Regular expression in java for validating numbers

Integer Validator validator = new Integer Validator(true, Integer Validator.

CURRENCY_FORMAT); String pattern = "#,###" '\u00A4' '\u00A4'; // Use international symbol Integer foo Amount = validator.validate("10.100EUR", pattern, Locale.

US); if (foo Amount == null) // Check the amount is a minimum of $1,000 if (Value(foo Amount, 1000) If, for example, you want to use the Integer Validator to validate a currency, then you can simply create a new instance with the appropriate format style.

Note that the other validators do not support the lenient currency symbol validation.

Please note the format is specified using the standard symbols for // Get the Integer validator Integer Validator validator = Integer Instance(); // Validate/Convert the number Integer foo Integer = validator.validate(foo String, "#,##0.00", Locale.

GERMAN); if (foo Integer == null) Formatting and validating are two sides of the same coin.

They are typically configured by web-developers (but we provide some samples below).

Below are some helpful resources: Wikipedia page on regular expressions: A java reference for regular expressions: online testing tool for java-based (regex) regular expressions: can be difficult to determine what a regular expression does just by looking at it.

Therefore we added another field where you can write a description of the validation being performed by your regular expression.

Keep in mind that this description will be visible by your lead Sellers so make your description detailed enough so that it is easy to understand.
