// 聲明標簽

// 聲明初始化按鈕
JButton getButton = new JButton("得到一個隨機數");// 獲取隨機數按鈕

FlowLayout g = new FlowLayout(FlowLayout.LEFT, 10, 10);

// 聲明面板

public GameFrame() {
    this.setSize(400, 300);
    this.setTitle("猜數字小游戲");
    Container c = this.getContentPane();
    GridLayout f = new GridLayout(4, 2, 10, 10);

    getButton.setSize(100, 100);

    p1.add(Getlb);

    // 設置程序可視化及關閉
    this.setVisible(true);
    this.setDefaultCloseOperation(3);

    // 給按鈕設置監聽器
    getButton.addActionListener(this);
    confButton.addActionListener(this);
}

// 實現actionPerformed接口方法
public void actionPerformed(ActionEvent e) {
    // TODO 自動生成的方法存根
    int count = 0;// 初始化計數器

    if (e.getSource() == getButton) {
        number = (int) (Math.random() * 100) + 1;
        getButton.setEnabled(false);
    }
    if (e.getSource() == confButton) {
        int guessnumber = Integer.parseInt(jtf.getText());

        if (guessnumber > number) {

            Rightlb.setText("猜大了！");

        }
        if (guessnumber < number) {

            Rightlb.setText("猜小了！");

        }

        if (guessnumber==number) {

            Rightlb.setText("猜對了！你一共猜了" + count + "次");
        }
    }
}

}
想了好幾種方法都不行，如何設置計數器統計猜測次數呢？

最佳回答：

類中定義一個 靜態 int 變量，每次猜測的時候，++就好了
