java中未经检查和运行时异常[重复]-Uncheckedandruntimeexceptionsinjava[duplicate]

5  

All runtime exceptions (e.g. NullPointerException) are unchecked exceptions.

所有运行时异常（例如NullPointerException）都是未经检查的异常。

Since errors (e.g. StackOverflowError) are also unchecked exceptions, not all unchecked exceptions are runtime exceptions.

由于错误（例如StackOverflowError）也是未经检查的异常，因此并非所有未经检查的异常都是运行时异常。

The Java Language Specifications define an unchecked exception: "The unchecked exception classes are the run-time exception classes and the error classes."

Java语言规范定义了一个未经检查的异常：“未经检查的异常类是运行时异常类和错误类。”
