Hi there,
A few weeks until I begin my journey towards a degree in Computer
Science at Canterbury University in New Zealand,
Anyway the course tutors are going to be teaching us JAVA wth bluej and
I was wondering if anyone here would be able to give me some tips for
young players such as myself, for learning the language.
Is this the best Newsgroup for support with JAVA?

Hi people,
I am just learning java.I have been creating a project which involves JDBC Connectivity.I find that the statements,
String string_dob=text_dob.getText();
//Converting string to date
System.out.println(string_dob);
s.Info_DOB=Date.valueOf(string_dob);
runs perfectly fine in the method insert() and throws up an illegal Exception in the method UPDATE.This is the error I get when I pass a date "1979-05-02"

I am getting this error message in the program I'm working on (line 150), and am wondering what it means? This is an exercise for a college class; just want to declare that; this is not my own work.
Here is the program that I am working with:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
