How to give spaces between jlabel?

Question 1

"How to give spaces between jlabel?"

setBounds and null layouts: no; Use EmptyBorders: YES!; Use LayoutManagers: YES!

"how can i use this can u explain little bit "

Use can use the default FlowLayout of the containing JPanel (or in this case set the gaps of the FlowLayout)

FlowLayout constructor:

public FlowLayout(int align,
      int hgap,
      int vgap)

align - the alignment value

hgap - the horizontal gap between components and between the components and the borders of the Container

vgap - the vertical gap between components and between the components and the borders of the Container

Example

JPanel panel = new JPanel(new FlowLayout(FlowLayout.CENTER, 20, 5);
for (int i = 0; i < 10; i++) {
    panel.add(new JLabel("Label" + i));
}

You could use EmptyBorder

EmptyBorder constructor

public EmptyBorder(int top,
       int left,
       int bottom,
       int right)

top - the top inset of the border

left - the left inset of the border

bottom - the bottom inset of the border

right - the right inset of the border

Example

JPanel panel = new JPanel();
for (int i = 0; i < 10; i++) {
    JLabel label = new JLabel("Label" + i);
    EmptyBorder border = new EmptyBorder(5, 20, 5, 20);
    label.setBorder(border);
    panel.add(label);
}

If you want to use a LineBorder and an EmptyBorder for margins, you can use a CompoundBorder

A composite Border class used to compose two Border objects into a single border by nesting an inside Border object within the insets of an outside Border object. For example, this class may be used to add blank margin space to a component with an existing decorative border:

CompoundBorder Example

JPanel panel = new JPanel();
EmptyBorder border = new EmptyBorder(5, 20, 5, 20);
LineBorder line = new LineBorder(Color.blue, 2, true);
CompoundBorder compound = new CompoundBorder(line, border);
for (int i = 0; i < 10; i++) {
    JLabel label = new JLabel("Label" + i);
    label.setBorder(compound);
    panel.add(label);
}

There is an abundant number possibilities. Choose your flavor. The whole point it no not try and set size and position to everything, and make use of layout managers and borders and gaps for sizing, spacing etc.

Full example using CompoundBorder and GridLayout(int rows, int cols, int hgap, int vgap)

enter image description here

import java.awt.Color;
import java.awt.GridLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import javax.swing.border.CompoundBorder;
import javax.swing.border.EmptyBorder;
import javax.swing.border.LineBorder;

public class CompoundBorderDemo {

    public CompoundBorderDemo() {
        JFrame frame = new JFrame();
        JPanel panel = createPanel();
        frame.add(panel);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

    private JPanel createPanel() {
        JPanel panel = new JPanel(new GridLayout(5, 5, 10, 10));
        EmptyBorder panelBorder = new EmptyBorder(10, 10, 10, 10);
        panel.setBorder(panelBorder);
        EmptyBorder border = new EmptyBorder(5, 20, 5, 20);
        LineBorder line = new LineBorder(Color.blue, 2, true);
        CompoundBorder compound = new CompoundBorder(line, border);
        for (int i = 0; i < 25; i++) {
            JLabel label = new JLabel("Label" + i);
            label.setBorder(compound);
            panel.add(label);
        }
        return panel;
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                new CompoundBorderDemo();
            }
        });
    }
}

Question 2

Try using layouts like GridLayout instead of setting bounds to every label.

it is the simplest solution for your problem.Grid Layout May suit you better.
