Questions:
1. in HttpTokenizer.java, at the line:
if (t==StreamTokenizer.TT_WORD)
what is StreamTokenizer.TT_WORD? A private data member of the class StreamTokenizer (which can't be, unless I'm wrong)? A method of the class StreamTokenizer (which can't be, since http://java.sun.com/j2se/1.3/docs/api/java/util/StringTokenizer.html is not missing anything)?
2. in HttpTokenizer.java, at the line:
return this.nextToken;
The method nextToken in HttpTokenizer says "public int" so how can a "return this.nextToken()" return a String when the method demands it to return an int?
3. For the class Reader (http://java.sun.com/j2se/1.3/docs/api/java/io/Reader.html), the method read() (http://java.sun.com/j2se/1.3/docs/api/java/io/Reader.html#read()) will "Read a single character" but what do we do with that int? Why is that int in the range 0 to 65535 (0x00-0xffff)? What does that range of 0 to 65535 (0x00-0xffff) mean/indicate?
This question applies likewise to the return object of (primitive) type int in HttpTokenizer.java. |
