java howto

how to install/configure and code in Java.

Install Java environment

First, download Eclipse (or NetBeans) development environment. Then you need Jave SE JDK, so download/install that. Now you have to start a project

install Java on a server

Debian doesn’t have Java 7 from Oracle/Sun after Squeeze, but you can install openjdk and it will compile and run java things, so do:

apt-get install default-jdk

Java IDE on your laptop

I use Eclipse, but there are many choices here. Still, Eclipse is pretty standard, so if you get stuck you might have a better chance of getting help.

apt-get install eclipse

Basic Java stuff

class whatever {
     public static void main(String args[]){
          girls = 13;
          boys = 3;
          people = girls + boys;
     System.out.println(people);
     }
}
