Most simple code to populate JTable from ResultSet

Question

I googled the whole day and no luck. I call getnPrintAllData() method after pressing OK button. So the code is:

public class DatabaseSQLiteConne         


        

Answer 1

The JTable constructor accepts two arguments 2dimension Object Array for the data, and String Array for the column names.

eg:

import java.awt.BorderLayout;
import java.awt.Color;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;

public class Test6 extends JFrame {

    public Test6(){     
        this.setSize(300,300);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Mpanel m = new Mpanel();
        this.add(m,BorderLayout.CENTER);        
    }


    class Mpanel extends JPanel {       

        JTable mTable;
        private Object[][] cells = {{"Vivek",10.00},{"Vishal",20.00}};
        private String[] columnNames = { "Planet", "Radius" };
        JScrollPane mScroll;

        public Mpanel(){
            this.setSize(150,150);
            this.setComponent();
        }

        public void setComponent(){
            mTable = new JTable(cells,columnNames);
            mTable.setAutoCreateRowSorter(true);
            mScroll = new JScrollPane(mTable);

            this.add(mScroll);
        }
    }

    public static void main(String[] args){     
        new Test6().setVisible(true);
    }
}
