Thread: Program to run as Applet & Application - need fresh eye's simple mistake somewhere

Basically this is a rock paper scissors game in a simple gui. The program works in applet form, but when I tried this method to run as an application, nothing happened.

This is the applet (below is my method to run as an application.)

import java.awt.*; import java.awt.event.*; import javax.swing.*; import java.util.Random; import javax.swing.JApplet;     /** rock paper scissors class */ public class JRockPaperScissors extends JApplet{	// Variables declaration     private JLabel titleLbl; private JLabel selectionLbl;	private JLabel resultsLbl;	private JTextArea resultTextArea;	private JButton rockBn;	private JButton paperBn;	private JButton scissorBn;	private Container contentPane; private int cpu = 0; private int wins = 0; private int loses = 0; private int ties = 0; private final int CHOICE_MAX = 3; private final int ROCK = 0; private final int PAPER = 1; private final int SCISSORS = 2; private Random rand = new Random();  	public JRockPaperScissors(){	initializeComponent();	} /** initializing componets */	private void initializeComponent()	{	titleLbl = new JLabel();	selectionLbl = new JLabel();	resultsLbl = new JLabel();	resultTextArea = new JTextArea();	rockBn = new JButton();	paperBn = new JButton();	scissorBn = new JButton();	contentPane = getContentPane();  	//	// titleLbl	//	titleLbl.setText("Rock, Paper, Scissors"); titleLbl.setFont(new Font("Garrmond", Font.BOLD, 30));	//	// selectionLbl	//	selectionLbl.setText("Choose one"); selectionLbl.setFont(new Font("Arial",Font.BOLD,14));	//	// resultsLbl	//	resultsLbl.setText("*****Results*****"); selectionLbl.setFont(new Font("Arial",Font.BOLD,14));	//	// resultTextArea	//      	//	// rockBn	//	rockBn.setText("Rock");	rockBn.addActionListener(new ActionListener() {	public void actionPerformed(ActionEvent e)	{	rockBn_actionPerformed(e);	}  	});	//	// paperBn	//	paperBn.setText("Paper");	paperBn.addActionListener(new ActionListener() {	public void actionPerformed(ActionEvent e)	{	paperBn_actionPerformed(e);	}  	});	//	// scissorBn	//	scissorBn.setText("Scissors");	scissorBn.addActionListener(new ActionListener() {	public void actionPerformed(ActionEvent e)	{	scissorBn_actionPerformed(e);	}  	});	//	// contentPane	//	contentPane.setLayout(null);	addComponent(contentPane, titleLbl, 5,9,370,47);	addComponent(contentPane, selectionLbl, 9,54,150,35);	addComponent(contentPane, resultsLbl, 9,93,144,38);	addComponent(contentPane, resultTextArea, 5,132,398,111);	addComponent(contentPane, rockBn, 162,58,78,31);	addComponent(contentPane, paperBn, 247,58,81,31);	addComponent(contentPane, scissorBn, 334,58,87,31);	contentPane.setSize(new Dimension(435, 290));	//	// JRockPaperScissors	//  	setSize(435, 290);	setVisible(true);	}  	/** Add Component Without a Layout Manager (Absolute Positioning) */	private void addComponent(Container container,Component c,int x,int y,int width,int height)	{	c.setBounds(x,y,width,height);	container.add(c);	}  	/** action event methods */	private void rockBn_actionPerformed(ActionEvent e)	{ //play the game choosing rock play(ROCK);	}  	private void paperBn_actionPerformed(ActionEvent e)	{ //play the game choosing paper play(PAPER);	}  	private void scissorBn_actionPerformed(ActionEvent e)	{ //play the game choosing scissors play(SCISSORS);	} //method to play the game private void play(int pick){ String resultStr = ""; //random computer choice cpu = rand.nextInt(CHOICE_MAX); //nested if statments to determine winner loser or tie if(pick == cpu){ ties++; resultStr = "You picked " + selection(pick) + " ---- Computer picked " + selection(cpu); resultStr += "\nWinner: Tie"; resultStr += "\nYou: " + Integer.toString(wins) + " " + "Computer: " + Integer.toString(loses) + " Ties: " + Integer.toString(ties); resultTextArea.setText(resultStr); } else if( (pick == ROCK) && (cpu == SCISSORS) ){ wins++; resultStr = "You picked " + selection(pick) + " ---- Computer picked " + selection(cpu); resultStr += "\nWinner: You"; resultStr += "\nYou: " + Integer.toString(wins) + " " + "Computer: " + Integer.toString(loses) + " Ties: " + Integer.toString(ties); resultTextArea.setText(resultStr); } else if( (pick == PAPER) && (cpu == ROCK) ){ wins++; resultStr = "You picked " + selection(pick) + " ---- Computer picked " + selection(cpu); resultStr += "\nWinner: You"; resultStr += "\nYou: " + Integer.toString(wins) + " " + "Computer: " + Integer.toString(loses) + " Ties: " + Integer.toString(ties); resultTextArea.setText(resultStr); } else if( (pick == SCISSORS) && (cpu == PAPER) ){ wins++; resultStr = "You picked " + selection(pick) + " ---- Computer picked " + selection(cpu); resultStr += "\nWinner: You"; resultStr += "\nYou: " + Integer.toString(wins) + " " + "Computer: " + Integer.toString(loses) + " Ties: " + Integer.toString(ties); resultTextArea.setText(resultStr); } else{ loses++; resultStr = "You picked " + selection(pick) + " ---- Computer picked " + selection(cpu); resultStr += "\nWinner: Computer"; resultStr += "\nYou: " + Integer.toString(wins) + " " + "Computer: " + Integer.toString(loses) + " Ties: " + Integer.toString(ties); resultTextArea.setText(resultStr); }   } //function returns paper rock or scissors as a string public String selection(int choice){ String tempStr; switch(choice){ case 0: tempStr = "rock"; break; case 1: tempStr = "paper"; break; case 2: tempStr = "scissors"; break; default: tempStr = "invalid"; } return tempStr; }   }

I thought in theory, this would work to run it as an application.

public class Game{	public static void main(String[] args)	{	JRockPaperScissors test = new JRockPaperScissors;	} }

I am so stumped on what I did wrong...

Thank you so much!! I knew i needed fresh eyes on this. I had one question though for future reference. Now that everything runs correct, why does it hang for a bit? Or how can I figure that part out?

java.lang.ClassCastException: JRockPaperScissors cannot be cast to java.applet.Applet	at sun.applet.AppletPanel.createApplet(AppletPanel.java:785)	at sun.applet.AppletPanel.runLoader(AppletPanel.java:714)	at sun.applet.AppletPanel.run(AppletPanel.java:368)	at java.lang.Thread.run(Thread.java:662)

This is the error I get in debugging. I think this is the cause of the hanging.

This error I am getting, is it because JRockPaperScissors is not defined??

java.lang.ClassCastException: JRockPaperScissors cannot be cast to java.applet.Applet	at sun.applet.AppletPanel.createApplet(AppletPanel.java:785)	at sun.applet.AppletPanel.runLoader(AppletPanel.java:714)	at sun.applet.AppletPanel.run(AppletPanel.java:368)	at java.lang.Thread.run(Thread.java:662)

This is the error, and it seems like when it reads the JRockPaperScissors(). It does not error in complie, but it errors when you run as applet in debug.

OHHHHHHHHHHHHHH!!!! Omg... I have been looking at this way to long....
