Hi,
You have asked about constructors in IO.
You should know that which "Writer" and "OutputStrem " class is used to append a file(without overwriting an existing file) and their parameter.
Nothing about pushback, Linenumbers , StringTokenizers etc. Concentrate only "File" related I/O donot over load your brain for the exam purpose. Infact after attending exam you will realize that so called advanced topics will be easier than other simple topics.
You should know which character based writer/reader is used for specific encoding (not only default encoding) Study thoroughly about File class and its methods.(You can go through Kalid certification book that books covers more than required for exam)
In Collections you should know only the fundamentals about when to use Set, List, Map and their implementing classes.
Do not neglect the loops, Strings(immutability), StringBuffers etc.
One usual Garbage collection question which has almost become a standard question like a
String literal is pointed by two references, one is set to null (normally you will think that GC will be working here) but one more refernce will still be still pointing that string when that become null only GC will act.
Finally you can expect almost one sure question from SUN site
java cerification sample questions.
I will be regularly visiting this discussion and other
JDBC,
JSP,
Servlets discussion also.
once again thanks
