// Get the current date and time
LocalDateTime now = LocalDateTime.now();

// Define the format
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

// Format the current date and time
String formattedNow = now.format(formatter);

// Print the formatted date and time
System.out.println("Current Timestamp:" + formattedNow);

Legacy Answer

Replace

new Timestamp();

with

new java.util.Date()

because there is no default constructor for Timestamp, or you can do it with the method:

new Timestamp(System.currentTimeMillis());
