The BusinessPlane class extends Airplane. It has one additional instance variable, boolean isJet, that is true if the plane has jet engines and is false

The BusinessPlane class extends Airplane. It has one additional instance variable, boolean isJet, that is true if the plane has jet engines and is false if it has some other form of propulsion. Since most BusinessPlane objects have jet engines, it is not necessary to input the initial value of the isJet instance variable in the constructor. Instead, the instance variable is given an initial value of true. But a modifier method is provided to change the value if necessary. Complete the following definition for the BusinessPlane class:
