Question

Is there any way to accept only numeric values in a JTextField? Is there any special method for this?

Answer 1

Use formatter to format text field.

NumberFormat format = NumberFormat.getInstance();
format.setGroupingUsed(false);
NumberFormatter formatter = new NumberFormatter(format);
formatter.setValueClass(Integer.class);
formatter.setMaximum(65535);
formatter.setAllowsInvalid(false);
formatter.setCommitsOnValidEdit(true);
myTextField = new JFormattedTextField(formatter);
