New Java and want to talk theory

hello,

I been programming for 7 months now and I am the stage when I want to know what Java can really do. I am fasicating with making a program that can connect to the internet and do things. I just don't know where to begin... As an example, when you buy a new car or phone you play around with it and find all the new features and become a better user. In the same sense, I would like to do that with programming in java. For example, I would love to create a program that pays bills online automically etc... Basically what can java do in regards to networking?


I just completed a program for my wife's business and it writes to excel, keeps tracking of our inventory, does our book keeping and I am quite happy with it, but it would be nice if the program could keep track of exchange rates between Japan and the US. This would be very exciting to do. I do not know where to begin to learn this. Talking about it gets me very excited, but I don't know where to start learning about the networking side.

It would be nice to talk to someone about the possiblities that Java can provide.

Java has alot of possiblities but i yet have to get to the networking part of java.
I suggested to keep making basic programms to practice and add and try new stuff.

I am trying to learn c++ too so i could do more stuf. :D
Althoug it is hard and realy diffrent then Java

Oracle has a Tutorial which aims at being quite comprehensive. There's a section on Custom Networking. I know that when I started using Java (way back!) one of the things I first noticed and liked was the ability to read and write to urls somewhat like files. Nowadays that's a commonplace but at the time it seemed like it opened up a whole world.
