基本上 用settext 就可以了

我概略的寫一下


import java.awt.BorderLayout;
import javax.swing.JPanel;
import javax.swing.JFrame;
import javax.swing.JButton;

public class MineSweeper extends JFrame {

        private static final long serialVersionUID = 1L;
        private JPanel jContentPane = null;
        private JButton leftjButton = null;

        /**
         * This is the default constructor
         */
        public MineSweeper() {
                super();
                initialize();
        }

        /**
         * This method initializes this
         *
         * @return void
         */
        private void initialize() {
                this.setSize(300, 200);
                this.setContentPane(getJContentPane());
                this.setTitle("JFrame");
        }

        /**
         * This method initializes jContentPane
         *
         * @return javax.swing.JPanel
         */
        private JPanel getJContentPane() {
                if (jContentPane == null) {
                        jContentPane = new JPanel();
                        jContentPane.setLayout(new BorderLayout());
                        jContentPane.add(getLeftjButton(), BorderLayout.NORTH);
                }
                return jContentPane;
        }

        /**
         * This method initializes leftjButton
         *
         * @return javax.swing.JButton
         */
        private JButton getLeftjButton() {
                if (leftjButton == null) {
                        leftjButton = new JButton("A");
         leftjButton.addActionListener(new java.awt.event.ActionListener() {
                  public void actionPerformed(java.awt.event.ActionEvent e) {
                leftjButton.setText("B");
                                }
                        });
                }
                return leftjButton;
        }

}
