Numeric-Validator

Validate numeric input (int or double) for Java GUI (Swing and JavaFX)

Usage

Gradle

import the project from maven as follow:

compile 'com.github.jlarrieux:numeric-validator:1.+'

Maven

<dependency>
   <groupId>com.github.jlarrieux</groupId>
   <artifactId>numeric-validator</artifactId>
   <version>1.0.2</version>
</dependency>

Example

Java Swing

NumericValidator validator = new NumericValidator(NumericValidator.TypeOfNumber.DOUBLE);
boolean result = validator.validate(textField);

Java FX

For JavaFX, you must add the RedBorder.css to your project and call the code as follow

dialogStage.getScene().getStylesheets().add(getClass().getResource("/css/RedBorder.css").toExternalForm());
NumericValidator val = new NumericValidator(NumericValidator.TypeOfNumber.INTEGER);
boolean result = validator.validate(textField);

If you don't have the css, it won't highlight the appropriate input in red.
