Hi,
I'm new to java, but experienced in other OO languages.....
My first question deals with the interface java.io.DataOutput/Input
... in the writeUTF() method....where is the spec for what a UTF format is, and what is the % overhead for these higher level IO methods?. vs individual chars
at the stream level?
My second Question is with the following server and client code....(JDK-1.0 )
They both work well on Solaris, but running on win95 it locks up ( 96 client messages, 1 server message ). Is this a limitation/bug on win95, garbage collection, an error in the code?
Thanks!
