Java Homework Question

I've been working on a Java project for school but I'm am having trouble with the JFrame Layout. The items are not being put where I am programming them to be, and sometimes they don't even show up unless I re-size the window.

Also, I have a random number generator that generates a number between 1 and 6. Would I be able to display a different JPanel depending on the number that the generator gave me? Thanks in advance!

Here's what I what the layout to look like

 

Guessing you're not allowed to use Netbeans to create the GUI?

Just use a switch statement and change the layout/show a different frame for each case,

Code:

swtich(randNumInt) {
case 0 :
//set layout
break;
}

 

To expand on what iJava was saying about displaying the JPanels you could just call setVisible() on each of them to make one visible and one invisible instead of an if or switch statement. ( http://docs.oracle.com/javase/6/docs/api/javax/swing/JComponent.html#setVisible(boolean) )

Code:

if(something) {
 panel1.setVisible(true);
 panel2.setVisible(false);
}
else {
 panel1.setVisible(false);
 panel2.setVisible(true);
}

For the layout stuff have a look at the Java tutorial for different layout managers. You will probably have to make use of more than one to do the kind of thing you showed there. You can always post further questions if you get stuck again preferably with some code or screenshot of GUI.

What type of layout are you currently using?

The panel thing can be worked out with a simple if after random number is generated and as ^ said, set the number to the label and display the panel that has it

 

Thanks everyone for your help, I found a another program that let me design the layout much easier and I got the JPanel's to do what I want. Thanks again!
