The java javax.swing JCheckBox setOpaque method is used to change the opacity of a checkbox. The setOpaque method takes a boolean input parameter that specifies whether the checkbox should be opaque or not.
Example 1:
JCheckBox checkBox = new JCheckBox("Option1"); checkBox.setOpaque(false);
In this example, the JCheckBox component with the label "Option1" is created and the setOpaque method is called with a value of false to make the checkbox transparent.
Example 2:
JCheckBox checkBox = new JCheckBox("Option2"); checkBox.setOpaque(true);
In this example, a JCheckBox component with the label "Option2" is created and the setOpaque method is called with a value of true to make the checkbox opaque.
The setOpaque method is defined in the javax.swing.JComponent class, which is part of the javax.swing package library.
