Java Code - Comparing last 4 letters -
implement method returns true if final 4 character substrings of s1
, s2
equal. if length of either string less 4, method should return false.
you may use method s.substring(n, m)
yields substring of s
beginning @ index n
, ending @ index m-1
.
as answer delivered following code, wondering whether did in correct way:
public static boolean comparelast4 (string s1, string s2) { s1len = s1.length; s2len = s2.length; if (s1lan < 4 || s2len < 4) return false; (int = 0; < s1len; i++) if (s1.substring() - 4.equals(s2.length() - 4)) return true; return false; }
i'd like:
public static boolean comparelast4 (string s1, string s2) { if (s1.length() < 4 || s2.length() < 4) return false; return s1.substring(s1.length() - 4).equals(s2.substring(s2.length()-4)); }
