Hello stachOverflow社区！这是我的第一篇文章，因此，如果我的文章样式不正确和/或我无法在此页面上讨论我发布的内容，请与我联系。
我的Java程序是Scrabble游戏的修改版本。这是我的游戏的运作方式：
我需要在我的代码中实现什么？
奖励积分，如果您也可以在这些事情上帮助我：
目前，我的游戏中有空白字母，提供程序用户决定制作的字母的磅值。相反，我希望任何空白图块都代表0分的得分，但是我不能仅仅在我的letterValue方法中添加一个case以在字符等于（_）时返回0，因为我必须告诉程序进行替换他们想要让空白图块代表的带有字母的空白图块。
目前，如果我的用户要收到多个空白图块，则我的程序会将给定的所有空白图块更改为只希望的一个字母。我想让我的用户能够让一个图块代表一个字母，而另一个图块代表他们选择的另一个字母。
这是我的Java游戏的当前代码：

Date: 10/23/2019
Programmer(s): Jaryn D. Giampaoli
Program: ScrabbleWordChampion
Version: 5.0
Purpose: This game will give the user 7 random letters. Then the user will be asked
to type in a word using those 7 letters and the game will then check if the word is
a playable word by looking it up in the official Scrabble word list using binary search.
If it is a real word the user is awarded points based on the values of the letters within
their given word.
*/
//ALGORITHM
/* Read in a file of words into an array of Strings
* Randomly pick 7 letters from alphabet (at least one vowel)
* Tell the player the 7 letters that were picked, and ask them for a word
* Input the word and then verify if it is a word (utilize Binary Search) and that it contains only letters they were given
* If it is a word, give points to the player based on the values of each letter utilized.

您想一遍又一遍地做任何事情，包括无效的输入，请使用while循环。 boolean inGamePlay = true; while（inGamePlay）{//提供并显示新的图块，并带有内部while循环要求生成单词，然后对其进行验证，计算点是否有效或再次询问是否无效，如果用户输入“退出”然后退出然后将isGamePlay设置为false，依此类推...}
