getting the value of variable

[Lehane_9]

public void actionPerformed(ActionEvent e)
{

if (!txtBox.getText().equals("")){
int a = 0;

for(int i = 0; i < combo.getItemCount(); i++){
if(combo.getItemAt(i).equals(txtBox.getText())){
a = 1;
break;
}
}
if (a == 1)
JOptionPane.showMessageDialog(null,"Combo has already this item.");

else

combo.addItem(txtBox.getText());

// I want to store the value of txtBox.text(), to an array and then to a file,
if some could show me how to do this it would be appreciated as i have tried for about an hour and a half myself.
thank you in advance!!

Well, what do you about arrays, and FileWriting?

If you don't know how to use arrays, you should learn how. And, you will need to learn about the FileWriter class. (Or BufferedWriter, or PrintWriter).

Just let us know what you know so we can assist you.

You'll probably want an array list since you don't know how many items you'll be getting.

Quote:

import java.util.ArrayList; // import
ArrayList<String> items = new ArrayList<String>(); // how to declare one

and then each time you find a new item and add it to the combo just add this line with it:

Quote:

items.add(txtBox.getText());

As for writing it to a file, that's kind of complicated...
