    Default Storing radiobutton into file

    ive been working on this for a while and have tried several alternatives and its getting late heh. I am having problems taking a radiobutton, and storing it as a string in a .csv file.

    try{
    		if(btn1.isSelected())
    		{
    			gender = "Male";
    		}
    		if(btn2.isSelected())
    		{
    			gender = "Female";
    		}
    	FileWriter writer = new FileWriter("Student.csv");
     
     
     
    	writer.write(lbl1 + ", " + txt1.getText());	    
    	writer.write('\n');
    	writer.write(lbl1 + ", ");
     
    	writer.write('\n');
    	[B][U]writer.write(lbl3 + gender);[/U][/B]
    	    writer.write('\n');
     
    	    writer.write(lbl2 + ", " + txt2.getText());
     
    	writer.close();
     
    	} catch (Exception e){
     
    	System.err.println("Error: " + e.getMessage());
     
    	}
    The main line i am interested in is the one underlined, every time i try to save it into a .csv file i get an error "null"

    this is the other way i tried.


    String choice = group.getSelection().getActionCommand();
    try{
     
    FileWriter writer = new FileWriter("Student.csv");
     
     
     
    writer.write(lbl1 + ", " + txt1.getText());	    
     
        writer.write('\n');
     
        [B][U]writer.write(lbl7 + ", " + choice);[/U][/B]
     
        writer.write('\n');
     
        writer.write(lbl2 + ", " + txt2.getText());
     
    writer.close();
     
    } catch (Exception e){
     
    System.err.println("Error: " + e.getMessage());
     
    }

    ignore all the other rubbish around it

    Default Re: Storing radiobutton into file

    I presume you mean JRadioButton? How do you wish to 'save' this? By the string that defines the Label? Passing the object will cause it to use the Object's toString method...if the results you see are null it means the Object you passed is null. If this makes no sense, I recommend posting something more complete and compilable (eg an SSCCE) to demonstrate the problem that will provide more context to the problem.
