Java - Display A List Of Files Name From Folder To JTable

Java JTable Code - Populate A Jtable With A List Of Files Names From A Folder In Java Using NetBeans .

In this java Tutorial we will see How To Populate A JTable With Files Names From A Folder In Java Using NetBeans .

*Java Courses : Java Complete Course

Java Swing Course

- to do that we will create a function and call it "getFilesName" :

public void getFilesName()

{

File file = new File(getClass().getResource("/java_tutorials/products").getFile());

File[] files = file.listFiles();

DefaultTableModel model = (DefaultTableModel)jTable_Files_Name.getModel();

model.setColumnIdentifiers(new String[]{"Files Names"});

Object[] row = new Object[1];

for(int i = 0; i < files.length; i++)

{

row[0] = files[i].getName();

model.addRow(row);

}

Entire Project Source Code:

package JAVA_VIDEOS_TUTORIALS;

import java.io.File;
import javax.swing.table.DefaultTableModel;

/**

public class JTable_Files_Name extends javax.swing.JFrame {

/**
* Creates new form JTable_Files_Name
*/
public JTable_Files_Name() {
initComponents();
// call the function
getFilesName();
}

public void getFilesName()
{
File file = new File(getClass().getResource("/java_tutorials/products").getFile());

File[] files = file.listFiles();

DefaultTableModel model = (DefaultTableModel)jTable_Files_Name.getModel();

model.setColumnIdentifiers(new String[]{"Files Names"});

Object[] row = new Object[1];

for(int i = 0; i < files.length; i++)
{

row[0] = files[i].getName();

model.addRow(row);

}
}
