Two JInternalFrames inside a JDesktopPane
I had developed 2 menu items under a menu
MENU is DISPLAY
MENUITEM-1 is DISPLAY_TABLE
MENUITEM-2 is DISPLAY_SUMMARY
When I click DISPLAY_TABLE; table is read from a file
and parsed and displayed in JTable perfectly.
But when I click DISPLAY_SUMMARY, I am not getting anything.
I feel that I had added everything correctly.
I dont know what is the mistake here in this code.
Anyone please help me. My code is here.
