How to create JButton array?

Question

I have used below code but did not work properly. I have list of JButton objects on the panel but could not click on each button individually.

for(int i=0; i<udataArr.length(); i++) {
    userBtn = new JButton();
    userLb = new JLabel();

    cur1 = userBtn.getCursor();
    userBtn.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));

    Image imgUO =  ImageIO.read(getClass().getResource("/resources/img-std.png"));
    userBtn.setIcon(new ImageIcon(imgUO));
    userBtn.setBorder(BorderFactory.createCompoundBorder(border,paddingBorder));
    userLb.setText((String) udataArr.getJSONObject(i).get("user_name"));
    //button[i].setText((String) udataArr.getJSONObject(i).get("user_name"));
    panelLeft.add(userBtn);
    panelLeft.add(userLb);
    panelLeft.add(Box.createVerticalStrut(15));
}

enter image description here

"did not work properly" doesn't really describe the issue. There's also no indication that you've got an array of JButtons anywhere... did you mean to declare a JButton[] buttons variable somewhere? — Jon Skeet

JButton[] myArray = new JButton[]{new JButton("first"), new JButton("second")}; — Leo Pflug

For better help sooner, post an MCVE (Minimal Complete and Verifiable Example). Note that one component can be added to a maximum of one container exactly one time. — Andrew Thompson

This is the code to create JButton Array

JButton buttons[];
buttons = new JButton[10];
for(int i = 0; i < 10; i++) {
    buttons[i] = new JButton(String.valueOf(i));
}
