The valueOf() method of the java.sql.Timestamp class accepts a String value representing a time stamp in JDBC escape format and converts the given String value into Timestamp object.Timestamp timeStamp = Time.valueOf("timeStamp_string");ExampleLet us create a table with name dispatches_data in MySQL database using CREATE statement as shown below:CREATE TABLE dispatches_data(    ProductName VARCHAR(255),    CustomerName VARCHAR(255),    DispatchTimeStamp timestamp,    Price INT,    Location VARCHAR(255));Now, we will insert 5 records in dispatches_data table using INSERT statements:insert into dispatches_data values('Key-Board', 'Raja', TIMESTAMP('2019-05-04', '15:02:45'), 7000, 'Hyderabad'); insert into dispatches_data values('Earphones', 'Roja', TIMESTAMP('2019-06-26', '14:13:12'), 2000, 'Vishakhapatnam'); insert into dispatches_data values('Mouse', 'Puja', TIMESTAMP('2019-12-07', '07:50:37'), 3000, 'Vijayawada'); insert into ...

Set frame.dispose() on the click of a button to close JFrame. At first create a button and frame −JFrame frame = new JFrame(); JButton button = new JButton("Click to Close!");Now, close the JFrame on the click of the above button with Action Listener −button.addActionListener(e -> {    frame.dispose(); });The following is an example to close JFrame on the click of a Button −Exampleimport java.awt.Color; import java.awt.Dimension; import javax.swing.JButton; import javax.swing.JFrame; public class SwingDemo {    public static void main(String[] args) {       JFrame frame = new JFrame();       JButton button = new JButton("Click to Close!");   ...

In this article, we will learn how to display a frame after a few seconds in Java using the Timer class. This example shows how to delay the visibility of a frame by 2 seconds using Swing. Timer() class The Timer class is used to schedule tasks that execute after a specific time interval or repeatedly at regular intervals. It allows tasks to be run by a thread that handles the scheduling and execution. Each task can be set to execute either once or repeatedly at fixed intervals. The execution of all tasks is managed by a background thread associated ... Read More

At first, create a JFrame −JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setPreferredSize(new Dimension(550, 300));Now, change the background color of the JFrame −frame.getContentPane().setBackground(Color.BLUE);The following is an example to change JFrame background color −Exampleimport java.awt.Color; import java.awt.Dimension; import javax.swing.JFrame; public class SwingDemo {    public static void main(String[] args) {       JFrame frame = new JFrame();       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       frame.setPreferredSize(new Dimension(550, 300));       frame.getContentPane().setBackground(Color.BLUE);       frame.pack();       frame.setVisible(true);    } }Output

Mnemonic key is set so that a user can use Keyboard keys to select a Radio Button. For example, a key can be set with ALT −radio2.setMnemonic(KeyEvent.VK_R);Above, we have set key ALT+R for radio2.The following is an example to set Mnemonic key radio button −package my; import java.awt.FlowLayout; import java.awt.event.KeyEvent; import javax.swing.ButtonGroup; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JRadioButton; public class SwingDemo {    public static void main(String[] args) {       JRadioButton radio1 = new JRadioButton("Male");       JRadioButton radio2 = new JRadioButton("Female");       radio2.setMnemonic(KeyEvent.VK_R);       ButtonGroup group = new ButtonGroup();       ...

In this article, we will learn about creating a vertical progress bar using JProgressBar.VERTICAL in Java. Progress bars are essential for tracking task completion in GUI applications, and a vertical orientation can add a unique touch to your design. What is a Progress Bar in Java Swing? A progress bar is a visual component in Java Swing that indicates the progress of a task. It can be horizontal or vertical, depending on the application's design requirements. Java Swing provides the JProgressBar class to create and manage progress bars efficiently. Features of a Vertical Progress Bar The following are features of ... Read More

Use the setBounds() method to set Bounds for JProgressBar in Java Swing −JProgressBar progressBar; progressBar.setBounds(70, 50, 120, 30);The following is an example to set bounds for JProgressBar −Examplepackage my; import javax.swing.*; public class SwingDemo extends JFrame {    JProgressBar progressBar;    int i = 0;    SwingDemo() {       progressBar = new JProgressBar(0, 1000);       progressBar.setBounds(70, 50, 120, 30);       progressBar.setValue(0);       progressBar.setStringPainted(true);       add(progressBar);       setSize(550, 150);       setLayout(null);    }    public void inc() {       while (i

To disable a JLabel, use the setEnabled() method −JLabel label; label.setEnabled(false);The following is an example to disable a JLabel −package my; import java.awt.Color; import java.awt.Dimension; import java.awt.Font; import javax.swing.*; import javax.swing.border.Border; public class SwingDemo {    public static void main(String args[]) {       JFrame frame = new JFrame("Demo");       JLabel label;       label = new JLabel("First Label", JLabel.RIGHT);       label.setVerticalAlignment(JLabel.TOP);       label.setFont(new Font("Verdana", Font.PLAIN, 15));       label.setPreferredSize(new Dimension(250, 100));       label.setForeground(new Color(120, 90, 40));       label.setBackground(new Color(100, 20, 70));       label.setEnabled(false);   ...
