【问题描述】：
我设法弄清楚如何为我的连接四程序打印数组，但我无法用我的代码更新电路板，我查看并运行它，代码理论上可以工作，但是数组不会占用新的输入
我尝试使用 for 循环运行它，但结果是错误的，我正在考虑将 drop 方法放入 print board 方法中，但我觉得这会导致错误
public class Connect4 {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// DON'T MODIFY THE MAIN METHOD UNLESS FOR DEBUGGING
//MAKE SURE YOU GET RID OF YOUR MODIFICATIONS HERE BEFORE
SUBMISSION
String[][] board = createEmptyBoard();
Scanner input = new Scanner(System.in);
boolean bl = true;
printPattern(board);
while(bl) {
int player1 = 1 , player2 = 2 , userInput;
System.out.println("Please drop a RED disk at the column between 0
and 6:");
userInput = input.nextInt();
dropDisk(board, userInput , player1);
printPattern(board);
System.out.println("Please drop a YELLOW disk at the column
between 0 and 6:");
userInput = input.nextInt();
dropDisk(board, userInput , player2);
printPattern(board);
String win = checkWinner(board);
/*
Write code to announce if there is winner and end the game
*/
}
}
public static String[][] createEmptyBoard() {
/* This method prints the first empty pattern for the game
DON'T MODIFY THIS METHOD
*/
String[][] f = new String[7][15];
for (int i =0;i<f.length;i++) {
for (int j =0;j<f[i].length;j++) {
if (j% 2 == 0) f[i][j] ="|";
else f[i][j] = " ";
if (i==6) f[i][j]= "-";
}
}
return f;
} // end of createEmptyBoard
public static void printPattern(String[][] brd) {
for (int i = 0; i < 7; i++){
System.out.println(brd[i][0] + brd[i][1]+ brd[i][2]+ brd[i][3]+
brd[i][4]+ brd[i][5]+ brd[i][6]+ brd[i][7]+ brd[i][8]+ brd[i][9]+
brd[i][10]+ brd[i][11]+ brd[i][12]+ brd[i][13]+ brd[i][14]);
}
} // end of printPattern
public static void dropDisk(String[][] brd, int position, int
player) {
if (player == 1){
brd[6][position] = "R";
if(brd[6][position] == "R"){
brd[6][position] = brd[6 - 1][position];
}
}
else if (player == 2){
brd[6][position] = "Y";
if(brd[6][position] == "Y"){
brd[6][position] = brd[6 - 1][position];
}
}
/*Write your code to drop the disk at the position the user entered
depending on which player*/
} // end of dropDisk
