how do i call on a class with (graphics g)

Mon, 26 Apr 2010 16:52:45 -0700

im trying to create the game mastermind and in my version, i split the many parts of my code into separate classes so it would be a
little easier to work with, several of my classes use g.drawstring for animation and positioning purposes,(got the idea from c++ gotoxy) but when i try to call some of these classes it gives me an (java.awt.Graphics) can not be applied to () error. what should i do?.

below is the mainmenu class i am trying to call and the mastermind class that is calling it.

~~~~~~~~~~~~~~~~~~~MAINMENU~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~

import java.awt.Graphics;
import javax.swing.*;
import java.awt.*;

public class mainmenu
{
public void mainmenu(Graphics g)

{
int Position=0;int row=0;

for(row=30;row>=0 ;row=row-1)
{
for( Position=20;Position>=0;Position=Position-57)
{ g.drawString("************************************ *********************",row+0,0);

}
}

~~~~~~~~~~~~~~~~~~~~~~~~~~MASTERMIND~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~

import java.awt.Graphics;
import java.util.Scanner;
import javax.swing.*;
import java.awt.*;
import java.util.Random;

public class MASTERMIND {

public static void mastermind ( String [] args){
Scanner reader = new Scanner(System.in);

/* like i said there are alot of parts to it */

starter s = new starter();
mainmenu m = new mainmenu();
window w = new window();
endscreen e = new endscreen();
endscreen2 q = new endscreen2();
easy x = new easy();
Easy_game_instructions k = new Easy_game_instructions();
Hard_game_instructions h = new Hard_game_instructions();
endcreditz p = new endcreditz();
instructionscreen i = new instructionscreen();
winningscreen b = new winningscreen();
easy_game y = new easy_game();
hard_game u = new hard_game();
quitpfz a = new quitpfz();

int userselection=0;

s.starter();

while ((userselection!=5))
{
m.mainmenu(); /*<=< THIS IS WHERE THE ERROR IS */

switch(userselection)
{
case 1:i.instructionscreen();break;
case 2:y.easy_game();break;
case 3:u.hard_game();break;
case 4:p.endcreditz();break;
case 5:b.winningscreen();
}

}

}
}

~~~~~~ any help would be greatly appreciated, thank you ~~~~~~~

Hey,
You have outlined an ambitious endeavor. My recommendations are not use the draw functions because their information is not preserved when a window component is automatically redrawn by the "system".

I altered your program to show a simple window frame. However the program is not meant to be a template. GUI programming is pretty involved.

My personal suggestion is to view a TicTacToe program (click on the link) that could provide many insights. I tried the version in the second post, it looked good just need to fix 1 line: public cl*** TicTacToe implements ActionListener {
needs to be: public class TicTacToe implements ActionListener {

A modified version of your original program is attached for download.

regards, se52
