-
FlowLayout: Arranges components in a single line (flow).- Fields: constants for alignment include LEFT, RIGHT, CENTER, LEADING, TRAILING.
- Constructors create flow layouts with various alignments and default gaps.
-
BorderLayout: Divides the container into five regions: NORTH, SOUTH, EAST, WEST, CENTER.- Each region contains a single component, serving as the default for frames and windows.
- Constructors enable creation of layouts with or without gaps.
GridLayout Class
