Layout managers are software components used in widget toolkits which have the ability to lay out graphical control elements by their relative positions without using distance units. It is often more natural to define component layouts in this manner than to define their position in pixels or common distance units, so a number of popular widget toolkits include this ability by default. Widget toolkits that provide this function can generally be classified into two groups:
Those where the layout behavior is coded in layout managers, that can be applied to any graphic container. This is the case in the Swing widget toolkit that is part of the Java API.

The FlowLayout layout manager arranges components in a directional flow, much like lines of text in a paragraph. It arranges components horizontally until no more components fit on the same line, then it places them on another line. Other layout managers are GridLayout managers which arrange the components in grid form and BorderLayout managers which also arranges the component in five parts of the frame, thus: south, north, west, east and center.
This code shows 5 buttons alongside each other on the same line:
