Centering a JLabel Horizontally in a JPanel Using NetBeans GUI Builder

In the NetBeans GUI Builder, centering a JLabel in a JPanel is achievable by utilizing one of the following methods:

Border Layout: Create a sub-panel using the BorderLayout layout manager and add the label to the CENTER position, ensuring it remains centered regardless of panel resizing.
GridBagLayout: Add the label to a GridBagLayout, using a column weight of 0 and fill set to GridBagConstraints.BOTH, which naturally centers the label within the JPanel.
GridLayout: Create a sub-panel with a single cell GridLayout and add the label to it. This method aligns the label to the center of the JPanel, but it doesn't maintain centering upon resizing.
BoxLayout with Horizontal Glue: Use a BoxLayout with X_AXIS alignment for the sub-panel. Add two Box.createHorizontalGlue() components on either side of the label to force it to the center. This ensures centering even during resizing.
