import javax.swing.JOptionPane;

public class windowss{
    public static void main(String[] args){
        String aa;
        aa=JOptionPane.showInputDialog("please enter a number:");
        String bb;
        bb=JOptionPane.showInputDialog("plese enter a number:");
        int a;
        a=Integer.parseInt(aa)+Integer.parseInt(bb);;
        String outstr;
        JOptionPane.showMessageDialog(null,"the result is:"+a,"try",JOptionPane.INFORMATION_MESSAGE);
        System.exit(0);
    }
}

showInputDialog( String),一个输入对话框
showMessageDialog(String);一个显�C�消息的对话�?
