Answer:

Null layout manager enables UI components to be placed at specified coordinates (x and y values).

Explanation:

Null layout is generally used by developers while creating demo UI or prototypes since the component location can be precisely specified in terms of x,y coordinates. This is also called absolute positioning.

However null layout suffers from a number of problems due to which it is normally avoided in production scenarios:

  • Hardcoded coordinates and sizes are not portable across different environments ( different screen sizes,resolutions and font sizes).
  • Null layout does not support preferred sizes for components.  Component size cannot change with environment.
  • User interface with null layout does not readjust automatically when the top level container is resized.
