• FlowLayout when used arranges swing components from left to right until there's no more space available. Then it begins a new row below it and moves from left to right again. Each component in a FlowLayout gets as much space as it needs and no more.
• BorderLayout places swing components in the North, South, East, West and center of a container. You can add horizontal and vertical gaps between the areas.
• GridLayout is a layout manager that lays out a container's components in a rectangular grid. The container is divided into equal-sized rectangles, and one component is placed in each rectangle.
• GridBagLayout is a layout manager that lays out a container's components in a grid of cells with each component occupying one or more cells, called its display area. The display area aligns components vertically and horizontally, without requiring that the components be of the same size.
