Java Question

Syntax error on tokens, delete these tokens

Here is my code that has been giving the problems.

package ca.rhinoza.game;

import java.awt.BorderLayout;
import java.awt.Canvas;
import java.awt.Dimension;

import javax.swing.JFrame;

public boolean running = false;


public class Game extends Canvas implements Runnable {

private static final long serialVersionUID = 1L;

public static final int WIDTH = 160;
public static final int HEIGHT = WIDTH / 12 * 9;
public static final int SCALE = 3;
public static final String NAME = "Game";

private JFrame frame;

public Game(){
setMinimumSize(new Dimension(WIDTH*SCALE, HEIGHT*SCALE));
setMaximumSize(new Dimension(WIDTH*SCALE, HEIGHT*SCALE));
setPreferredSize(new Dimension(WIDTH*SCALE, HEIGHT*SCALE));

frame = new JFrame(NAME);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());

frame.add(this, BorderLayout.CENTER);
frame.pack();

frame.setResizable(false);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}

public synchronized void start(){

new Thread(this).start();

}

public synchronized void stop(){

}

public void run() {


}


public static void main(String[] args){

new Game().start();
}


}


I have no idea why it is doing this.

Edit:
I edited as per your request to see more code.

Answer

You are declaring a field outside the class:

import java.awt.BorderLayout;
import java.awt.Canvas;
import java.awt.Dimension;

import javax.swing.JFrame;

public boolean running = false; /// <=============== invalid location 


public class Game extends Canvas implements Runnable { // <==== class starts here
    private static final long serialVersionUID = 1L;

    public static final int WIDTH = 160;
    public static final int HEIGHT = WIDTH / 12 * 9;
    public static final int SCALE = 3;
    public static final String NAME = "Game";
    ...

It must be placed inside a class, like below:

import java.awt.BorderLayout;
import java.awt.Canvas;
import java.awt.Dimension;

import javax.swing.JFrame;


public class Game extends Canvas implements Runnable { // <==== class starts here

    public boolean running = false; /// <=============== valid location

    private static final long serialVersionUID = 1L;

    public static final int WIDTH = 160;
    public static final int HEIGHT = WIDTH / 12 * 9;
    public static final int SCALE = 3;
    public static final String NAME = "Game";
    ...
