Replace File Confirmation fow swing

[g666]

Its not much, but i found it a bit strange that swing didnt already do this so i made a subclass of jfilechooser that asks the user if they want to replace the file when selecting to save an existing file.

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20   21   22   23   24   25   26

import java.awt.*; import javax.swing.*; import java.io.*; /**  *a filechooser that checks the user wants to when returning an existing filename  */   public class CheckFileChooser extends JFileChooser{        public void approveSelection(){       if(getDialogType() == SAVE_DIALOG){          File sel = getSelectedFile();          if(sel.exists()){             int ow = JOptionPane.showConfirmDialog(this,                "The file "+sel.getName()+" already exists, do you want to replace it?",                "Replace File?",                JOptionPane.WARNING_MESSAGE);             //user clicked cancel?            if(ow != 0)                return;          }       }       super.approveSelection();    } }
