So, where did you get this code from?
I haven't put it into any of my editors but what happens when you put that main method inside that main class and try to compile and run it?

[carlos123]

i wrote this code in bluej ( a beginer program)

public class main implements ActionListener
{

error: class main is public , should be declared in a file named main.java

[carlos123]

basically, i need help with this program, but too fully understand the problem, the people who want to help me, actually will have to put this code into their own editor and compile it themselves to see whats actually wrong with it.

thanks.

[r035198x]

i wrote this code in bluej ( a beginer program)

public class main implements ActionListener
{

error: class main is public , should be declared in a file named main.java

In Java you can have only one public class in a source file. Either have each of your classes in separate files or remove the public modifier from all of then (you can leave the one whose name matches name of the source file if you want).

[carlos123]

I still dont understand what you mean

[carlos123]

I want to do the second option

[r035198x]

I still dont understand what you mean

I thought you said that you wrote this program. So you should understand what I mean by a public class because you wrote the code with the public classes.
I have already explained what the second option entails. Removing the public access modifier from the headers of your classes.

[carlos123]

ugh..................................

[r035198x]

ugh..................................

What now?
Perhaps if you explain the part of my reply that you didn't understand ...

[carlos123]

what should i put instead of "public class"

and i know i should know this, but i dont.

[r035198x]

what should i put instead of "public class"

and i know i should know this, but i dont.

In "public class", public is the access modifier. So when I say remove the public class modifier, I mean change "public class" to just "class".

P.S Are we later on going to get to a point when you say that you are actually not the one who wrote this code?

[carlos123]

I did write this code, in bluej, but i have yet to learn how to like make it all one giant code together. its a hall pass program for a class that i have

[carlos123]

thanks bro. now on to the real problem, check out my new thread ;)
