JAVA PACKAGES PROGRAMS

We have to create 3 different packages for this program  and execute  it.

Vehicle.java

package package1;

public abstract class Vehicle
{    
            public int year;
            public abstract void getData();
            public abstract void putData();
}

class FourWheeler extends Vehicle{
            public void getData()
            {
                  year=92;
            }
            public void putData()
            {
                  System.out.println("Year of manufacture of the fourwheeler is"+year);
            }
}
 

prog2.java

package package2;
import package1.*;
class TwoWheeler extends Vehicle{
      private String EngineType="2-s";
      protected String Brand="Y";
      public String Color="Black";
      public void getData()
      {
                  EngineType="2-stroke";
                  Brand="Yamaha";
                  Color="Black";
                  year=88;
      }
      public void putData()
      {
                  System.out.println("Year of manufacture of the twowheeler is"+year);
                  System.out.println("Engine type is " +EngineType+" ,Brand is "+Brand+" ,Color is "+Color);
      }
            void printprivate()
      {
                  System.out.println("Accessing private variable"+ EngineType);
      }
      }
class MyTwoWheeler extends TwoWheeler
{
      public String OwnerName;
      MyTwoWheeler()
      {
            super();
            OwnerName="Mandhara";
            printprivate();
            System.out.println(""+Brand+" "+Color+" "+OwnerName);
      }
     
}

public class prog2 {
      public static void main(String[] args)
      {
            TwoWheeler a=new TwoWheeler();
            a.getData();
            a.putData();
            MyTwoWheeler b=new MyTwoWheeler();
      }

}
 

prog.java

package package3;

public class prog {

}
