input is not command line…it is using stdin…use Scanner or BufferedReader!!!

You are not taking any input in your solution. Input on codechef is not by command line parameters but by using the standard input. So for standard input in java you should use BufferedReader or Scanner(though Scanner is very slow).

   Scanner sc=new Scanner(System.in);
   int[] a=new int[5];
   //System.out.println("enter elements");
    for(int i=0;i<a.length;i++){
    a[i]=sc.nextInt();
    }
    for(int i=0;i<a.length;i++)
    {
        if(a[i]==42)
        break;
