt for the number again. Continue reading values until 'x' valid integers have been entered. Hint: Think of all possible errors that this process could cause, and incorporate appropriate exception handlers in your programs. Note: You cannot use the root/general exception class 'Exception'List three exception types from the java.io package.
- Write a shell script that prompts the user to guess a number between 1 and 64 with hints, if the number guessed is too high or to low if the user can guess the correct number in 6 attempts or less, the user wins. Otherwise, the user loses. Make sure to do the proper exception handling in your code.Assignment: - Ramesh is software engineer in a organization. He is really a good coder but by mistake he got an error while working in a Apex Class. Where he get a SOQL Limit exhausted (SOQL 101 Exception). Please Help what he do to handle the error. SOQL, Saleforce, ApexWrite a java program called AddressBook which allows the user to enter names, phone Numbers and email address and saves them into a text file called addresses.txt. Then have the user enter the last name and have the program read back that person's contact info. Exception handling should be used to display an error message if the program is unable to open the file or the person being searched for does not exist. You may use the code examples on pages 622-623 for a similar example to how your program should be written. For example: Welcome to Address Book! Enter last name, first name, phone number, and email address Enter EOF to end input Doe John 555-123-4567 jdoe@gmail.com Stevens John 845-688-6017 stevensj@gmail.edu > EOF Enter last name to search: Doe Record Found: John Doe 555-123-4567
- I need a Java program that utilizes a user-defined exception named LowBalanceException. The program can be simple but I want the exception to be thrown if their account balance goes below a minimum threshold such as $50. Please and thank you kind strangerArman has a shop where he provides stuff on rent. The whole payment system is computerised. A customer has to enter the item name, item type, cost, and the number of days they have taken the item for rent. The system then tells them the cost per day. But there is a problem with the machine that if the number of days entered is not an integer value then the system would crash. To handle this, Arman decided to upgrade the software and use exception handling in case the customer entered any invalid input it should display " Number of days x is invalid". Write a C++ program to find the item cost per day with the cost for n days given. The arithmetic exception has to be thrown if the n is less than or equal to zero. Strictly adhere to the Object-Oriented specifications given in the problem statement. All class names, member variable names, and function names should be the same as specified in the problem statement. The class Item has the following private data members. Data typeVariable…Java displays an exception message when the program code could have prevented an error. Using scanner. create an exception handling method that declares three integers, prompts the user for values for two of them, and calculate the value of third integer by diving the first two values.
