问题 I have an enum defined in Scala class as follows // define compression types as enumerator object CompressionType extends Enumeration { type CompressionType = Value val None, Gzip, Snappy, Lz4, Zstd = Value } and I have class that I want to Serialize in JSON case class ProducerConfig(batchNumMessages : Int, lingerMs : Int, messageSize : Int, topic: String, compressionType: CompressionType.Value ) That class includes the Enum object. It seems that using GSON to serialize causes StackOverflow

问题 I am trying to compile a program that was provided to me. The program tests the run time of the algorithm quicksort when provided different values. I need to increase the size of the stack to run really large numbers. I read to use the following command: g++ -Wl,--stack,<size> where size is the number to increase the stack. However, this isn't working for me. In command prompt when I typed exactly the following: g++ -Wl,--stack,1000000000 and then hit enter, I get the following message: C:

问题 thanks in advance for any clarity you can offer. In an Excel Workbook with many modules and worksheets, at the bottom of the VBA code for SHEET2, there is this Subroutine: Private Sub Worksheet_Change(ByVal Target As Range) Dim TargetCells As Range Set TargetCells = Range("B1000:B1029") If Not Application.Intersect(TargetCells, Range(Target.Address)) Is Nothing Then Call SpecificSubRoutine End If End Sub My understanding of this code is that it watches the entire sheet for ANY changes. If

问题 I need to find the longest way (from bigger to lower) between numbers in array. I've tried to write recursive function and got java.lang.StackOverflowError , but for the lack of knowledge I didn't understand why this happened. Firstly, I've initialize array and fill it with random numbers: public long[] singleMap = new long[20]; for (int i = 0; i < 20; i++) { singleMap[i] = (short) random.nextInt(30); } Then, I try to find the longest route of counting down numbers (e.g. { 1, 4, 6, 20, 19, 16

问题 With the StackOverflowException are the conditions to be thrown hardcoded or dependent on the machine the code is running on? I am almost certain the latter but have failed in my searches and don't ask enough questions here. 回答1: From the documentation: ... is thrown when the execution stack overflows because it contains too many nested method calls. Since the size of the stack is architecture-dependent and can even be overridden on a machine, yes, this value is not hard-coded, though it is

问题 I just spent some time chasing down a bug that boiled down to the following. Code was erroneously overwriting the stack, and I think it wrote over the return address of the function call. Following the return, the program would crash and stack would be corrupted. Running the program in valgrind would return an error such as: vex x86->IR: unhandled instruction bytes: 0xEA 0x3 0x0 0x0 ==9222== valgrind: Unrecognised instruction at address 0x4e925a8. I figure this is because the return jumped to
