Stand Alone Classes
Hello forums,
Great Sunday ins't it?
So I've been working on a personal project. So far I've got a program that can create other individual stand alone programs (.java & .class) at any given location. I would like to double check on something. Since java is sending instructions to shell or cmd prompt, every time a new class is executed, we could say they are in their own independer runtime.
Is that correct?

Yes.
Re: Stand Alone Classes
Sup, helloworld922,
While I have you here I'd like to know something. Java's got writers and readers for files, streams, strings, and all. I know that the class files are the ones executed, but is it posible for the class to read itself?
Our code always starts with:
public static void main(String... args) { }
The args represents everything within the { }. I think I've heard the is a way to read whats in between { } and interpret or return a String instead of executing any of the instructions?
If so, do you have any idea on how to acomplish it? Any hint?
I found a similar question in the forums http://www.javaprogrammingforums.com...in-itself.html
Re: Stand Alone Classes
args does not represent what's between the brackets.
args is the parameters which are passed to the program from the command-line:
java some_class arg1 arg2
I hope that's the correct syntax, if not you get the idea.
args will now contain 2 String objects: "arg1", and "arg2".
I'm unaware of any way to extract the source from inside a method without the original source code, and even that can get dicey because you'll need to be able to correctly parse the Java code.
Re: Stand Alone Classes
Too complicated I guess.
What I am trying to achieve is for this program to create itself again (at some point of my project I'll add logic so that code would not always be the same but differentiates from the original), in addition of the code that makes a .java compilable.
I thought there was a more elegant way, but I guess I'll just have emuns type String containing java code.
