it is not compiling

Question

import java.util.*;
class racdemo
{
  public static void main(String args[])
  {
    Float n1,n2,n3,n4,n5,avg;
  Scanner s=new Scanner(System.in);
    n1=s.nextFloat();
    System.out.println("eneter the first racer");
    n2=s.nextFloat();
   System.out.println("enter the second racer");
    n3=s.nextFloat();
    System.out.println("enyter the third racer");
    n4=s.nextFloat();
    System.out.println("enter the fourth racer");
    n5=s.nextFloat();
    System.out.println("enter the fifth racer");
    avg=n1+n2+n3+n4+n5/5;
    System.out.println("averaage"+avg);
    if(n1>avg)
      System.out.println("1st racer winner");
    else if(n2>avg)
      System.out.println("2nd racer winner");
    else if(n3>avg)
      System.out.println("3rd racer winner");
    else if(n4>avg)
      System.out.println("4th racer winner");
    else if(n5>avg)
      System.out.println("5th racer winner");
  }
}

Answer 1

import java.util.*;

class Main // Not class racdemo
{
    public static void main(String args[])
    {   
        //Your code as usual..
    }
}

Looks like Online compiler only works with class Main.

Answer 2

import java.util.Scanner;
class racdemo
{
  public static void main(String args[])
  {
    Float n1,n2,n3,n4,n5,avg;
  Scanner s=new Scanner(System.in);
    n1=s.nextFloat();
    System.out.println("eneter the first racer");
    n2=s.nextFloat();
   System.out.println("enter the second racer");
    n3=s.nextFloat();
    System.out.println("enyter the third racer");
    n4=s.nextFloat();
    System.out.println("enter the fourth racer");
    n5=s.nextFloat();
    System.out.println("enter the fifth racer");
    avg=n1+n2+n3+n4+n5/5;
    System.out.println("averaage"+avg);
    if(n1>avg)
      System.out.println("1st racer winner");
    else if(n2>avg)
      System.out.println("2nd racer winner");
    else if(n3>avg)
      System.out.println("3rd racer winner");
    else if(n4>avg)
      System.out.println("4th racer winner");
    else if(n5>avg)
      System.out.println("5th racer winner");
  }
}

Answer 3

import java.util.*;

class Racdemo

{

static float n1,n2,n3,n4,n5,avg;

  public static void main(String args[])

  {

  Scanner s=new Scanner(System.in);

    n1= s.nextFloat();

    System.out.println("eneter the first racer");

    n2=s.nextFloat();

   System.out.println("enter the second racer");

    n3=s.nextFloat();

    System.out.println("enyter the third racer");

    n4=s.nextFloat();

    System.out.println("enter the fourth racer");

    n5=s.nextFloat();

    System.out.println("enter the fifth racer");

    avg=(n1+n2+n3+n4+n5)/5;

    System.out.println("averaage"+avg);

    if(n1>avg)

      System.out.println("1st racer winner");

    else if(n2>avg)

      System.out.println("2nd racer winner");

    else if(n3>avg)

      System.out.println("3rd racer winner");

    else if(n4>avg)

      System.out.println("4th racer winner");

    else if(n5>avg)

      System.out.println("5th racer winner");

  }
