To convert an ArrayList containing Integer objects to a primitive int array in Java, you can use the toArray method and a casting operation.
, value, number); } catch (OverflowException) { Console.WriteLine("Unable to convert '0x{0}' to a 16-bit integer.", value); } 在执行二进制运算或数值转换时,开发人员始终有责任验证方法是否使用适当的数值表示形式来解释特定值。 如以下示例所示,可以先检索数值的符号,然后再将其转换为其十六进制...
