How to get JButton below the JTextFields

I have created a GridLayout for my GUI to show 6 rows and 4 columns. I am trying to get the two buttons I have "Calculate" and "Exit" to show in the 6th row. I only have two pane.add of four for row 5 (which is the weight label and textfield). I'm just trying to get the calculate and exit buttons to be on their own row. I tried to do pane.add(); to fill the gap and couldn't get it to work. What am I missing so that I can get the buttons on their own row?
basically I have
pane.setLayout(new GridLayout(6, 4));
pane.add(score1L);
pane.add(score1TF);
pane.add(weight1L);
pane.add(weight1TF);
pane.add(score2L);
pane.add(score2TF);
pane.add(weight2L);
pane.add(weight2TF);
pane.add(score3L);
pane.add(score3TF);
pane.add(weight3L);
pane.add(weight3TF);
pane.add(score4L);
pane.add(score4TF);
pane.add(weight4L);
pane.add(weight4TF);
pane.add(weightAvgL);
pane.add(weightAvgTF);
pane.add(calculateB);
pane.add(exitB);

Possible options:
Add empty JLabels to fill in any gaps.
Use mixed layouts -- nest JPanels, each using its own layout and add components to them. For example, the overall JPanel could use BorderLayout. The textfields/labels could be in a GridLayout or GridBagLayout using JPanel added BorderLayout.CENTER to the main JPanel. The JButtons could be held in their own GridLayout using JPanel that is then added BorderLayout.PAGE_END to the main JPanel.
Use a layout manager that allows for more complex layouts such as a GridBagLayout, or better perhaps, a 3rd party layout manager such as MigLayout.
Perhaps the best of all --use a JTable to hold your data grid, add it to a JScrollPane, and then place your buttons below the JScrollPane.

Display Form in ScrollPane

I created a form. Actually it is 10 JLabels with each JLabel having a text field next to it.
consider,
JLabel_called_Name JTextField_to_obtain_name
JLabel_called_Phone JTextField_to_obtain_phone_number
and so on..
I usually position this in a JPanel and display it in a frame. But my panel and frame have height smaller than the size required to hold 10 of these Labels and Textfields.
So I wish to add them to a JScrollPane.
But in every question I only obtained information of how to add Jlabels to a scroll pane using a Box,
or adding JLabels to a JList.
However I would like to represent it in the format I showed above. A Jlabel beside a JTextField.
How can one acheive this?

You can add any component to a JScrollPane:
JPanel = new JPanel();
panel.add( label1 );
panel.add( textField1 );
JScrollPane scrollPane = new JScrollPane( panel );
The trick is choosing the correct layout manager for you panel. Read the Swing tutorial on Layout Managers to help you decide how to design the panel. You can also nest panels to get your desired layout.

How do I add ScrollPane to a panel in Java?

I want to add different buttons, vertically stacked, to a JPanel at run-time and use a JScrollPane so that all buttons will be visible (with some scrolling).
In order to do this, I have added my JPanel to a JScrollPane, after which I add buttons to my JPanel.
However, when I do this the vertical scrollbar does not allow me to see all images. For example when I add 7 buttons I can only scroll to see 5 full images and half of the 6 images.
Why doesn't my scrollbar allow me to display all 7 buttons?

Create the panel and scrollpane like:
JPanel panel = new JPanel();
JScrollPane scrollPane = new JScrollPane( panel );
When you add buttons to the panel at run time the code should be:
panel.add( button );
panel.revalidate();
As long as you are using a layout manager the preferred size will be recalculated and the scrollbar will appear.

Make scroll pane a wrapper over your panel - new JScrollPane (myPanel) and add it instead of naked panel in your panel's container.
You also may want to play with its setPreferredSize() method.

Scrollable flow panel

I need to create a panel where I can put some rectangles and it automatically reorder just inserting a scrollbar and growing up vertically. Also this panel can be resizable and again the rectangles must to be reordered to correctly be displayed inside the panel.

