Stabilizing the error with the best answers: pointer to incomplete class type is not allowed
The cause: This error happens perhaps due to an "incomplete class" is one declared but not defined. The solution: To solve this problem, you need to #include "wielrenner.h" in dokter.ccp, because #include "wielrenner.h" is required in dokter.ccp in order for it to be aware of the class's details.

Ways to resolve the error – multiple connections to a server or shared resource by the same user
The cause: I think this error happens because it's possible that the Windows Credential Manager is retaining network sharing credentials. Even if you delete the shared folder using net use * /del, there is still a connection on the server side. The solution: To get around this difficulty, you need mRead more
The cause: I think this error happens because it’s possible that the Windows Credential Manager is retaining network sharing credentials. Even if you delete the shared folder using
net use * /del
, there is still a connection on the server side.The solution: To get around this difficulty, you need map the drive in such a way that Windows thinks it’s a different share on a different server. Using DNS aliases or IP addresses is the simplest way to do this. If your first mapping utilizes an IP address, such as
See less\\IP\Share
with your current credential, you should use something which establish a new share with the new credentials like\\ServerName\Share password /user:Domain\Username

Amazing solutions for the java lang noclassdeffounderror could not initialize class error

The cause: I think this error occurs in here:
It appears that an uncaught exception occurred, which was propagated to the ClassLoader that was attempting to load the class. Either that or it happened when the
PropHolder.prop
static variable was created.The solution: You’ll need to figure out what exception the
See lessstatic
block is throwing. To debug it, wrap the entire block in atry/catch(Exception e)
and log the exception. That exception will have to be fixed. Typically, the exception will be logged, but it may be difficult to locate because it is logged during classloading, which can happen very early in the process.The complete guide to the invalidoperationexception: collection was modified; enumeration operation may not execute issue

Quick handling of the exception in thread “main” java.util.nosuchelementexception: no line found error
The cause: Various coding flaws will cause this exception message to appear. The most typical cause of this error is when programmers call nextLine() in the context of a Scanner and there is no next line to follow. The solution: The readLine() method's API documentation states the following: Throws:Read more
