//Main Class
class Main
{
//Main method
public static void main(String[] args) throws Exception
{
//A variable is declared and a data is assigned
String status = "bad";

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_heartrate() 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.
How can you display the default error message when an exception is thrown?

- How can the default error message be shown whenever an exception is thrown?arrow_forwardA thrown exception may contain more information about what caused the exception. True or Falsearrow_forwardc++ 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.arrow_forward
- use C++ programing language 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. Similar conventions for the invalid values of month and year. (Note that your program must handle a leap year.)arrow_forwardDefine an exception class called CoreBreachException. The class should have a default constructor. If an exception is thrown using zero-argument constructor, getMessage should return "Cor Breach Evacuation Ship!" The class should also define a constructor having a single parameter of type String. If an exception is thrown using constructor, getMessage should return the value that was used as an argument to constructor.arrow_forwardA custom exception type is usually defined by: inheriting from the exception class.
