Two methods of implementing a string. A counted string explicitly records its length. The terminated string’s length is determined by an end-of-string mark.

谁能给出一个java中计数字符串和终止字符串的例子吗？

Answer 1

CountedString {
   char[] string;
   int length;

   int getLength() {
     return length;
   }
}


TerminatedString {
   char[] string;
   final static char TERMINATOR = '$';
   int getLength() {
     for (int i = 0; i < string.length; i++) {
        if (string[i] == TERMINATOR) return i;
     }
   }
}
