How to give spaces between jlabel?
Hi i am trying to make java desktop application where i am using multiple jlabel i want to give little spaces between every label
how can i achieve this
here is my code
public class Second extends javax.swing.JFrame {
JLabel label=new JLabel();
/**
* Creates new form Second
*/
public Second() {
this.getContentPane().setBackground(new java.awt.Color(255, 140, 0));
this.setExtendedState(JFrame.MAXIMIZED_BOTH);
this.setUndecorated(true);
JButton print= new JButton();
print.setBackground(new java.awt.Color(153, 153, 0));
print.setOpaque(true);
print.setBounds(525,1282,130,85);
print.setFont(new java.awt.Font("Times New Roman", 1, 24)); // NOI18N
print.setForeground(new java.awt.Color(255,255,255));
print.setText("Print");
this.add(print);
JButton home= new JButton();
home.setBackground(new java.awt.Color(153, 153, 0));
home.setOpaque(true);
home.setBounds(640,1282,130,85);
home.setFont(new java.awt.Font("Times New Roman", 1, 24)); // NOI18N
home.setForeground(new java.awt.Color(255, 255,255 ));
home.setText("Home");
this.add(home);
int Height = 134;
int a=100;
ArrayList<JLabel> label = new ArrayList<JLabel>();
for(int i=0;i<23;i++){
JLabel j = new JLabel();
j.setBackground(new java.awt.Color(255, 140, 255));
j.setOpaque(true);
j.setBounds(5,Height,378,50);
j.setFont(new java.awt.Font("Times New Roman", 1, 16)); // NOI18N
j.setForeground(new java.awt.Color(128, 128, 128));
j.setText("Case Item CourtNo ");
LineBorder line = new LineBorder(Color.blue, 2, true);
j.setBorder(line);
this.add(j);
label.add(j);
JLabel j1 = new JLabel();
j1.setBackground(new java.awt.Color(255, 140, 0));
j1.setOpaque(true);
j1.setBounds(390,Height,768,50);
j1.setFont(new java.awt.Font("Times New Roman", 1, 16)); // NOI18N
j1.setForeground(new java.awt.Color(128, 128, 128));
j1.setText("Case Item CourtNo ");
this.add(j1);
label.add(j1);
Height = Height +50;
a=a+10;
}
initComponents();
}
public void paint(Graphics g) {
super.paint(g);
Graphics2D g3 = (Graphics2D) g;
BasicStroke bs = new BasicStroke(2);
Line2D lin1 = new Line2D.Float(386, 100, 386, 1282);
Line2D lin = new Line2D.Float(0, 1283, 768, 1283);
Line2D line3=new Line2D.Float(400,1284,400,1364);
g3.setStroke(bs);
g3.setColor(Color.white);
g3.draw(lin1);
g3.draw(lin);
g3.draw(line3);;
}
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {

new Second().setVisible(true);
}

CompoundBorder compound = new CompoundBorder(line, border);
for (int i = 0; i <12; i++) {

updated Thanks in advance
Answer
"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.
Learn to use the different layout managers at Laying out Components Within a Container
