Task $1$: TemperatureConverter $[25$ PTS$]$

Create a class named TemperatureConverter. In this class, define two methods:

celsiusToFahrenheit$($double celsius$)$: This method takes a temperature in Celsius as input and returns the equivalent value in Fahrenheit. Use the formula Fahrenheit $=($Celsius $*9/5)+32.$

fahrenheitToCelsius$($double fahrenheit$)$: This method takes a temperature in Fahrenheit as input and returns the equivalent value in Celsius. Use the formula Celsius $=($Fahrenheit $-32)*5/9.$

Implement exception handling in both methods:

Throw a custom exception named TemperatureBelowAbsoluteZeroException if the input temperature is below absolute zero $($Celsius: below $-273\mathrm{.}15$C$,$ Fahrenheit: below $-459\mathrm{.}67$F$)$

Task $2$: TemperatureBelowAbsoluteZeroException $[10$ PTS$]$

Create a custom exception class named TemperatureBelowAbsoluteZeroException that extends the RuntimeException class. This exception represents the scenario where the user enters a temperature below absolute zero.

Task $3$: Demo $[25$ PTS$]$

Create a Demo class and in your main method, prompt the user to enter the temperature $($Celsius or Fahrenheit$)$ and the desired conversion $($C to F or F to C$)$:

Use a loop to allow repeated conversions until the user exits.

Read user input using Scanner.

Use a try$-$catch block to handle potential exceptions:

Inside the try block, call the appropriate conversion method $($celsiusToFahrenheit or fahrenheitToCelsius$)$ based on the user's selection.

In the catch block $($catching TemperatureBelowAbsoluteZeroException$),$ display an appropriate error message to the user and prompt them to enter a valid temperature.
