Store contents from JTable into a text file.

[Sherly Changappa]

Hello ,
I have written a swings form with 5 text boxes and a button. When i click the button save, the data entered is being displayed in the table. Now i want to store the data shown in the table into a text file. Can anyone please help me with this code. I am still a java beginner and have very less idea about java coding. After lot of surfing, i was able to do the table part. I am attaching the code done so far. Please excuse if i have done some silly mistakes. Really in need of your help. Thanks in advance..

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

class ReadTextFile extends JFrame
{
JButton save;
JPanel panel;
JLabel label1,label2,label3,label4,label5;
final JTextField text1,text2,text3,text4,text5;

ReadTextFile(){
label1 = new JLabel();
label1.setText("English Word:");
text1 = new JTextField(20);

label2 = new JLabel();
label2.setText("English Synonym:");
text2 = new JTextField(20);

label3 = new JLabel();
label3.setText("Kannada Word:");
text3 = new JTextField(20);

label4 = new JLabel();
label4.setText("Kannada Synonym:");
text4 = new JTextField(20);

label5 = new JLabel();
label5.setText("Parts of Speech:");
text5 = new JTextField(20);

save=new JButton("SAVE");

panel=new JPanel(new GridLayout(6,2));
panel.add(label1);
panel.add(text1);
panel.add(label2);
panel.add(text2);
panel.add(label3);
panel.add(text3);
panel.add(label4);
panel.add(text4);
panel.add(label5);
panel.add(text5);
panel.add(save);
add(panel,BorderLayout.CENTER);
setTitle("Word Base");

save.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae){
String value1=text1.getText();
String value2=text2.getText();
String value3=text3.getText();
String value4=text4.getText();
String value5=text5.getText();
Object rowData[][] = { { value1, value2,value3,value4, value5} };
Object columnNames[] = { "English Word", "English Synonym", "Kannada Word","Kannada Synonym","POS" };
JFrame f=new JFrame();
JTable table = new JTable(rowData,columnNames);
JScrollPane scrollPane = new JScrollPane(table);
JPanel p=new JPanel();
p.add(scrollPane);
f.add(p);
f.setVisible(true);
//f.setDefaultLookAndFeelDecorated(true);
f.setSize(400,200);
}
});
}


public static void main(String arg[])
{
try
{
ReadTextFile frame=new ReadTextFile();
frame.setSize(300,200);
frame.setVisible(true);
}
catch(Exception e)
{}
}
}

Could you please post your code inside code tags. It would be easier us to read. Now coming to your question, you could have a function like this to store the contents in file.

private void writeToFile(Object[] colHead,Object[][] rowData){
    try{
          //create an output stream to store in file
          //write the contents passed as parameter to this function
          
    }
    catch(Exception e){}
}

You can call the above function once you assign the data to the table.

Thank you sir. Your help is greatly appreciated. I'm sorry for the inconvenience made. I'm new to this forum and so dint know the format of posting. Will keep that in mind next time.
Can you please give me a sample snippet of the code you just mentioned. Finding hard to understand so.

He did, but didn’t use them correctly. Unfortunately when I corrected the code tags, it simply highlighted the lack of indentation.

You didn’t comment on the empty catch block. Nor on trying to catch an Exception as opposed to a specific type of Exception. Nor on catching Exception when it was not declared in a throws clause.
