JPanel myPanel = new JPanel(); myPanel.setMaximumSize(new Dimension(200, 300));
JPanel myPanel = new JPanel(); myPanel.setMaximumSize(new Dimension(Integer.MAX_VALUE, Integer.MAX_VALUE));In this example, we set the maximum size of the panel to the maximum possible value for width and height. This allows the panel to grow infinitely, filling up all available space. Both examples use the setMaximumSize method of the JPanel class in the java.awt.event package library to set the maximum size of a JPanel.
