如果当前 `Class` 并不存在，使用上述方法会抛出异常，如果你不确定 `Class` 是否存在，可以参考下面的解决方案。
> 示例如下
```kotlin
// 直接得到这个 Class
// 如果当前正处于 PackageParam 环境，那么你可以不需要考虑 ClassLoader
// 得不到时结果会为 null 但不会抛出异常
var instance = "com.demo.Test".toClassOrNull()
// 自定义 Class 所在的 ClassLoader
val customClassLoader: ClassLoader? = ... // 假设这个就是你的 ClassLoader
// 得不到时结果会为 null 但不会抛出异常
var instance = "com.demo.Test".toClassOrNull(customClassLoader)
```
我们还可以通过映射来得到一个存在的 `Class` 对象。
