Java > Warmup-1 > notString (CodingBat Solution)


Given a string, return a new string where "not " has been added to the front. However, if the string already begins with "not", return the string unchanged. Note: use .equals() to compare 2 strings.

notString("candy") → "not candy"
notString("x") → "not x"
notString("not bad") → "not bad"


public String notString(String str) {
  if (str.startsWith("not"))
    return str;
    return "not " + str;
