Compiling "HelloWorld.java" on Slackware 10.2

halfpower · 09-07-2006, 08:55 AM

I have the following java program on my hard drive

Code:

public class HelloWorld { 

   public static void main(String[] args) { 
        System.out.println("Hello, World");
   }

}

I've tried typing the command

Code:

$ gcj HelloWorld.java

but all I get is this

Code:

$ gcj HelloWorld.java
/usr/lib/gcc-lib/i486-slackware-linux/3.3.6/../../../crt1.o(.text+0x18): In function `_start':
../sysdeps/i386/elf/start.S:115: undefined reference to `main'
collect2: ld returned 1 exit status

This is simple code. Can anyone tell me why it is not compiling?
