int x = 1234567890; String s = Integer.toString(x); System.out.print(s.length()==10?true:false); //so we get some ints //we then convert int to string using toString method thats inside class Integer //as string is an object it has methods so we access one of its methods called length //we then check to see if the returned value equals 10 if yes print true else print false

String input = "6282526282"; int pos = 2; System.out.print(Integer.valueOf(input.charAt(pos)+"")*pos); /* so this would be starting from index 0 8*2 = 16 */
