Hello Java Forum,

Ola Norm, I am more of weekend programmer, since I have job, duties,... but no kids yet, so I can use weekends for 'programming'

I have made my application with Visual C#, please take a look at www beezgetz.com/Tour.aspx . Now I want to translate it to java, so Mac users can use it.

Here is the picture of my java application, where jTextField checks each typed 'character' of string (as it is typed) if it is really a number (double), and if it is not, to clear the jTextField.

Here is code

Code:

private void DoubleTextFieldCaretUpdate(javax.swing.event.CaretEvent evt) {
	
     try { 
        String number = DoubleTextField.getText();  // I get string from TextField
        DecimalSeparator.StringToDouble(number);    // I run it through DecimalSeparatot Class to make it double, or catch (Exception e).
        DoubleLabel.setText(String.valueOf(number) + " double");   //I run some action
        
    }
    catch (Exception e) {
        DoubleTextField.setText("");
    } 
    
    
}

Here is called Class:

Code:

public class DecimalSeparator {
 public static double StringToDouble(String stringNum) {
             
            String decimalCharacter = "."; 
            stringNum = stringNum.replace(".", decimalCharacter);
            stringNum = stringNum.replace(",", decimalCharacter);
           
                return Double.parseDouble(stringNum);
         
            
        }
}

I am getting familiar with api, but I need some time to make it search the 'right stuff'


Kind regards, Grom
