$(10$ points$)$ Write a class called CelToFah where a user inputs a Celsius degree in double type from

the console, then converts it to Fahrenheit and displays the results. Formula for the conversion is:

fahrenheit $=(\frac{9}{5})**$ celsius $+32$

Tips

For Java, $9/5$ is $1,$ so you need to write $9\mathrm{.}0/5$ in the program to obtain the correct result.

In order to take keyboard input from the console, use the Scanner class.

Sample Run

Problems

$20\mathrm{.}5$ Celsius is $68\mathrm{.}9$ Fahrenheit

Submission

Copy and paste your code.

$,$ Screen shot the console with user input of $90\mathrm{.}3$

Screen shot the console with user input of $163\mathrm{.}7$

Screen shot the console with user input of Apple $($error should occur$)$
