Exception - Java Write a program that will compute the factorial of a number. Your program must catch an exception if the input is not a number. For example: Input Result 5 120 w InputMismatchException -5 Invalid Input
. The TryParse methods throw an exception if the string argument cannot be converted
The return Or the throw function sometimes returns a random number and throws anither number as an exception. Write a code that will print out the number that the returnorthrow function gives back even if it throws an exception.
The while loop reads values from input until an integer is read. Complete the exception handler in the while loop to catch an InputMismatchException exception and: Output "Removed unacceptable input for number of cents". End with a newline. Discard the invalid input. Ex: If the input is 20 60, then the output is: 20 cents = 4 nickels Processed one valid input value Ex: If the input is Aya Tia 20 60, then the output is: New JAVA code can only be added after code given: Removed unacceptable input for number of cents Removed unacceptable input for number of cents 20 cents = 4 nickels Processed one valid input value Note: Each value read from input is on one line. /******************************************************************************************************* New Java Code here: test input: Aya Tia 20 60 *******************************************************************************************************/
Time Converter 1. Write a program that converts dates from a numerical month-day format to alphabetic month-day format. IE 1/31 or 01/31 would have an output of January 31. 1. User enters the month and day as a single string. It is then converted. (10%) 2. Create 2 exception classes (20%) 1. MonthException thrown for invalid months 2. DayException-thrown for invalid days for the given month 3. You can assume Feb is always 28 days 2. This should run in a for loop and end when a user is done entering dates (70%)
python Write a program that calculates an adult's fat-burning heart rate, which is 70% of 220 minus the person's age. Complete fat_burning_heart_rate() to calculate the fat burning heart rate. The adult's age must be between the ages of 18 and 75 inclusive. If the age entered is not in this range, raise a ValueError exception in get_age() with the message "Invalid age." Handle the exception in __main__ and print the ValueError message along with "Could not calculate heart rate info." Ex: If the input is: 35 the output is: Fat burning heart rate for a 35 year-old: 129.5 bpm If the input is: 17 the output is: Invalid age. Could not calculate heart rate info. # here is the script I have but its not working def get_age():age = int(input())age=int(input("Enter the age:"))if age<18 or age>75:raise ValueError('Invalid age.')return age # TODO: Complete fat_burning_heart_rate() functiondef fat_burning_heart_rate(age):heart_rate=(220-age)*.70return heart_rate if __name__ == "__main__":#…
s and throws an exception if the second input on a line is a string rather than an int. At FIXME in the code, add a try/catch statement to catch ios_base::failure, 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 34 419894.2696446.qx3zqy7 #include <string>#include <iostream> using namespace std; int main() { string inputName; int age; // Set exception mask for cin stream cin.exceptions(ios::failbit); cin >> inputName; while(inputName != "-1") { // FIXME: The following line will throw an ios_base::failure. // Insert a try/catch statement to catch the exception. // Clear cin's failbit to put cin in a useable state. cin >> age; cout << inputName << " " << (age + 1) << endl; cin >> inputName; } return 0;}
Challenge 2: InvalidNumbers.java Write a program InvalidNumbers that asks the user to enter a positive integer. The program will warn the user if a valid integer is not entered using the InputMismatchException and ask to enter again. The program should also throw an exception if the user enters negative numbers. Write the program and test it using negative numbers, doubles, and very large numbers.
When an exception occurs it is said to have been thrown. handled. O caught. O resolved.

Java Exception method withdraw throws an exception if amount is greater than balance. For example: Test Result Account account = new Account("Acct-001","Juan dela Cruz", 5000.0); account.withdraw(5500.0); System.out.println("Balance: "+account.getBalance()); Insufficient: Insufficient funds. Balance: 5000.0 Account account = new Account("Acct-001","Juan dela Cruz", 5000.0); account.withdraw(500.0); System.out.println("Balance: "+account.getBalance()); Balance: 4500.0
c++ programming Lab 10-1: Write a test program to accept two numbers from consol. Then check to see if first number is larger than second number . If it is throwing an exception and handle the error properly. Lab 10-2: Write a test program to accept a number from consol. then check to see if the number is positive or negative. If it is negative throw an exception and indicate the number is negative otherwise take the squire root of the number. Use exception handling to control the flow of the code. Lab 10-3: Write a test program to accept a number from consol. This number is radius of circle if the number is positive find area and circumference. Otherwise, throw an exception with proper message. Lab 10-4: Show the output of the following code with input 10, 60, and 120, respectively.
