[java 8 lambdas and streams and streams

在利用Java 8 lambdas and stream时处理检查的异常。但是，与期望相反：

的限制异常：

A Potential Solution (Missed Opportunity):

A more appropriate design could have involved a type parameter that explicitly denotes the exception types that the function or stream handles.这样的机制将有助于沿流管线的检查异常的无缝传递：接口函数 { //明确声明潜在例外。 r应用（t t）抛出e; } 接口流 { //异常的通行类型参数。 流映射（函数 mapper）抛出e; }

With this approach, the compiler could accurately infer the exception types that the stream operations would handle, allowing for transparent exception handling.

Conclusion:

The absence of proper checked exception handling in Java 8 lambdas and streams remains an unresolved issue.尽管有可靠的方法，但它们要么需要运行时异常转换，要么需要在流中繁琐的尝试/捕获块。缺乏全面的解决方案突出了当前功能接口设计在处理检查的例外的局限性。
