Thread: Check if 'int' is empty

Hi, I'm new to Java programing started learning it today. And have a bit of a problem.

Then clicking button program converting Celsius to Fahrenheit and vice versa.
I need to check 'CelsijusTextField' if it's not empty then program converting Celsius to Fahrenheit and
if 'FarenheitasTextField' is not empty program converts Fahrenheit to Celsius.

        int Celsijus = (int)((Double.parseDouble(CelsijusTextField.getText())));
        int Farenheitas = (int)((Double.parseDouble(FarenheitasTextField.getText())));
        if (Celsijus != 0) {
            FarenheitasTextField.setText(Celsijus * 1.8 + 32 + "");
        } else if (Farenheitas != 0) {
            CelsijusTextField.setText((Farenheitas - 32 / 1.8) + "");
        }

Hello TrYk!

I need to check 'CelsijusTextField' if it's not empty then program converting Celsius to Fahrenheit and
if 'FarenheitasTextField' is not empty program converts Fahrenheit to Celsius.

A way to do this is with the isEmpty() method of the String class.
String (Java Platform SE 7 )
