To set the alignment of the label’s content along the Y axis on the top, use the setVerticalAlignment() method and set the location. Let us first set a label component. We have set the label background color as well so that we can check the alignment of the label’s content properly −JLabel label = new JLabel("Favourite Movie"); label.setPreferredSize(new Dimension(190, 100)); label.setOpaque(true); label.setBackground(Color.GREEN); label.setForeground(Color.WHITE);Now, we will align the label content along the Y axis on the top by seeting location as TOP −label.setVerticalAlignment(JLabel.TOP);The following is an example to set the alignment of the JLabel content along the Y axis on the ...
