Exception in thread "main" java.lang.VerifyError: Bad type on operand stack

这个错误通常表示在运行时出现了类型错误，导致虚拟机无法正确执行代码。这通常是由于编译时和运行时使用了不同的类版本或库版本所导致的。你可以尝试以下步骤来解决这个问题：

1. 确认你的编译器和运行时环境的版本是否一致。
2. 检查你的代码中是否有类型转换错误或错误的参数类型。
3. 检查你的代码是否依赖于其他库，而这些库的版本与你的代码不兼容。
4. 尝试使用不同的编译器或运行时环境来编译和运行你的代码，看是否能够解决问题。

如果以上方法无法解决问题，你可以在搜索引擎上搜索这个错误信息，看看是否有其他人遇到了相同的问题，并尝试参考他们的解决方案。

TypeError: bad operand type for unary -: 'str'

This error occurs when you try to use the unary minus operator (-) on a string instead of a numerical value.

For example:

x = "hello"
y = -x

In this case, the variable x is a string, and the unary minus operator cannot be applied to it. To fix this error, make sure that you are only using the unary minus operator on numerical values, such as integers or floats.
