double per=0.0;
while(i<args.length)
{
name = args[i];
hindi=Integer.parseInt(args[i+1]);
english=Integer.parseInt(args[i+2]);
maths=Integer.parseInt(args[i+3]);
sst=Integer.parseInt(args[i+4]);
science=Integer.parseInt(args[i+5]);
tot=hindi+english+maths+sst+science;
per=(tot*100/500);
i=i+6;
if(per>=60)
div="First";
else if(per<60 && per>=50)
div="Second";
else if(per<50 && per>=40)
div="Third";
else
div="Fail";
System.out.println(" Student Name:"+name);
System.out.println("| Hindi | English | Maths | SSt | Science | Total | Per | Div |");
System.out.println("| "+hindi+" | "+english+" | "+maths+" | "+sst+" | "+science+" | "+tot+" |"+per+" |"+div+" |");
System.out.println("-----------------------------------------------------------------------------------------------");
}
}
}
