public static void main(String[] args){

 int a,b,c,d;

 double average=0.0;

 Scanner s=new Scanner(System.in);

 System.out.println("Enter first number: ");

 a=s.nextInt();

 System.out.println("Enter second number: ");

 b=s.nextInt();

 System.out.println("Enter third number: ");

 c=s.nextInt();

 System.out.println("Enter fourth number: ");

 d=s.nextInt();

 average=(a+b+c+d)/4.0;

 System.out.println("Average: "+average);

}

}
