Problem:
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"
Solution:
public String notString(String str) {
if (str.startsWith("not"))
return str;
else
return "not " + str;
}
public String notString(String str) {
ReplyDeleteif (str.length()>=3&&str.substring(0,3).equals("not")) return str;
return "not " + str;
}
