I have six JTextFields on JPanel and I need to verify all inputs in JTextFields.
Depend on validation of inputs, my program need generate JOptionPane.showMessageDialog. However, there so many different cases, and I can't write JOptionPane.showMessageDialog for each different case.
My qustion is how do I get all different dialog message by using only one JOptionPane.showMessageDialog statement?

For example, if a user didn't put anything and just press 'verify' button, JOptionPane.showMessageDialog should show all six different mssages. If a user put  threee valid inputs, then three messages for invalid input should be on JOptionPane.

String lineSeparator = System.getProperty("line.separator");
StringBuffer message = new StringBuffer();
message.append("message 1");
message.append("message 2");
message.append("message 6");

showMessageDialog(parentComponent, message, title, messageType);

This way, you can show all the messages in one message box.

>> showMessageDialog(parentComponent, message, title, messageType);


showMessageDialog ( parentComponent, message.toString (), title, messageType ) ;
