Java And MySQL - How To Display Image From Mysql Database To JTable In Java NetBeans

How To Populate JTable Depending On JCombobox Selected Value In Java NetBeans

In this java Tutorial we will see How To Fill data Into JTable from Mysql  database And Also Displaying Picture From Mysql Database In Java NetBeans .

// Step 1 Create A Class Named "Product2"

package javaapp;

public class Product2 {

    private String id;
    private String name;
    private int qte;
    private String price;
    private int catId;
    private byte[] Image;
    
    public Product2(){}
    
    public Product2(String Id, String Name, int Qte, String Price,byte[] image, int CatId){
    
        this.id = Id;
        this.name = Name;
        this.qte = Qte;
        this.price = Price;
        this.Image = image;
        this.catId = CatId;
       
    }
    
    
    public String getID(){
      return id;
    }
    
    public void setID(String ID){
        this.id = ID;
    }
    
    public String getName(){
        return name;
    }
    
    public void setName(String Name){
        this.name = Name;
    }
    
    public int getQte(){
        return qte;
    }
    
    public void setQte(int Qte){
        this.qte = Qte;
    }
    
    public String getPrice(){
        return price;
    }
    
    public void setPrice(String Price){
        this.price = Price;
    }
    
    public int getCatID(){
        return catId;
    }
    
    public void setCatID(int CatID){
        this.catId = CatID;
    }
    
    public byte[] getMyImage(){
        return Image;
    }
}

// Step 2 Create A Class Named "MyQuery"

package javaapp;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.logging.Level;

import java.util.logging.Logger;

/**

public class MyQuery {

    

   public Connection getConnection(){

        Connection con = null;

        try {

            con = DriverManager.getConnection("jdbc:mysql://localhost/project", "root","");

        } catch (SQLException ex) {

            Logger.getLogger(Query.class.getName()).log(Level.SEVERE, null, ex);

        }

        return con;

    }

    

    public ArrayList<Product2> BindTable(){
        
   ArrayList<Product2> list = new ArrayList<Product2>();
   Connection con = getConnection();
   Statement st;
   ResultSet rs;
   
   try {
   st = con.createStatement();
   rs = st.executeQuery("SELECT `ID_PRO`, `PRO_NAME`, `QTE_IN_STOCK`, `PRICE`, `PRO_IMAGE`, `ID_CAT` FROM `products`");
   
   Product2 p;
   while(rs.next()){
   p = new Product2(
   rs.getString("ID_PRO"),
   rs.getString("PRO_NAME"),
   rs.getInt("QTE_IN_STOCK"),
   rs.getString("PRICE"),
   rs.getBytes("PRO_IMAGE"),
   rs.getInt("ID_CAT")
   );
   list.add(p);
   }
   
   } catch (SQLException ex) {
   Logger.getLogger(MyQuery.class.getName()).log(Level.SEVERE, null, ex);
   }
   return list;
   }
}

// Step 3 Create A Class Named "TheModel"

package javaapp;

import javax.swing.Icon;
import javax.swing.table.AbstractTableModel;

/**

 * @author 1bestcsharp.blogspot.com

 */

public class TheModel extends AbstractTableModel {

    private String[] columns;
    private Object[][] rows;
    
    public TheModel(){}
    
    public TheModel(Object[][] data, String[] columnName){
    
        this.rows = data;
        this.columns = columnName;
    }

    
    public Class getColumnClass(int column){
// 4 is the index of the column image
        if(column == 4){
            return Icon.class;
        }
        else{
            return getValueAt(0,column).getClass();
        }
    }
    
    
    public int getRowCount() {
     return this.rows.length;
    }

    public int getColumnCount() {
     return this.columns.length;
    }

    
    public Object getValueAt(int rowIndex, int columnIndex) {
    
    return this.rows[rowIndex][columnIndex];
    }
    public String getColumnName(int col){
        return this.columns[col];
    }


}

// Step 4 Create A JFrame Named "JTableWithImage"

package javaapp;

import java.awt.Image;
import java.util.ArrayList;
import javax.swing.ImageIcon;

/**

public class JTableWithImage extends javax.swing.JFrame {

    public JTableWithImage() {
        initComponents();
        populateJTable();
    }

  // create a methode to populate data Into JTable from Mysql  database And Displaying Picture
    
    public void populateJTable(){
        MyQuery mq = new MyQuery();
        ArrayList<Product2> list = mq.BindTable();
        String[] columnName = {"Id","Name","Qte","Price","Image","Categorie"};
        Object[][] rows = new Object[list.size()][6];
        for(int i = 0; i < list.size(); i++){
            rows[i][0] = list.get(i).getID();
            rows[i][1] = list.get(i).getName();
            rows[i][2] = list.get(i).getQte();
            rows[i][3] = list.get(i).getPrice();
            
            if(list.get(i).getMyImage() != null){
                
             ImageIcon image = new ImageIcon(new ImageIcon(list.get(i).getMyImage()).getImage()
             .getScaledInstance(150, 120, Image.SCALE_SMOOTH) );   
                
            rows[i][4] = image;
            }
            else{
                rows[i][4] = null;
            }
            rows[i][5] = list.get(i).getCatID();
        }
        
        TheModel model = new TheModel(rows, columnName);
        jTable1.setModel(model);
