Loading my text file into my jtable
Ok i was able to figure out how to save the data in my jtable as text file but im not sure how i suppose to load it.
I've been trying to figure this out for few day now and i still lost on how to go about it.
this is the code I have for saving my jtable
when i save my code the output in the text file look like this:
First Name: dan
Last Name: ram
Phone Number: (342) 423-4324
Email: email@live.com
Code:
savecontact.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
JFileChooser filesave = new JFileChooser();
FileNameExtensionFilter filter = new FileNameExtensionFilter("TEXT File", ".txt", "text");
filesave.setFileFilter(filter);
int returnVal = filesave.showSaveDialog(Main.this);
if (returnVal == JFileChooser.APPROVE_OPTION) {
try {
File file = filesave.getSelectedFile();
PrintWriter os = new PrintWriter(file +".txt");
for (int row = 0; row < table.getRowCount(); row++) {
for (int col = 0; col < table.getColumnCount(); col++) {
os.print(table.getColumnName(col));
os.print(": ");
os.println(table.getValueAt(row, col));
}
}
os.close();
System.out.println("Done!");
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
}
});
this is my table
Code:
table.setModel(new DefaultTableModel(
new Object[][] {
},
new String[] {
"First Name", "Last Name", "Phone Number", "Email"
}
));
