This example in java shows how to mail using java mail service to sent a mail. User need to create a gmail account). Automatic mail sending application using google spreadsheet (google script)

Java SMTP Mail Sent Application

if you are getting an error : authentication failed, or gmail blocked login attempt, then you should enable the access for less secure apps in your account

Some devices and apps use insecure sign-in technology to access your data.
Choosing Disable prevents these less secure devices and apps from accessing your Google Account.
Choosing Enable increases your chances of unauthorized account access but allows you to continue using these less secure devices and apps. Learn more

Access for less secure apps should be enabled

Example show how to create a text field in java swing that accepts only numbers

initializing variable


private JFormattedTextField expAmount_txt = null;

adding to container


panel.add(getExpAmount_txt(),null);
private JFormattedTextField getExpAmount_txt() {
if (expAmount_txt == null) {
Format general = NumberFormat.getInstance();
expAmount_txt = new JFormattedTextField(general);
expAmount_txt.setBounds(new Rectangle(120, 40, 120, 20));
expAmount_txt.setHorizontalAlignment(JFormattedTextField.RIGHT);
}
return expAmount_txt;
}

retrieving value


Double.parseDouble(expAmount_txt.getValue().toString());
