My JTable is already set up for selecting a single cell at a time. I would like to know what command to use to get the cell at (selectedRow, selectedColumn) to have focus, too, not just selection. I assume I should get the component of the cell and do .requestFocus()

There's no 'component of the cell'. Are you looking for editCellAt(...) ?

The way my program is so far, the program selects a single cell, but when the user starts typing something, what the user typed does not enter the cell. What I want is to have the program make the cell so that the border of the cell changes color and when the user types something, it enters the cell.
Basically what I want is, what happens when the user clicks a cell once, except that I want the program to do it so that the user does not have to.

This happens by default when you use the DefaultTableModel since by default all cells are editable. Post your SSCCE that demonstrates the problem.

is there something that triggers the posted code?

a JButton? if so, make the button not focusable

Thank you. I just added this line:

and it seems to work okay now. I get it now. Just request focus for the table, and whatever cell is selected will be ready to edit (if the cell is editable).

Read the API for requestFocus(), it's recommended that you use requestFocusInWindow() instead.
