Java (1)

To study lumaqq (http://lumaqq.linuxsir.org), I decided to learn Java.

First download j2sdk. If you are interested, download eclipse

You can compileProgram. The first program:

// Helloworld. Java
Public class helloworld {
Public static void main (string ARGs []) {
System. Out. println ("Hello world! ");
}
}

Compile and execute:
Path = % PATH %; D: \ j2sdk1.4.2 _ 09 \ bin
Set classpath =.; D: \ j2sdk1.4.2 _ 09 \ Lib \ DT. jar; D: \ j2sdk1.4.2 _ 09 \ Lib \ tools. Jar
Javac helloworld. Java
