Problem $2.$

Define a class named Airport that has the following

$-$ An instance variable named name of type String

$-$ An instance variable named capacity of type int

$-$ An instance variable named rank of type int

$-$ A constructor that takes no argument and sets name to $"$SkyFly$",$ capacity to $3,$ and rank to $1.$ The constructor's header is

Airport$()$

$-$ A constructor that takes three parameters and sets the instance variables accordingly. The constructor's header is

Airport$($String newName, String newCapacity, double newRank$)$

$-$ An instance method that displays the instance variables of the invoking object in a format of your choice. The method's header is void displayAirport$()$