If I understand the question you want components to wrap to the next line so that the panel grows vertically while the width remains fixed.
If so then check out the WrapLayout
Note: the FlowLayout already supports the wrapping of components to a new row on the panel. This issue is that the preferred size calculation assumes all components are placed on a single row. The WrapLayout overrides the preferred size calculation to support the wrapping of components on a new row.

Use a JScrollPane. If you never want a horizontal scroll bar you can add the following:
scrollPane.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
(By default the scroll pane will add horizontal and vertical scroll bars when required.)
The scroll pane itself will only be resizeable if you add it to a Container with the appropriate layout manager; e.g.
JFrame frm = new JFrame();
frm.setLayout(new BorderLayout());
JScrollPane sp = new JScrollPane();
frm.add(sp, BorderLayout.CENTER); // Adding a component to the CENTER will cause the component to grow as the frame is resized.

Can you set a permanent size for a JPanel inside of a JFrame?

My current problem is that I have a JFrame with a 2x2 GridLayout. And inside one of the squares, I have a JPanel that is to display a grid. I am having a field day with the java swing library... take a look
Image
Java is automatically expanding each JLabel to fit the screen. I want it to just be those blue squares (water) and the black border and not that gray space. Is there a way I can just set the size of that JPanel permanently so that I don't have to go through changing the size of the JFrame a million times before I get the exact dimension so that the gray space disappears?
I also would like to set the size of those buttons so they are not so huge (BorderLayout is being used for the buttons and TextField)

GridBagLayout is what you really want to use. The GridLayout will force the same size for each component in the layout no matter what size constraints you put on them. GridBagLayout is a lot more powerful and a lot more complicated. Study up on the API page for it. Using GridBagLayout, the components won't fill the whole grid space if you don't want them to and can even stay the size that you ask it to be. To keep a component's size from changing, I would set all three available size constraints:
water.setPreferredSize(new Dimension(20, 20));
water.setMinimumSize(new Dimension(20, 20));
water.setMaximumSize(new Dimension(20, 20));
For your buttons, I would definitely use an inner panel as Bryan mentions. You could use either a GridLayout like he suggests or a FlowLayout if you don't want all the buttons to be the same size. Add all your buttons to that inner panel instead of the main one.

If you want the two checkerboards to stay the same size, then you'll need to have them each contained in their own JPanel. Set each of those parent JPanel's to have a layout type of GridBagLayout. Set the preferedSize for each checkerboard component and then add them to their respective containers. GridBagLayout should by default lay each board out in the center of the parent JPanel. So as the window is resized, the JPanel parent area will get larger or smaller, but the checkerboard components inside will remain the same size.
Alternatively, you could have your blue squares scale to the right size as the window is resized by having each checkboard square be a JPanel with a BorderLayout layout manager and adding the JLabel (with a blue background color) to its BorderLayout.CENTER location.
As for your buttons, try something like this:
JPanel theButtonPanel = new JPanel(new BorderLayout());
JButton button1 = new JButton("Fire");
JButton button2 = new JButton("Pass");
JButton button3 = new JButton("Forfiet");
JPanel innerButtonContainer = new JPanel(new Grid(1, 3, 8, 8));
innerButtonContainer.add(button1);
innerButtonContainer.add(button2);
innerButtonContainer.add(button3);
theButtonPanel.add(innterButtonContainer);
Lastly, consider using a design tool for your Swing user interface. Netbeans has an excellent UI designer built into it. Download Netbeans here.

If you can setResizeable( false ) on the top level frame you can then set your layout manager to null and hard code each location and size via setBounds. This is how I would do it (contingent on resizing of course).

I have had success solving problems like these using TableLayout which is a third party layout manager. You will need to download it and read the tutorial but the key would be to set the justification to CENTER when adding the JButtons to their positions in the layout.
