Hello, my program is about connectFour game. I need help with resolving the logic for this problem. I appreciate your help very much.
**Client:**
package FourPack;
import javax.swing.*;
/* Algorithm
Level 0:
Continue until the user wishes to quit
Prompt the user to select whether they will be playing with another player or against the computer
Prompt the user to select whether they will be player 1(yellow) or player 2(red)
Player 1 selects which column they will be placing their token in
Place the token at the top of the chosen column
Repeat the same process for player 2
If either player attempts to place the token in a full column, output an error message
Inform each player of how many tokens each has remaining
If either player gets four of their tokens in consecutive diagonal, horizontal, or vertical order before the other, they win
