Thread: Displaying things in gui

Hello.

I was wandering how to display a content of an ArrayList in a GUI??

I tried to do this in this way:

for(int i = 0;i<student.size(); i++){
 
			JOptionPane.showMessageDialog(null, student.get(i).getName()
				   + " " + student.get(i).getSurname()
				   + " " + student.get(i).getGradesString()
				   + "\n");
		}

but it did not work and it was displaying dialog box one after another.
What i would like is to display all this informations all at once in one window.

Could anyone give me some tips on how to do this??

Regards

A JTable is probably what you want. Look at How to Use Tables (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components)

you could add the arraylist's content to a string and use JOptionPane to show your string
