isNum

[DrGenious]

Hi,

I am trying to parse a file and I wrote in tjavarow component this line( boolean numeric = isNumeric(input_row.Cell_Name); ) but it idoesnt run.

How can I convert this expression into order to see if it is numeric and store it into a variable? 

Thanks a lot.

@DrGenious , you need to use something like below code.

public static boolean isNumeric(String strNum) {

    if (strNum == null) {

        return false;

    }

    try {

        double d = Double.parseDouble(strNum);

    } catch (NumberFormatException nfe) {

        return false;

    }

    return true;

}

@manodwhb  Is not any simplier way? I dont want to declare it as a double , I want only to take the boolean result.

@DrGenious , you need to write specified java otherwise not sure.

Talend has a routine Mathematical.NUM(input) that returns 1 if it's a numeric data type and 0 if not. Would that work?
