Question

I’m trying to figure out how I could use a java program to return the last 3 digits of an integer.

So for example if I had a number like 45678 how would I be able to return 678? Also how would I be able to determine that the length of this integer is 5 digits?

Answer 1

String s = Integer.toString(45678);
s.substring(s.length() - 3); // first answer
s.length() == 5; // second answer
