尝试将一个小的.txt文件加载到mysql中,但是除了null和\n之外,我的所有数据都显示在一个字段中.

这是数据布局:

Fluffy,Harold,cat,f,1993-02-04,null \N
Claws,Gwen,cat,m,1994-03-17,null \N
Buffy,Harold,dog,f,1989-05-13,null  \N
Fang,Benny,dog,m,1990-08-27,null  \N
Bowser,Diane,dog,m,1995-08-31,1998-07-29 \n
Chirpy,Gwen,bird,f,1998-09-11,null  \N
Whistler,Gwen,bird,null,1997-12-09,null  \N
Slim,Benny,snake,m,1996-04-29,null  \N

我使用的命令是:LOAD DATA LOCAL INFILE"c://petdata.txt" INTO TABLE pet; 这似乎正在工作,因为数据进入表但格式错误.

这是我的输出

mysql> SELECT*FROM pet;
+----------------------+-------+---------+------+------------+-------+
| name                 | owner | species | sex  | birth      | death |
+----------------------+-------+---------+------+------------+-------+
| Bowser,Diane,dog,m,1 |       |         |      | 0000-00-00 | NULL  |
| Buffy,Harold,dog,f,1 |       |         |      | 0000-00-00 | NULL  |
| Chirpy,Gwen,bird,f,1 |       |         |      | 0000-00-00 | NULL  |
| Claws,Gwen,cat,m,199 |       | …

无法弄清楚为什么我的代码只在我需要一个字符串时返回一个Int,并且帮助会很棒.代码如下.我尝试将变量声明为String而没有运气.

我想要返回3个随机字符串:樱桃,葡萄,铃铛或x

import java.util.Scanner;
import java.util.Random;

public class slot {
    public static void main(String[] args)
    {
        String answer = "y";
        int cherry;
        int grape;
        int bell;
        int x;



        Random generator = new Random(); // random generator
        Scanner scan = new Scanner (System.in); // scanner class

        System.out.println("Would you like to play the slot machine?(y/n): ");
        answer = scan.nextLine();

        while(answer.equalsIgnoreCase("y"))
        {
             cherry = generator.nextInt(5); // generates a random number
            grape = generator.nextInt(5);
            bell = generator.nextInt(5);

            System.out.println("The three numbers of the slot machine …
