InputMismatchException 在扫描程序中从 txt 文件中获取数据

问：

我正在尝试从 txt 文件中读取游戏的高分并将它们放入数组中，以便程序的另一部分可以检测到高分。早些时候，我将所有内容都声明为 Int，它工作正常，但我想要更高的精度，所以我决定让所有东西都尽可能长地计算小数。但是，当我从int更改为long时，出现了此错误。我一直在寻找解决方案，但没有一个适合我。谁能看一下？

作为参考，txt 文件包含

95,0
1,0
1,0

错误“线程”AWT-EventQueue-0“java.util.InputMismatchException中的异常出现在第 74 行，即

top3[i] = scanner.nextLong();

尽管 Top3 被声明为长。
