You need to swallow up the ENTER that you push after inputting your numeric value.

e.g.

int rockSize=sc.nextInt();
sc.nextLine();                         // add this
String[] rock=new String[rockSize];
for(int i=0;i<rock.length;i++)
rock[i]=sc.nextLine();

thank you , but why we need to put this extra line? can u plz explain? – Marees waran Dec 08 '15 at 07:17
@Mareeswaran - because `nextInt()` leaves behind a new-line character (when you press "enter"). `nextLine()` consumes it – TheLostMind Dec 08 '15 at 07:18
