Question

create a class in Java for a Plane

the class will include

String Data Fields for the make, model, and year. (as well as mutators and accessors)

Defined constructor and copy constructor.

there must be a toString method as well as a copy method.

runner program

the program will create an array for Plane class. The size of the array will be set to user input. then the user will input the information into each plane object in the array. Asking the user to enter the make, model, and year. then it will output all the planes using the tostring method

Answer 1

1.Plane Class

public class Plane {
   String make, model,year;

   public String getMake() {
       return make;
   }

   public void setMake(String make) {
       this.make = make;
   }

   public String getModel() {
       return model;
   }

   public void setModel(String model) {
       this.model = model;
   }

   public String getYear() {
       return year;
   }

   public void setYear(String year) {
       this.year = year;
   }

   // Constructor
   public Plane(String make, String model,
   String year)
   {
   this.make = make;
   this.model = model;
   this.year = year;
   }

   // Used to print Plane details in main()
     
   public String toString()
   {
   return "Make of Plane:"+ this.make + "Model:" + this.model + " Year:" + this.year;
   }

}

2.Main Plane Class

import java.util.Scanner;
public class PlaneMain {

   public static void main(String[] args)
   {
      
   // asking the user how many they would like to add
       int choice;
       Plane[] StArray;
       Plane p = new Plane(null, null, null);
   System.out.print("How many new Planes are you going to add: ");
   Scanner in = new Scanner(System.in);
   choice = Integer.parseInt(in.nextLine());
      
       //creating Plane array of chosen amount
   StArray = new Plane[choice];
  
       //asking user for the variables and trying to display them?
       for (int x = 1; x < StArray.length; x++)
       {
   System.out.print("Enter the Make of plane " + ": ");
   p.make = in.next();
   System.out.print("Enter the Model of plane " +": ");
   p.model = in.next();
   System.out.print("Enter the Year of plane " +": ");
   p.year = in.next();
   System.out.println(p.toString());

       }
}
