Explanation on this code JAVA

Scanner s=new Scanner(System.in); char size; int topping; double price=0.00; System.out.println("Enter the Pizza Size(S,M,L):- "); size=s.next().charAt(0); System.out.println("Enter the no. of toppings:- "); topping=s.nextInt(); if(Character.compare(size, 'S')==0) price+=8.50; else if(Character.compare(size, 'M')==0) price+=10.50; else if(Character.compare(size, 'L')==0) price+=12.50; price+=(topping-1)*0.50; price+=(price*0.07); System.out.println("Your Pizza Cost is:- $"+price); } }

can someone put comments to tell what each line does ?
