- 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.arrow_forwardWrite the code in java and please don't plagiarize or copy from other sources write it on your own.

- 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.

- 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 34arrow_forwardDesign and implement a program that creates an exception classcalled StringTooLongException, designed to be thrown when astring is discovered that has too many characters in it. In the maindriver of the program, read strings from the user until the userenters "DONE". If a string that has too many characters (say 20) isentered, throw the exception. Allow the thrown exception toterminate the programarrow_forwardAgain --4. 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.
