public String whichIsLonger(String str1, String str2)

Given TWO strings, return the longer one.

  int len1 = str1.length();
  int len2 = str2.length();
  String longer = str1; // default, assume str1 is longer
  if (len2 > len1) { 
    longer = str2;  // if str2 is longer!
  }
  return longer;

OR

  int len1 = str1.length();
  int len2 = str2.length();
  if (len2 > len1) { 
    return str2; // if str2 is longer
  }
  return str1; // if str1 is longer
