CALLING ANOTHER PROGRAM

**jeboi** · October 5th, 2012, 04:48 AM

Need some help
I have 2 java programs
TicTacToe.java(2 player mode)
TicTacToeAI.java(AI mode)

I plan to create a java menu bar for the 2 programs

I have this:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
 
public class FinalProject extends JFrame implements ActionListener
{
 
 
 public FinalProject()
 {
MenuBar menuBar = new MenuBar();
setMenuBar(menuBar);
 
Menu menuFile = new Menu("Game", true);
menuBar.add(menuFile);
MenuItem menuTTT = new MenuItem("Versus Mode");
menuFile.add(menuTTT);
MenuItem menuTTTAI = new MenuItem("Versus AI");
menuFile.add(menuTTTAI);
 
Menu menuAbout = new Menu("About", true);
menuBar.add(menuAbout);
MenuItem menuAboutTicTacToe = new MenuItem("About TicTacToe");
menuAbout.add(menuAboutTicTacToe);
 
menuTTT.addActionListener(this);
menuTTTAI.addActionListener(this);
menuAboutTicTacToe.addActionListener(this);
 
menuTTT.setActionCommand("Versus Mode");
menuTTTAI.setActionCommand("Versus AI");
menuAboutTicTacToe.setActionCommand("About");
 }
 
public void createAndShow()
 {
  setDefaultCloseOperation(EXIT_ON_CLOSE);
  setPreferredSize(new Dimension(100, 80));
  setLocation((1000/2), (400/2));
  pack();
  setVisible(true);
 }
 
 
 
 
public void actionPerformed(ActionEvent e)
{
 
String arg = e.getActionCommand();
    if (arg == "Versus Mode")
{
 
}
 
    if (arg == "Versus AI")
{
 
}
 
 
    if (arg == "About")
{
    String message = "Elson's TicTacToe\nComputer Programming II\nCopyright 2011\nAll rights reserved";
    JOptionPane.showMessageDialog(null,message,
    "The Programmer", JOptionPane.INFORMATION_MESSAGE);
}
}
 
 
public static void main(String[] args)
 {
  FinalProject frame = new FinalProject();
  frame.createAndShow();
 }
 
}

how can I call the 2 programs and insert here:

public void actionPerformed(ActionEvent e)
{
 
String arg = e.getActionCommand();
    if (arg == "Versus Mode")
{
 
}
 
    if (arg == "Versus AI")
{
 
}

Please edit you post and wrap the code in code tags.

if (arg == "Versus Mode")
{

You should use the equals() method to compare Strings.
It would be better to compare the source of the event or to use a String variable that is used in two places than to use two Strings that could be different if you mistype it.

I did what you ask but how can i call two java programs
e.g.
If I press "Versus Mode" = TicTacToe.java(2 players) will come out
If I press "Versus AI" = TicTacToeAI.java will come out

how can i call two java programs

You call methods in a class, not programs.
Get a reference to the class that has the method and use it to call the method:
refToClass.theMethod();

**jeboi** · October 5th, 2012, 08:03 AM

e.g.

I'll call TicTacToe() to be put here:

String arg = e.getActionCommand();
    if (arg == "Versus Mode")
{
 
}

and I'll call TicTacToeAI() here:

}
 
    if (arg == "Versus AI")
{

or you can post a simple code here so that I can easily understand what will I do

Are those classes or methods that you want to call? You need to explain which.
Have instances of those two classes been created? If so where are the variables that point to those instances? If there are instances of the class, you call a method in the class like this:

if(<some condition>) {
   refToClass.theMethod();
   ...
}

If they have not been created then you could create them inside the if statements:

if(<some condition>) {
   TheClassYouWantToCreate tcls =new TheClassYouWantToCreate();  // create an instance calling the class's constructor
   tcls.theMethod(); // Call the method
  ...
}

How to insert here calling the class or method?

String click = e.getActionCommand();
    if (click.equals("Versus Mode"))
{
 
}
 
    if (click.equals("Versus AI"))
{
 
}

**Norm** · October 6th, 2012, 08:44 AM

What method do you want to call? Those classes have several methods in them.
Is there a reference to an instance of the class with that method available in the if statements where you want to call that method?
Or do you want to call the class's constructor?

I gave some samples in post#6.

**jeboi** · October 6th, 2012, 09:06 AM

in the menubar if a user clicks the 'Game' 2 options will come out
Versus mode and Versus AI

If the user will click the 'Versus Mode' TicTacToe.java will appear
If the user will click the 'Versus AI' TicTacToeAI.java will appear

and I dont know what class or methods will be called
Can you help me

**Norm** · October 6th, 2012, 09:13 AM

TicTacToe.java will appear

Your terminology is confusing. Classes like JFrame can cause GUI items to appear on the screen as windows.
The source file: TicTacToe.java does not appear. The source file contains the definition of a class that can be compiled and executed.

I dont know what class or methods will be called

If you don't know what you want to do, how can anyone know? Can you explain?

Are you asking how to call the constructor for the TicTacToe class?
You can do that by using the new statement. There is an example in post#6

TheClassYouWantToCreate tcls = new TheClassYouWantToCreate(); // create an instance calling the class's constructor

**jeboi** · October 6th, 2012, 09:23 AM

It would be like this

String click = e.getActionCommand();
    if (click.equals("Versus Mode"))
{
 TicTacToe ttt =new TicTacToe();
   ttt.theMethod();
}
 
    if (click.equals("Versus AI"))
{
 TicTacToeAI tttai =new TicTacToeAI();
   tttai.theMethod();
}

**Norm** · October 6th, 2012, 10:09 AM

That could work.
Did you try it? What happened?

The method theMethod() is undefined

The compiler can not find a method named: theMethod() in the class: TicTacToe
What method in the class are you trying to call? Check the class definition for the methods that it defines.

     win = true;
   }
   else if(button[2].getText() == button[4].getText() && button[4].getText() == button[6].getText() && button[2].getText() != ""){
     win = true;
   }
 
   return true;
 }
 
 
 public void newGameDialog(){
   if(player.equals("P1"))
     p1wins++;
   else
     p2wins++;
 
   int response = JOptionPane.showConfirmDialog(null, "Do you want a new game?", "Confirm", JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE);
   if(response == JOptionPane.YES_OPTION)
   reset();
   else{
   System.exit(0);
   }
 
 }
 
   public void reset(){
     for(int i=0;i<=8;i++){
       button[i].setText("");
       button[i].setEnabled(true);
     }
 
     win = false;
     count = 0;
     sign = 0;
 
 
 
 
 
   }
}

so this must be TicTacToe()

so I change 'theMethod()' to 'TicTacToe()'

{
  TicTacToe ttt =new TicTacToe();
   ttt.TicTacToe();    
}

but same error:

1 error found:
File: E:\FinalProject1.java [line: 54]
Error: The method TicTacToe() is undefined for the type FinalProject1.TicTacToe

I want to call

You can call either a class's constructor or a method in a class or both.
What method in the class do you want to call? Look at the class definition and find the method you want to call.

The method TicTacToe() is undefined

The compiler can not find the method TicTacToe() in the class: TicTacToe.

Where did you get these classes? Can you ask the person that wrote the classes how to use them?
