What is the difference between GridLayout and GridBagLayout?
A GridLayout puts all the components in a rectangular grid and is divided into equal-sized rectangles and each component is placed inside a rectangle whereas GridBagLayout is a flexible layout manager that aligns the components vertically and horizontally without requiring that the components be of the same size.
What does the GridBagLayout class allow you?
A GridBagLayout places components in a grid of rows and columns, allowing specified components to span multiple rows or columns. Not all rows necessarily have the same height. Similarly, not all columns necessarily have the same width.
What is insets in GridBagLayout?
Controls padding between the component and the borders of its area. Insets insets. Controls padding between the component and neighboring components. To make a set of constraints for a component or components, create a new instance of GridBagConstraints and set these public variables to the appropriate values.
What is the use of GridBagLayout?
A GridBagLayout is a very flexible layout manager that allows us to position the components relative to one another using constraints. Each GridBagLayout uses a dynamic rectangular grid of cells with each component occupying one or more cells called its display area.
How does Java’s BorderLayout work?

What is GridBagLayout in Java?
Each GridBagLayout object manages a rectangular grid of cells, dynamic with each component occupying one or more cells, called its display area. GridBagLayout components are associated with the instance of GridBagConstraints. These constraints are used to define the component’s display area and their positions.
What is FlowLayout Java?

What is GridBagLayout manager?
