使用拆分的麻烦

Question

我试图从文件中分割文本读取,当我这样做时,它将整行作为一个数组元素,我做错了,或者只是分裂不是我需要使用的.

public void readBoard(String file)throws FileNotFoundException
{
    File clboard = new File ("myBoard.csv");
    Scanner x = new Scanner(clboard);
    while(x.hasNext())
    {
        String c = x.nextLine();
        String [] myboard =c.split(",,");
        int p1= Integer.parseInt(myboard[1]);
        int p2= Integer.parseInt(myboard[2]); 
        if(myboard[0].equals("Chute"))
        {
            board[p1][p2]= new Chute();
        }
        else
        {
            board[p1][p2]= new Ladder();
        }
    }   
} 

这是我正在阅读的文件

您可以在split方法中使用双逗号,而不是使用单个逗号.

String [] myboard =c.split(",,");

上面的行应该是:

String [] myboard =c.split(",");
