Design a class representing a mobile phone. Make sure the class contains the following:

An attribute representing the mobile phone's International Mobile Equipment Identity number $($format: $15$ decimal digits for our purposes$).$ Make this a of type String.

An attribute representing whether the mobile phone is on$/$off$.$ Make this of type boolean.

A constructor taking a String IMEI number.

An operation to make a call. This should take a String parameter indicating the number to call. This method has some logic and three cases to handle:

If the phone is not powered on$,$ just print a message indicating that condition.

If the phone is powered on and the number is the special number $"*$#$06$#$",$ then print the IMEI number.

Otherwise, print a message indicating that a call is initiated to the "number to call". See test data below for message examples.

An operation to power on the phone. This should turn the mobile phone on$.$

Getters where appropriate.
