To force a layout manager to re-layout the components in a container, you can invoke the container method called
a. validate()
b. repaint()
c. layout()
d. update();

repaint() is for painting purposes only (partial exposure, application painting efforts etc..)
validate() is the rite answer
Please refer the JDK API docs for further explanations
