I have panel with 2 buttons in BoxLayout. What i want is to add vertical space between the buttons.
Here is my code:
frame = new JFrame("FreshPos baza podataka");
frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
JPanel panel = new JPanel();
panel.setBounds(new Rectangle(0, 5, 0, 0));
panel.setAlignmentY(Component.BOTTOM_ALIGNMENT);
frame.getContentPane().add(panel, BorderLayout.WEST);
panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
panel.setBorder( BorderFactory.createEmptyBorder(10,10,10,10) );
JButton btnNewButton_1 = new JButton("New button");
panel.add(btnNewButton_1);
JButton btnNewButton_2 = new JButton("New button");
panel.add(btnNewButton_2);
Add an invisible vertical component to the panel in between the two buttons:
JButton btnNewButton_1 = new JButton("New button");
panel.add(btnNewButton_1);
panel.add(Box.createVerticalStrut(50));
JButton btnNewButton_2 = new JButton("New button");
panel.add(btnNewButton_2);

I am setting up a UI for a blackjack helper program and while I know its not the most beautiful way to do things, it makes sense.
The layering for what seems to be the upper layers is not working properly. Any suggestions?
The left should have four layers, as should the middle and the right side should have two layers between the keypad and the enter buttons. Image is attached below.

The layering for what seems to be the upper layers is not working properly. Any suggestions? The left should have four layers.
A BorderLayout does not "layer".
Only a single component can be added to each of the 5 areas of the BorderLayout.
So, yes, you can create a JPanel and add multiple components to that panel, and then add the panel to an area of the BorderLayout.
JPanel rightSouthSide = new JPanel();
rightSouthSide.add(resetButton, BorderLayout.WEST);
rightSouthSide.add(enterButton, BorderLayout.EAST);
However, the above code is incorrect. The default layout manager of a JPanel is the FlowLayout. So specifying BorderLayout constraints does nothing (and is very confusing).
If by "layers" you mean "rows", then you need to use a panel with a different layout manage. Maybe you can use a BoxLayout to add rows of panels.
Overall, your approach to creating panels with different components is valid, the problem is you also need to use the appropriate layout manager for each of your child panels.
Read the Swing tutorial on Layout Managers for more information about how each of the layout managers work.

frame.setSize(300,300);

frame.setResizable(false);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
In the above example, I have created the three panels, and I have assigned all of them different heights. But all the three panels are taking more than assigned heights.
How to assign the different heights to different panels ?
Firstly: Instead of setSize() better use setPreferredSize() for your Panels
tfpanel.setPreferredSize(new Dimension(200,40));
panel2.setPreferredSize(new Dimension(200,60));
buttonpanel.setPreferredSize(new Dimension(200,120));
Secondly don't use GridLayout for your mainpanel because it makes all its components of same size. You could simply leave this line out
//mainpanel.setLayout(new GridLayout(0,1));
I need to make a program that ends up looking like this:
My code so far is what's posted and I can't seem to wrap my head around how to make this look exactly like the image I provided. I just don't really know what else I can do, I've tried looking around for solutions, but I can't manage to combine that information with this to make it all work together.
So, I hope somebody else can help me here, it'd be greatly appreciated! :D

I'd make that with 3 grid layouts and a border layout. E.G.
GridLayout for left/right sections (each section a panel)
GridLayout for buttons 1-6
BorderLayout for buttons 7-10 + panel in CENTER for..
GridLayout for buttons 11-18

Before Adding buttonPanel
After adding buttonPanel
I want to add button panel in the Middle-Bottom of the frame how can I do that?
Your grid layout only accounts for 5 components, so it's screwing up everything when you use 6. Add the buttonPanel to the sscp panel and then add the sscp panel to the overall Frame.
JPanel sscp= new JPanel();
sscp.setLayout(new FlowLayout(FlowLayout.LEFT));
JLabel sscper= new JLabel("Ssc Percentage",JLabel.LEFT);
JTextField sscperinput=new JTextField(3);
sscp.add(sscper);
sscp.add(sscperinput);
JPanel buttonPanel= new JPanel();
JButton save= new JButton("Save");
JButton cancel= new JButton("Cancel");
buttonPanel.add(save);
buttonPanel.add(cancel);
//change here
sscp.add(buttonPanel);
jf.add(sscp);
I want to align JButton instances vertically. Can you please suggest a way to do so?
Jbutton jb= new Jbutton();
Jbutton jb1= new Jbutton();
JButton jb3= new JBUtton();
Refer the code below:
private void prepareUI() {
this.setUndecorated(true);
//Preparing control buttons
JButton jb = new MyButton("-");
jb.setActionCommand("Min");
jb.addActionListener(this);
jb1 = new MyButton("[]");//delete this line
jb1.setActionCommand("Max");
jb1.addActionListener(this);
JButton jb2 = new MyButton("X");
jb2.setActionCommand("Close");
jb2.addActionListener(this);
//Preparing panel
JPanel buttonPanel = new JPanel();
BoxLayout boxLayout1 = new BoxLayout(buttonPanel, BoxLayout.Y_AXIS);
buttonPanel.setLayout(boxLayout1);
buttonPanel.add(Box.createVerticalGlue());
buttonPanel.add(jb);
buttonPanel.add(jb1);
buttonPanel.add(jb2);
jb.setFocusable(false);
jb1.setFocusable(false);
jb2.setFocusable(false);
JPanel panel=new JPanel();
BoxLayout boxLayout = new BoxLayout(panel, BoxLayout.LINE_AXIS);
panel.setLayout(boxLayout);
panel.add(Box.createHorizontalGlue())
