我通过阅读一些相关文本来了解两者之间的差异.但我很好奇为什么getCanonicalPath()抛出检查异常而getAbsolutePath()不抛出任何东西？
解决方法
But I am curIoUs that why
getCanonicalPath()throws checked exception whilegetAbsolutePath()does not throw any?
它说明为什么在the documentation for getCanonicalPath：
IOException– If an I/O error occurs,which is possible because the construction of the canonical pathname may require filesystem queries
