Java > Warmup-1 > front22 (CodingBat Solution)

Problem:

Given a string, take the first 2 chars and return the string with the 2 chars added at both the front and back, so "kitten" yields"kikittenki". If the string length is less than 2, use whatever chars are there.

front22("kitten") → "kikittenki"
front22("Ha") → "HaHaHa"
front22("abc") → "ababcab"

Solution:

public String front22(String str) {
  if (str.length() > 2) {
    String temp = str.substring(0,2);
    return temp + str + temp;
  } else
    return str + str + str;
}
