Java
This is the code I provided for the problem
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 don't know why I did it
Editor: I edited more codes according to your requirements
Solution
You declare 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 in a class as follows:
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"; ...
