To automatically transfer data entered from a JFrame form to Excel and automatically print it, you can use the following steps:
1. Create a JFrame form with text fields for the data you want to transfer to Excel.
2. Add a button to the JFrame form that will trigger the transfer and printing process.
3. In the button's action listener, create an instance of the Apache POI library's Workbook class, which represents an Excel workbook.
4. Create a new sheet in the workbook by calling the createSheet() method on the workbook instance.
5. Obtain the data entered in the text fields of the JFrame form by calling the getText() method on each text field.
6. Write the data to the Excel sheet by calling the createRow() and createCell() methods on the sheet instance.
7. Save the workbook to a file by calling the write() method on the workbook instance.
8. Print the file by using the Java Print API.
Here is a sample code snippet that implements these steps:
Note that you will need to add error handling to this code to handle exceptions that may occur during file I/O or printing.

// Obtain data from text fields
String name = nameTextField.getText();
int age = Integer.parseInt(ageTextField.getText());
String address = addressTextField.getText();
// Create workbook and sheet
Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Data");
// Write data to Excel sheet
Row row = sheet.createRow(0);
Cell cell = row.createCell(0);
cell.setCellValue("Name");
cell = row.createCell(1);
cell.setCellValue("Age");
cell = row.createCell(2);
cell.setCellValue("Address");
row = sheet.createRow(1);
cell = row.createCell(0);
cell.setCellValue(name);
cell = row.createCell(1);
cell.setCellValue(age);
cell = row.createCell(2);
cell.setCellValue(address);
// Save workbook to file
FileOutputStream outputStream = new FileOutputStream("data.xlsx");
workbook.write(outputStream);
outputStream.close();
// Print file
PrintRequestAttributeSet printAttributes = new HashPrintRequestAttributeSet();
PrintService[] printServices = PrintServiceLookup.lookupPrintServices(null, printAttributes);
if (printServices.length > 0) {
DocPrintJob printJob = printServices[0].createPrintJob();
FileInputStream inputStream = new FileInputStream("data.xlsx");
Doc doc = new SimpleDoc(inputStream, DocFlavor.INPUT_STREAM.AUTOSENSE, null);
printJob.print(doc, printAttributes);
inputStream.close();
}Note that you will need to add error handling to this code to handle exceptions that may occur during file I/O or printing.

public class TestFrame extends JFrame {

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(400, 200);

// Save workbook to file

lastNameField.setText("");
} catch (Exception ex) {
ex.printStackTrace();
}
}
});
panel.add(firstNameField);
panel.add(middleNameField);
panel.add(lastNameField);
panel.add(enterButton);
add(panel);
setVisible(true);
}
public static void main(String[] args) {

To calculate the age from the date entered in a JTextField, you can use thehow to automatically calculate age by the date input from the JFrame Form after clicking enter.
java.time package introduced in Java 8. Here's an example code snippet that demonstrates how to calculate age in years:
Code:
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.text.ParseException;
import java.time.LocalDate;
import java.time.Period;
import java.time.format.DateTimeFormatter;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
public class TestFrame extends JFrame {
private JTextField firstNameField, middleNameField, lastNameField, dobField;
public TestFrame() {
super("Test Frame");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(400, 200);
setLocationRelativeTo(null);
JPanel panel = new JPanel();
firstNameField = new JTextField(20);
middleNameField = new JTextField(20);
lastNameField = new JTextField(20);
dobField = new JTextField(20);
JButton enterButton = new JButton("Enter");
enterButton.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
try {
// Parse date of birth from text field
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MM/dd/yyyy");
LocalDate dob = LocalDate.parse(dobField.getText(), formatter);
// Calculate age in years
LocalDate now = LocalDate.now();
int age = Period.between(dob, now).getYears();
// Do something with the age
System.out.println("Age: " + age);
} catch (ParseException ex) {
ex.printStackTrace();
}
}
});
panel.add(firstNameField);
panel.add(middleNameField);
panel.add(lastNameField);
panel.add(dobField);
panel.add(enterButton);
add(panel);
setVisible(true);
}
public static void main(String[] args) {
new TestFrame();
}
}In this example, the date of birth is parsed from a JTextField using a
DateTimeFormatter, and then the Period.between() method is used to calculate the difference between the birth date and the current date. Finally, the getYears() method is called on the Period object to obtain the age in years. You can then do something with the age as needed.Similar threads
