Jtable in swing sets the foreground color and background color of the selected row in the table

Jtable itself has no way to directly set the foreground color and background color of the selected row, but we can implement the functions we need by writing tablecellrenderer. This interface defines the methods required to become any object in the jtable cell Renderer.

By Rewriting
Gettablecellrenderercomponent (jtable table, object value, Boolean isselected, Boolean hasfocus, int row, int column)

Returns the component used to draw cells.
Table-The jtable to be drawn by the Renderer; it can be null.
Value-the value of the cell to be rendered. This value is interpreted and drawn by the specific Renderer. For example, if the value is a string "true", it can be rendered as a string or as a selected check box. Null is a valid value.

Isselected-if you use the highlighted display of the selected style to present the cell, the value is true; otherwise, the value is false.
Hasfocus-if it is true, the cell is properly rendered. For example, place a special border on a cell. If you can edit the cell, it is displayed in color to indicate that the cell is being edited.
Row-row index of the cell to be drawn. When the header is drawn, the row value is-1
Column-column index of the cell to be drawn
