Java creating a new frame

public static void main(String[] arguments){
    TicTac frame = new TicTac();
}

The second TicTac says cannot find symbol and asks to create constructor TicTac();.

My constructer is as follows: 

public TicTac(TicTac in) {

}

I have tried 

TicTac frame = new TicTac(TicTac in);

Here is the whole code:

import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.*;
import tictactoe.TicTac;


public class TicTac extends JFrame implements ItemListener, ActionListener, Runnable{
    TicTac gui;
    Thread playing;
    TicTacEvent tictac = new TicTacEvent(this);
    JPanel row1 = new JPanel();
    JButton[][] boxes = new JButton[3][3];
    JButton play = new JButton("Play");
    JTextField blank1 = new JTextField();
    JTextField blank2 = new JTextField();
    JOptionPane win = new JOptionPane("Winner");
    ImageIcon back = new ImageIcon("cardback.jpg");
    ImageIcon a = new ImageIcon("x.jpg");
    ImageIcon b = new ImageIcon("o.jpg");
    int clicks = 0;
    //int win = 0;
    int winX = 0;
    int winO = 0;
    int tie = 0;
    int[][] check = new int[3][3];

    public TicTac(TicTac in) {
        super ("Tic Tac Toe");
        gui = in;
        setSize (500,600);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        FlowLayout layout = new FlowLayout();
        setLayout(layout);
        int name = 0;
        String newname;

        for (int row=0; row<=2;row++){
            for(int col=0; col<=2; col++){
                check[row][col]=0;
            }
        }

        row1.setLayout(layout1);
        for (int x=0; x<=2; x++){
            for (int y=0; y<=2; y++){
                name = name + 1;
                newname = Integer.toString(name);

To fix my problem I created a separate class. Class one:

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

public class TicTac extends JFrame {

 JButton play = new JButton("Play"); 
 JTextField blank1 = new JTextField(); 
 JTextField blank2 = new JTextField(); 
 JOptionPane win = new JOptionPane("Winner"); 
 ImageIcon back = new ImageIcon("cardback.jpg"); 


 public TicTac() { 
 super ("Tic Tac Toe"); 
 setSize (500,600); 
 setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
 FlowLayout layout = new FlowLayout(); 
 setLayout(layout); 
 int name = 0; 
 String newname; 

 GridLayout layout1 = new GridLayout(4, 3, 10, 10); 
 row1.setLayout(layout1); 
 for (int x=0; x<=2; x++){ 
 for (int y=0; y<=2; y++){ 
 name = name + 1; 
 newname = Integer.toString(name); 
 boxes[x][y] = new JButton(newname); 
 boxes[x][y].setIcon(back); 
 row1.add(boxes[x][y]); 
 } 
 } 
 row1.add(blank1); 
 row1.add(play); 
 row1.add(blank2); 
 add (row1); 

 play.addActionListener(tictac); 
 for (int x=0; x<=2; x++){ 
 for (int y=0; y<=2; y++){ 
 boxes[x][y].addActionListener(tictac); 
 } 
 }  

 setVisible(true); 
 } 

 public static void main(String[] arguments){ 
 TicTac frame = new TicTac(); 
 } 
}

Your constructor requires you to pass in an existing TicTac as a parameter. In the code you show, you're trying to create a TicTac without doing so.

As @MadProgrammer points out, requiring a TicTac to create a TicTac creates something of a catch-22 situation: How can you ever create one without having one first? If, for some reason, you do need to create a TicTac with a reference to an existing TicTac, you need to create an additional constructor with no parameters (as your compiler is suggesting) to create the first one:

 public TicTac() {  }

(more accurately, your constructor can take parameters, it just cant require a TicTac):

class TicTac { 
    public TicTac(int size) { }
    public TicTac(TicTac otherTicTac) { }
    ...
 }
 //elsewhere: 
 TicTac first = new TicTac(5);  //or just TicTac first = new TicTac() 
 TicTac second = new TicTac(first);

However, I'm guessing that you don't really need a TicTac(TicTac otherTicTac) constructor (if so, tell me why), and that you're trying to do so as a result of a misunderstanding about how constructors work - in which case this might be a helpful read, for starters.
