Use GridBagLayout to control the height and width of rows and columns

Gridwidth Specifies the number of cells in a row of a specified component display area. Default value 1, Level one grid

gridheight Specifies the number of cells in a column in the component display area. Default value 1, one grid vertically

weightx Specifies how additional horizontal space is distributed. The default value is 0, and the extra horizontal space is not allocated.
Weighty Specifies how additional vertical space is distributed. The default value is 0, and additional vertical space is not allocated.

After stretching the effect is as follows
