Make A Simple Java Table Program (With Example Code)

After publishing my previous post How To Make a Calculator In Java With Source Code. I am now here for you to teach a new updated post is making a simple java table program. By following this post you will get an extraordinary table from others. Just follow and trying to do.

So, let’s see, How to Create a Simple Table a step-by-step guide that makes with this example code below.

Java Code Make Table Program 

The java codes appear below;

//Imports are listed in full to show what’s being used

//could just import javax.swing.* and java.awt.* etc..

import java.awt.Color;

import java.awt.EventQueue;

import javax.swing.JFrame;

import javax.swing.JTable;

import javax.swing.JScrollPane;

import javax.swing.JComboBox;

import javax.swing.table.AbstractTableModel;

import javax.swing.table.TableColumn;

import javax.swing.DefaultCellEditor;

public class TableExample {

    //Note: Typically the main method will be in a

    //separate class. As this is a simple one class

    //example it’s all in the one class.

    public static void main(String[] args) {

     

         //Use the event dispatch thread for Swing components

         EventQueue.invokeLater(new Runnable()

         {

             

            @Override

             public void run()

             {

                 

                 new TableExample();         

             }

         });

              

    }

    

    public TableExample()

    {

        JFrame guiFrame = new JFrame();

        

        //make sure the program exits when the frame closes

        guiFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        guiFrame.setTitle(“Creating a Table Example”);

        guiFrame.setSize(700,200);

      

        //This will center the JFrame in the middle of the screen

        guiFrame.setLocationRelativeTo(null);

        

        //Create the JTable using the ExampleTableModel implementing 

        //the AbstractTableModel abstract class

        JTable table = new JTable(new ExampleTableModel());

        

        //Set the column sorting functionality on

        table.setAutoCreateRowSorter(true);

        

        //Uncomment the next line if you want to turn the grid lines off

      //  table.setShowGrid(false);

        

        //Change the colour of the table – yellow for gridlines 

        //blue for background

        table.setGridColor(Color.YELLOW);

        table.setBackground(Color.CYAN);

        

        //String array to populate the combobox options

        String[] countries = {“Australia”, “Brazil”, “Canada”, “China”

                    ,”France”, “Japan”, “Norway”, “Russia”, “South Korea”

                    , “Tunisia”, “USA”};

        JComboBox countryCombo = new JComboBox(countries);

       

        //Set the default editor for the Country column to be the combobox

        TableColumn countryColumn = table.getColumnModel().getColumn(2);

        countryColumn.setCellEditor(new DefaultCellEditor(countryCombo));

       

        //set the Event column to be larger than the rest and the Place column 

        //to be smaller

        TableColumn eventColumn = table.getColumnModel().getColumn(3);

        eventColumn.setPreferredWidth(150);

        

        TableColumn placeColumn = table.getColumnModel().getColumn(4);

        placeColumn.setPreferredWidth(5);

        

        //Place the JTable object in a JScrollPane for a scrolling table

        JScrollPane tableScrollPane = new JScrollPane(table);

        

        guiFrame.add(tableScrollPane);

        guiFrame.setVisible(true);

    }

    

    //implement a table model by extending a class to use

    //the AbstractTableModel

    class ExampleTableModel extends AbstractTableModel{

        

        //Two arrays used for the table data

        String[] columnNames = {“First Name”, “Surname”, “Country”

                        , “Event”, “Place”, “Time”, “World Record” };

These are the codes for making a simple java table program. Just use it for making the table. Have any problem or question? Ask me via the comment section. I will try to answering as soon as possible. If this post is helpful to share it with your buddies in social media.
