Thread: Having difficulties with Java for the first time...

I just recently have started programming with Java (I first learned programming with Visual Basic and Pascal) but I'm having difficulty trying to understand how to make Java work on my systems. I cen't even get a simple "Helloworld" java program to compile in the JRE, even with the #code compiler with Windows 11. I open a DOS prompt but I can't get the executable to run the simple program. Anyone have any advice in what I'm doing wrong?

You can test basic java code in this browser environment

Cool site! Still having problems with my code I entered into the website. Here is the snipet of code I'm using...

/*
* Hello World
* The classic first program
*/

public class main {

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

I tried a few varitations of this on the website, but no success yet. Any advice?

Ok, here is what it looks like in the browser....

/*
* Hello World
* The classic first program
*/
 
public class main {
 
public static void main(String[] args) {
System.out.println("Hello, world!");
}
}
 
Main.java:6: error: class main is public, should be declared in a file named main.java
public class main {
       ^
1 error

Not sure why its saying the class main is the problem.
