}
}
class TwoWheeler extends Vehicle
{

void maintenance()
{
int m=p+1500;
System.out.println("the total maintainance of twowheeler is"+m);
}
void average(int x,int y)
{
float m;
m=y/x;
System.out.println("the average of two wheeler is"+m);
}
}
class FourWheeler extends Vehicle

System.out.println("the total maintainance of Fourwheeler is"+m);
}
void average(int x,int y)
{
float m;
m=y/x;
System.out.println("the average of 4 wheeler is"+m);
}
}
class Automobile
{
public static void main(String args[])
{
System.out.println("Enter your petrol consumption");
Scanner s1=new Scanner(System.in);
int x=s1.nextInt();
System.out.println("Enter your total km run");
int y=s1.nextInt();
Vehicle v=new Vehicle();
TwoWheeler v1=new TwoWheeler();
 v1.vno=923;
v1.insno=1012;

2. Programe for Area of Circle in java ?

1. class Area
2. {
3.  public static void main(String []args)
4.  {
5.   double r=10,c;
6.   System.out.println("The Radius of circle r = "+r);
7.   c=3.14*r*r;
8.   System.out.println("The area of circle is = "+c);
9.   }
10. }

//output is.....

3. Programme of avarge in java ?

import java.util.Scanner;

class Average

{

 public static void main(String []args)

 {

  Scanner s=new Scanner(System.in);

  double a,b,c,d,avrg;

  System.out.println("Enter 4 number to Average ");

  a=s.nextDouble();

  b=s.nextDouble();

  c=s.nextDouble();

  d=s.nextDouble();

  avrg=(a+b+c+d)/4;

  System.out.println("The average is = "+avrg);

  }

}

//output is.....
