Question

我必须检查我在数组中给出的所有测试用例，但我没有得到完美答案。请帮助我解决这个问题。创建一个包含以下内容的PowerBall类：

大小为6的int数组的字段。
使用6个随机值（0-9）初始化此数组的构造函数。
一种名为checkMatch的方法，它将int数组作为参数，并返回与类int数组匹配的数量。要匹配，相同的数字必须位于相同的位置。

写一个主要课程，要求用户输入6个数字作为他们的彩票并将其存储在一个数组中。然后创建一个PowerBall对象，并将用户的票证提供给checkMatch方法。然后根据返回值计算出赢得的金额。

奖金的确定如下：

如果0个匹配，则没有奖金
如果1个匹配，则赢取$ 4
如果2个数字匹配，则赢取$ 7
如果3个数字匹配，则赢取$ 100
如果4个数字匹配，则赢取$ 10,000
如果5个数字匹配，则赢取$ 100万
如果所有6个号码都匹配，则赢得4.5亿美元的大奖

输出用户的彩票，强力球数量，匹配数量以及赢得的金额。

这是计算比赛次数的好方法。

 public int checkMatch(int [] userTicket)
        {

            int currIndex = 0; 
            int amountNumsMatching = 0; 

            if(userTicket.length == this.ticketNumber.length)
            {
                for (currIndex = 0; currIndex < this.ticketNumber.length; currIndex++)
                {
                    if(this.ticketNumber[currIndex] == userTicket[currIndex])
                    {
                        amountNumsMatching++; 
                    }

                }
            }

            return amountNumsMatching; 

        }
