我写的 MS，MR，MC以及M+功能，自己改改吧

private JButton getJButton24() {
if (jButton24 == null) {
jButton24 = new JButton();
jButton24.setFocusable(false);
jButton24.setBounds(new Rectangle(3, 156, 46, 35));
jButton24.setMargin(new Insets(0, 0, 0, 0));
jButton24.setText("MR");
jButton24.setForeground(new Color(51, 51, 252));
jButton24.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent e) {
str=String.valueOf(m);
jTextField1.setText(str+".");
}
});
}
return jButton24;
}

/**
* This method initializes jButton25
*
* @return javax.swing.JButton
*/
private JButton getJButton25() {
if (jButton25 == null) {
jButton25 = new JButton();
jButton25.setFocusable(false);
jButton25.setBounds(new Rectangle(3, 114, 46, 35));
jButton25.setMargin(new Insets(0, 0, 0, 0));
jButton25.setText("MC");
jButton25.setForeground(new Color(51, 51, 252));
jButton25.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent e) {
m=0;
jToggleButton1.setText("");
}
});
}
return jButton25;
}

/**
* This method initializes jButton26
*
* @return javax.swing.JButton
*/
private JButton getJButton26() {
if (jButton26 == null) {
jButton26 = new JButton();
jButton26.setFocusable(false);
jButton26.setBounds(new Rectangle(3, 197, 46, 35));
jButton26.setMargin(new Insets(0, 0, 0, 0));
jButton26.setText("MS");
jButton26.setForeground(new Color(51, 51, 252));
jButton26.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent e) {
m=Double.parseDouble(jTextField1.getText());
jToggleButton1.setText("M");
}
});
}
return jButton26;
}

/**
* This method initializes jButton27
*
* @return javax.swing.JButton
*/
private JButton getJButton27() {
if (jButton27 == null) {
jButton27 = new JButton();
jButton27.setFocusable(false);
jButton27.setBounds(new Rectangle(4, 238, 46, 35));
jButton27.setMargin(new Insets(0, 0, 0, 0));
jButton27.setText("M+");
jButton27.setForeground(new Color(51, 51, 252));
jButton27.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent e) {
m+=(double)Double.valueOf(jTextField1.getText());

}
});
}
return jButton27;
}

追问

不用RMS吗？那记忆功能是如何实现的呀

追答

MS是将当前屏幕上的文字存取，MC是将存取的数删除，MR是提取存取的数到屏幕，M+是将当前屏幕的文字与存取的数相加，并存到缓冲区

能看看我的代码然后用类似的方法做吗？我的程序里就没有jButton。。。。
