To set maximized bounds, use the setMaximizedBounds() method. Here, we will create a frame, which when maximized will form a shape −JFrame frame = new JFrame("Login!");Above, we have created a frame and now we will use the Rectangle class to specify an area of coordinates −Rectangle bounds = new Rectangle(50, 10, 100, 200); Now, set maximized bounds − frame.setMaximizedBounds(bounds);The following is an example to set the maximized bounds for a frame −Examplepackage my; import java.awt.GridLayout; import java.awt.Rectangle; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPasswordField; import javax.swing.JTextField; import javax.swing.SwingConstants; public class SwingDemo {    public static void main(String[] args) throws Exception { ...

To disable the close button, let us first create a frame −JFrame frame = new JFrame("Login!");Use the setDefaultCloseOperation() to set the status of the close button. Set it to DO_NOTHING_ON_CLOSE to disable it −frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);The following is an example to disable close button on a JFrame in Java −Examplepackage my; import java.awt.GridLayout; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPasswordField; import javax.swing.JTextField; import javax.swing.SwingConstants; public class SwingDemo {    public static void main(String[] args) throws Exception {       JFrame frame = new JFrame("Login!");       JLabel label1, label2, label3;       frame.setLayout(new GridLayout(2, 2));       label1 = ...

Position buttons vertically one after another using the Box class. Use the createVerticalBox() method that displays components from top to bottom −JButton button1 = new JButton("One"); JButton button2 = new JButton("Two"); JButton button3 = new JButton("Three"); Box box = Box.createVerticalBox(); box.add(button1); box.add(button2); box.add(button3);The following is an example to position buttons vertically one after another −Examplepackage my; import javax.swing.Box; import javax.swing.JButton; import javax.swing.JFrame; public class SwingDemo {    public static void main(String[] args) {       JButton button1 = new JButton("One");       JButton button2 = new JButton("Two");       JButton button3 = new JButton("Three");       ...

To set the text of the label component to be right- justified and vertically centered, you need to set the alignment while creating a new label.Set the label to be on the right -JLabel label = new JLabel("Name", JLabel.RIGHT);Here, we have set the size of the label as well as the color that includes foreground and background color -label.setPreferredSize(new Dimension(170, 70)); label.setOpaque(true); label.setBackground(Color.MAGENTA); label.setForeground(Color.WHITE);The following is an example to set the text of the label to be right-justified and vertically centered −Examplepackage my; import java.awt.Color; import java.awt.Dimension; import java.awt.FlowLayout; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JTextArea; import javax.swing.WindowConstants; public ...

Set the alignment of the label’s content along the Y axis on the bottom, use the setVerticalAlignment() method and set the location. Let us first set a label component. We have set the label background color as well so that we can check the alignment of the label’s content properly  −JLabel label = new JLabel("Project Name"); label.setPreferredSize(new Dimension(190, 100)); label.setOpaque(true); label.setBackground(Color.GREEN); label.setForeground(Color.WHITE);Now, we will align the label content along the Y axis on the bottom by seeting location as BOTTOM −label.setVerticalAlignment(JLabel.BOTTOM);The following is an example to set the alignment of the label content along the Y axis in the bottom ...

Use the createHorizontalStrut() method to create an invisible width component between two components. Let’s say we have some button and we are creating a fixed width between them −box.add(button4); box.add(Box.createHorizontalStrut(50)); box.add(button5); box.add(Box.createHorizontalStrut(30)); box.add(button6);The following is an example to create an invisible fixed width component between two components −Examplepackage my; import java.awt.BorderLayout; import javax.swing.Box; import javax.swing.BoxLayout; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JScrollPane; public class SwingDemo {    public static void main(String args[]) {       JFrame frame = new JFrame("Groups");       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       JButton button1 = new JButton("CSK");       JButton button2 = new JButton("DC"); ...

To set different height for multiple rows, use the setRowHeight() method for separate rows for which you want to increase the row height. Let us first see an example to create a table with same height for all the rows −Examplepackage my; import java.awt.Color; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.table.DefaultTableModel; public class SwingDemo {    public static void main(String[] argv) throws Exception {       DefaultTableModel tableModel = new DefaultTableModel();       JTable table = new JTable(tableModel);       tableModel.addColumn("Language/ Technology");       tableModel.addColumn("Text Tutorial");       tableModel.addColumn("Video Tutorial");     ...
