Writing functions in Java

Question

Hi there,
I'm pretty much a newbie to Java, but have had some experience with C++. I've been trying to write functions to use within the main class but they don't seem to work properly, although I have kinda found a solution, I just don't know if it's the right solution.
example
public class test
static int ival;
public static void init(void)
ival = 55;
public static void show(void)
System.out.println(ival);
public static void main(String []args)
test.ival();
test.show();
}not sure if that should work as I am writing it off the top of my head. The thing is I need to create a modular program that doesn't use other objects in it (otherwise I would just define them and use the member functions of the class definition to do the work that I need done). In terms of C++, the code I'm used to writing is more like this:
#include <iostream>
// prototypes
void init(void);
void display(void);
// main program
void main(void)
int var1;
init();
display();
// function definitions
void init(void)
var1 = 55;
void display(void)
cout<<var1<<endl;
}Then again, now that I look at the code, I don't know if the C++ code will work properly (*sigh*)... And people wonder why I prefer using PHP - no complications...
So if anyone can help clarify this for me, I would greatly appreciate it.
Many thanks,
Garatheus

There really isn't a "main class" in Java (and I don't recall C++ enough to compare); there's just classes potentially with main methods, which can be the starting point for execution as invoked by the JVM.
Also IIRC Java's OOP model is cleaner than C++'s -- to the point which you don't have standalone functions, just methods within a class.
Although maybe I shouldn't be posting here, as I've spent the last few years trying to forget C++.
