The following Java program copies the stack trace to a string. StringerrorStr=ExceptionUtils.getStackTrace(newNullPointerException("Custom error"));System.out.println(errorStr); Program output. java.lang.NullPointerException:Custom erroratcom.howtodoinjava.demo.StringExample.main(StringExample.java:11...
which prints to STDERR. But when you want to write to a logger, or otherwise convert a stack trace to a string, the second approach works very well. Here’s the approach encapsulated in a Scala method:
HRESULT hr = CoInitialize(NULL); if(FAILED(hr)) { //This is what I want to store into a string. //"Failed to Initialize COM. Error code = 0x" << hex << hr << endl; string hexerrorcode = ?; CoUninitialize(); return 0; } I am not sure how to put it into string. Can a...
Generally, the performance differences are negligible for small-scale applications, but String.valueOf() and Boolean.toString() are typically more efficient for simple conversions.
