I need to create specific number of rows and columns but I have no idea how.

can you help me with this method?

package C4; /kok k Represents the state of a Connect Four board on which multiple games can be played. The board consists of a rectangular grid of squares in which playing pieces can be placed. Squares are identified by their zero-based row and column numbers, where rows are numbered starting with the bottom row, and columns are numbered by starting from the leftmost column. Multiple games can be played on a single board. Whenever a new game begins, the board is empty. There are two first in the second game, and so on in alternating fashion. A C4Board also keeps track of the outcomes of the games that have been played on it. It tracks the number of wins by * players, identified by the constants P1 (Player 1) and P2 (Player 2). P1 moves first in the first game, P2 moves * P1, the number of wins by P2, and the number of ties. It does not track games that were abandoned before being * completed public class C4Board The number used to indicate Player 1/ public static final int PI = 1; /The number used to indicate Player 2/ public static final int P22; The number used to indicate a tie public static final int TIE = 3; * Creates a C4Board with the specified number of rows and columns. There should be no pieces on the board and it * should be player 1's turn to move. However, if either rows or sgls is less than four, throws an IllegalArgumentException. public C4Board (int rows, int cols) package C4; /kok k Represents the state of a Connect Four board on which multiple games can be played.
