我先是定义了一个窗体1，在上面有个按钮，后来又定义了一个窗口2，现在想点击一下这个按钮，显示窗体2并且关闭窗体1！请教如何实现啊？
这个很简单，自己看看书就是了！
这个太简单了 google 就好了
还没实现关闭窗体1
public class Apple
{
JFrame from1 = new JFrame("窗体1");
JFrame from2 = new JFrame("窗体2");
JPanel pan = new JPanel();
JButton but = new JButton("打开");
public Apple()
{
but.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0)
{
if(arg0.getSource() == but)
{
from2.setSize(200, 200);
from2.setVisible(true);
}
}
});
this.pan.add(but);
from1.setLayout(new BorderLayout());
from1.add(this.pan);
from1.setSize(300, 300);
from1.setVisible(true);
}
public static void main(String[] args)
{
new Apple();
}
}
