I am trying to create a register form for my application(school project), I wanted to set the layout to BoxLayout but the Jtextfields and combo box is having issue as you can see below, does this issue relates to setSize() or is it something I am doing incorrect,I just want the Jtextfields sorts vertically , I appreciate the support
private JPanel SetUpRegister() {
JLabel registerLabel = new JLabel("Registera");
registerLabel.setFont(new Font("Arial", Font.BOLD, 30));
loginRegisterInput = new JTextField(INPUT_FIELD_WIDTH);
passwordRegisterInput = new JTextField(INPUT_FIELD_WIDTH);
fnRegisterInput = new JTextField(INPUT_FIELD_WIDTH);
lnRegisterInput = new JTextField(INPUT_FIELD_WIDTH);
ageRegisterInput = new JTextField(INPUT_FIELD_WIDTH);
String[] genderlist = new String[] { "Male", "Female", "Other" };
JComboBox<String> registerList = new JComboBox<>(genderlist);
JPanel registerPanel = new JPanel();
registerPanel.setBackground(new Color(255, 140, 0));
registerPanel.add(registerLabel);
registerPanel.add(loginRegisterInput);
registerPanel.add(passwordRegisterInput);
registerPanel.add(fnRegisterInput);
registerPanel.add(lnRegisterInput);
registerPanel.add(ageRegisterInput);
registerPanel.add(registerList);
registerPanel.setLayout(new BoxLayout(registerPanel,BoxLayout.Y_AXIS));
return registerPanel;
}
The input fields are huge
The BoxLayout will attempt to resize components when extra space is available on the panel. It will resize a component up to its maximum size.
For some reason the maximum height of a JTextField is Integer.MAX_VALUE which makes no sense to me, since the height of the text never changes as you enter more text.
In any case you have a couple of choices:
Use a different layout manager, like the GridBagLayout. The GridBagLayout, will respect the preferred size of the text fields.
Create a custom JTestField and override the getMaximumSize() method to return the preferred height of the component
Use a wrapper panel.
For the wrapper panel you could do:
JPanel wrapper = new JPanel( new BorderLayout() );
wrapper.add(registerPanel, BorderLayout.PAGE_START);
return wrapper;
//return registerPanel;
The BorderLayout will respect the preferred height of any component added to the PAGE_START, so there is no need for the BoxLayout to resize any component.

I fixed the issue by making a Panel for each input and label

I have the following Java GUI for my project. For some reason, the middle and right panels have been put below leaving empty spaces - marked in red. Is there a way to pull the panels up to fill the spaces.
These empty spaces does not look good. I have tried to check all code but cannot pinpoint where to correct.
Thanks in advance.

I have solved the problem by using Borderlayout and assigning the main panel to it.
The assigning the WEST, CENTER and EAST regions to it.
I have added the code below in the code above at places where the main panel is being added to.
Thank you for the advice to start debugging by using MRE approach.

I was trying to build UI in IntelliJ but it was hard so I tried to build it in Eclipse. Now UI looks little better but still poor. One of chart (the cener one) should be biger and second one on south should be smaller but flat and long. I tried to use preffered size or validate or repaint but still nothing. How to anchor them to side borders, and avoid to cover them self?

As your code is not MCVE I could not run it with changes, but I think your problem is bad layout settings. For example, you create a new JPanel:
JPanel jpSouth = new JPanel();
FlowLayout flowLayout_1 = (FlowLayout) jpSouth.getLayout();
flowLayout_1.setAlignment(FlowLayout.TRAILING);
You are aware that it is using FlowLayout by defaul, by later you use:
jpSouth.add(jfcPanelSouth,BorderLayout.CENTER);
but you never change layout to BorderLayout. You cannot mix layout of one particular container. But this is not what couse you problem directly.
Your BorderLayout.SOUTH area stretch horizontally, to fit components inside, and BorderLayout.CENTER takes all spece left(or not). This is how those parts of BorderLayout works. So you can change where you put particular components, or change layout at all.
I suggest to try with:
JPanel jpCenter = new JPanel(new BorderLayout());
...
jpCenter.add(jfcPanelCenter,BorderLayout.NORTH);
...
jpCenter.add(jfcPanelSouth,BorderLayout.SOUTH); //not to contentPane!
this will change an arrangement. However I am not sure, is it what you want. If not, try with different layout, for example BoxLayout.
Also I would rather use pack() and set size of components, than setBounds on a countainer.
You can also use GUI builders, like Netbeans IDE GUI Builder if you want to create GUI but don't care how.
I am new to java. I am trying to implement scroll feature to my Jpanel but the schoolpane is not visible. I tried to many methods but nothing works.

Thanks.
Your scrollBar is not visible because it is not necessary. If you change JScrollPane settings, for example:
scrollBar.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS);
scrollBar.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
you will see you have it, but not use it. It is because your scrollBar doesn't have a content which expands dynamically (like JTextArea for example). Your scrollBar has JPanel inside, which has size to fit all its components, so it will not be enough to add some text inside text components.
To make scroll bars visible, you can change a size of JSrollPane. However setBound() will not work if you JPanel use default FlowLayout. To use absolute positioning in JPanel you need to use null layout, what is generally not recommended and is seen as bad programming practice.
Try to delete setBound() lines and use for example scrollBar.setPreferredSize(new Dimension(400,555)); instead. You should see a difference.
I tried to do this from stackoverflow:
adding multiple jPanels to jFrame
But that didn't seem to work out like in the example, could anyone tell me what im doing wrong?
Im trying to add multiple JPanels with each their own sizes to the JFrame. I was also hoping it was possible to give each JPanel specific sizes and ability to put them on the exact spot i want.

As discussed here, don't set the size and position of components arbitrarily. Instead, let the layout do the work, nesting as required. Use the GroupLayout shown here for the labeled input fields. Add each to the CENTER of a panel having BorderLayout, with a button in the SOUTH on the left. Finally, add both panels to an enclosing panel having GridLayout(1, 0).
I am trying to create a GUI using JPanels that have a GridLayout. The fromPanel works perfectly, but the toPanel will only add the JTextFields. The code for the panels is almost exactly the same so I'm not sure why one works but the other doesn't. I have tried changing either rows or columns to 0, but the JLabels still don't show up in the toPanel.
Here is my code:
public class Driver extends JFrame{
private int WIDTH = 800, HEIGHT = 500, WIDTH2 = 350;
private JPanel toPanel, fromPanel, sizePanel, messagePanel, deliveryPanel,
totalPanel, bottomPanel;

private JTextField toFirstText, toLastText, toStreetText, toCityText, toStateText, toZipText,
fromFirstText, fromLastText, fromStreetText, fromCityText, fromStateText, fromZipText;
public Driver(){
