Hello all, this is my first post im pretty new to java, cant get String.format to work properly, it tells me that the String is not applicable for the arguments(string, double)...any thoughts?

 class CFListen implements ActionListener{
        public void actionPerformed(ActionEvent event){
            TempConversion convert = new TempConversion(Double.parseDouble(userInput.getText()) );
            theOutput.setText("C to F : " + String.format("%.2f",convert.CtoF()));
        }
    }

Is there something else i can use other than String.format to display 3 digits after the decimal point?

The DecimalFormat class will do the job

but what's wrong with String.format() ?
If you want 3 digits you will need %.3f not %.2f and are you sure convert.CtoF() returns a float/double ?

That was the problem, it wasn't returning a float/double. Thanks for the help
