Open another form

Hi.

I'm using NetBeans IDE 6.8, and this is my first program in Java in maby 3 years.

Now I have made two packages, and in this packages I have made two files(JDialog Forms):
*boot - main.java
*login - login.java

How can I now from login.java(Package: login) open the file main.java (Package: boot) ?

And whats the difference between JDialog Form and JPanel Form ?

Because I have working in Visual Basic and a bit in C++ before, and there I only used Windows Form Application, so which one of these would be most like that?

Neither a JDialog nor a JPanel is a form, a JDialog is a dialog, a JPanel is a panel, A JFrame or a JWindow are somewhat like windows forms.

You can add multiple JPanels to a JFrame. To show the JFrame or a JDialog just call it's "setVisible" method and pass true in the args list. Just like in VB or any OO language, you have to instantiate the class before calling its methods
