java - Swing：将数据从 JFrame 传递到另一个

Question

我的程序中有 2 个表单，一个是显示应用程序启动时间的基本应用程序表单，第二个是用于将实体添加到数据库的表单。它直观地工作：在默认表单中单击add按钮，第二个表单显示，您填写一些文本区域并单击done按钮。

我的问题，如何将数据从第二种形式传递到第一种形式？

Answer 1

method 1 :
1 : create 1 form
2 : add all fields for entering fields and also the fields from the confirmation form
3 : hide the confirmation fields
4 : when user clicks submit , hide the fields of first form , show the fields of second form

thus you all the data in one form only and you can handle the data as you want

ohk then lets try this

create a form 1
create a form 2
create a bean class having all the fields from form 1
now create a simple main class calling form 1
when user submits the form 1 , take all the values from form1 , create an object of the bean , store the values in the bean object , thus you are still in the main class 
after setting the values in the bean , call the form 2 frame , and set the fields in form 2 by using the same object of the bean class
