Answer:

BorderLayout

Border Layout

BorderLayout.is a frequently used layout manager. The container it manages corresponds to a rectangle on the screen. That rectangle is divided up into five regions:

Each region may hold only one component, although that component may be a panel (and usually is). The panel may contain several components. The layout manager adjusts the size of the regions depending on what is in them. You don't have to put a component in each region. If a region has no component in it, it shrinks to a small area.

QUESTION 7:

Add the three panels, genderPanel, heightPanel, resultPanel, to the content pane.

// content pane
getContentPane().setLayout( new BorderLayout() );
getContentPane().add( genderPanel, BorderLayout. );
getContentPane().add( heightPanel, BorderLayout. );
getContentPane().add( resultPanel, BorderLayout. );
