public class Practice extends JFrame implements ActionListener{
Button btnEnter;
public static void main(String[] args){
Practice frame = new Practice();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setBounds(50, 50, 900, 700);
frame.setTitle("研究のGUI");
frame.setVisible(true);
}
Practice(){
JPanel p = new JPanel();
btnEnter = new Button("追加");
btnEnter.addActionListener(this);
add(btnEnter);
btnEnter.setBounds(250,120,80,80);
getContentPane().add(p, BorderLayout.CENTER);
appRun();
}
public void appRun(){

public void actionPerformed(ActionEvent e){
Button bt = (Button)e.getSource();
if(bt==btnEnter){
