Isolating Digits using charAt or some other method.
807603Feb 12 2008 — edited Feb 13 2008When i ask the user to enter a 9 digit sin number ie: "936 564 856" i want my program to A) eliminate spaces to make one big number / integer and B) Apply a algorhithm.
I have got my program to eliminate the spaces by doing this:
String input;
String inputNoSpaces = "";
for( int i = 0; i < input.length(); i++ ){
if ( input.charAt(i) != ' ' ){
inputNoSpaces = inputNoSpaces + input.charAt(i);
}
}
Now i want to apply my algorhithm to every second digits starting from the right so "5,4,5,3" and leave the other ones alone. I was thinking of isolating every second digit using charAt commands or something.
How will i go about doing this - that is isolating every second digit so i can apply my algorhithm.
