Help to add functions in the java code below, a card holder in the middle

of the four cards in the panel, so when you draw a card from the card pile

up to the right.$($please see added pic$)$ towards the center of the four cards in

the panel, the cards will click into the center of the four cards in the panel. If it's possible to exnted from the below code given, Not possible to send the whole code because Chegg does not take more characters$(5000).$ Please let me know if you need more of the program code, if it's possble to communicate over a task. Thanks! import java.awt.$*$;
