Making a String accept only letters ( no numbers ).
java, jtextfield, netbeans-7, string, swing
Solution
you have two choices to use
JFormattedTextField with proper `Formatter` or `InputVerifier`
use DocumentFilter
- notice don't use `String Text;` (possible reserved word for API name or its method) use `String text;` more in the Naming convention
Problem
Is it possible to allow only letters or numbers in a string in java ? for example : ``` String Text; Text = jTextField1.getText(); ``` now ``` if (Text is a number) {System.out.println("Invalid Input");} ```
