API Method to check if value in a string variable is positive numeric value
I have a String variable in java,
String strNum = "-90.29";
Apart from regex, is there any API method available to check if strNum contains a valid positive decimal value.
Can anyone please help?

You can use the Apaches commons.lang.math like (null-safe):
NumberUtils.toScaledBigDecimal(strNum).signum() == 1
