Consider the following class:

public class FlightInstruction {

 /* Responsible for holding a flight instruction

 * for a autonomous quadcopter.

 *

 * Instructions will be queued after creation for execution.

 * After execution, they should be placed in a hashtable for

 * easy retrieval of flight logs.

 *

 * Don't worry about the size of the hashtable. */

 String instructionID;

 float roll;

 float pitch;

 float yaw;

 float throttle;

 public FlightInstruction(String instructionID, float roll, float pitch, float yaw, float throttle) {

 this.instructionID = instructionID;

 this.roll = roll;

 this.pitch = pitch;

 this.raw = yaw;

 this.throttle = throttle;

 }

 /** ..Getters and Setters.. **/

 @Override

 public int hashCode() {

 // Implement me!

 }

}

Implement the hashcode method for this class.
