Creating Many Panels

Question

Hello. I am greating a GPA. There is a credits JComboBox and a grade JComboBox. I created a method to create a JPanel which includes both of these.
public JPanel createGradePanel() {
JPanel gradePanel = new JPanel();
gradePanel.setBackground(Color.LIGHT_GRAY);
gradePanel.setLayout(new BoxLayout(gradePanel, BoxLayout.X_AXIS));
JLabel creditsLabel = new JLabel("Credits:");
JLabel gradeLabel = new JLabel("Grade:");
JComboBox gradeCombo = new JComboBox();
JComboBox creditsCombo = new JComboBox();
gradeCombo.addItem("");
gradeCombo.addItem("A");
gradeCombo.addItem("A-");
gradeCombo.addItem("B+");
gradeCombo.addItem("B");
gradeCombo.addItem("B-");
gradeCombo.addItem("C+");
gradeCombo.addItem("C");
gradeCombo.addItem("C-");
gradeCombo.addItem("D+");
gradeCombo.addItem("D");
gradeCombo.addItem("D-");
gradeCombo.addItem("E");
creditsCombo.addItem("");
creditsCombo.addItem("1");
creditsCombo.addItem("2");
creditsCombo.addItem("3");
creditsCombo.addItem("4");
creditsCombo.addItem("5");
creditsCombo.addItem("6");
gradePanel.add(Box.createHorizontalStrut(88));
gradePanel.add(creditsLabel);
gradePanel.add(Box.createHorizontalStrut(6));
gradePanel.add(creditsCombo);
gradePanel.add(Box.createHorizontalStrut(6));
gradePanel.add(gradeLabel);
gradePanel.add(Box.createHorizontalStrut(6));
gradePanel.add(gradeCombo);
gradePanel.add(Box.createHorizontalStrut(50));
return gradePanel;
Now, in my construcor I add this panel to another panel.
for(int i=0;i<7;i++){
infoPanel.add(createGradePanel());
The only problem is that all of my comboboxes are named the same, so I can't the selected item of a specific one. Is there any way to do this where I can give them a specific name, ie gradeCombo1, gradeCombo2 without actually creating each panel speratly?

You could create arrays of JComboBoxes and reference them by index.
