この GUI を実行したいのですが、クラスからオブジェクトを作成しようとすると、型 GUI をインスタンス化できませんというエラーが表示されます。それで、それはどういう意味ですか、どうすれば修正できますか？
メインクラスのコード
public static void main(String[] args){
//Classes
GUI go = new GUI();
//Running Class Methods
//JFrame
//JFrame frame = new JFrame("Yatsy");
go.setVisible(true);
go.setVisible(true);
//go.setLocation((dim.width - width) / 2, (dim.height - height) / 2);
go.setSize(width, height);
System.out.println(width + " " + height);
//draw paint = new draw();
//go.add(paint);
}
GUI クラス内のコード
public GUI(){
super();
panel = new JPanel();
roll = new JButton("Roll");
nextPlayer = new JButton("Next Player");
bDice1 = new JButton("dice");
quit = new JButton("Quit");
use = new JButton("Use");
roll.addActionListener(
new ActionListener(){
public void actionPerformed(ActionEvent event){
if(turn == true){
rollResult1 = roll1();
rollResult2 = roll2();
rollResult3 = roll3();
rollResult4 = roll4();
rollResult5 = roll5();
sRollResult1 = Integer.toString(rollResult1);
sRollResult2 = Integer.toString(rollResult2);
sRollResult3 = Integer.toString(rollResult3);
sRollResult4 = Integer.toString(rollResult4);
sRollResult5 = Integer.toString(rollResult5);
rolls++;
start = false;
repaint();
System.out.println( rollResult1 + " " + rollResult2 + " " + rollResult3 + " " + rollResult4 + " " + rollResult5);
//System.out.println( rollAI );
}
if(rolls == 3){
turn = false;
System.out.println("Out of rolls");
}
}
});
nextPlayer.addActionListener(
new ActionListener(){
public void actionPerformed(ActionEvent event){
if(rolls > 0){
rolls = 0;
System.out.println("Next player");
turn = true;
repaint();
start = true;
}
}
});
quit.addActionListener(
new ActionListener(){
public void actionPerformed(ActionEvent event){
System.exit(0);
}
});
add(panel, BorderLayout.CENTER);
panel.setBackground(Color.BLUE);
add(quit, BorderLayout.SOUTH);
add(roll, BorderLayout.NORTH);
add(nextPlayer, BorderLayout.EAST);
Handlerclass handler = new Handlerclass();
panel.addMouseListener(handler);
}
では、なぜエラーが発生するのでしょうか。
私はJava 1.7を使用しています！
これが完全なコードであることを知りたい人のために!!!!
