GridBagLayout is a flexible layout manager that allows components to span multiple rows and columns and have varying sizes. It uses GridBagConstraints objects to control the placement of each component, specifying attributes like grid width, grid height, and gridx/gridy coordinates. The maximum number of rows and columns in a GridBagLayout is 512.
