Set the value to JtextField in Jtable : JAVA

Question

I try to set default path and set this value to JtextField. When I add new row and select the path it works. But when the script is first start, I try to give default path to first row but it doesn't take the correct string.

This is the screenshot : I give the path -> //bie-pvcs-01/logs_122 but it takes role_script.MainGuiComp@127077b

Here is my code :

public class MainGui extends JFrame {

private JPanel contentPane;

private JComboBox<String> comboBox;
private JLabel pathWarningLabel;
private ArrayList<String> plist = new ArrayList<>();
File lastDirectory = new File(File.separator+File.separator+"bie-pvcs-01"+File.separator+"logs_122"+File.separator);
private JTextField textField;
private JTable table;

Answer 1

Seems you store values in JTabel like your own objects( Comp ). Try to replace in your btnNewButton ActionListener method next lines:

 for(int i=0; i<CompTable.getRowCount(); i++){
       if(CompTable.getValueAt(i, 0).toString() != null && !CompTable.getValueAt(i, 0).toString().equals("")){
             plist.add(CompTable.getValueAt(i,0).toString());
       }
 }

by that:

   for(int i=0; i<CompTable.getRowCount(); i++){
         String value = ((Comp)CompTable.getValueAt(i, 0)).lower;
         if(value!= null && !value.isEmpty()){
               plist.add(value);
         }
   }

it helps you. Because when you use getValueAt() method you get Comp instance, you can cast it and get value from that object.

Also read about name convention .
