String.substring() is a method, not a field, meaning you need to call str.substring() rather than simply str.substring. Further, the substring method takes parameters – you have to tell it the specific substring you want in the form of which indexes within the string. str.substring(0, 2) would print characters 0 and 1 (the upper bound is … Read more
This is because your compiler is not able to find the necessary packages and or libraries that are needed to resolve these imports. These packages must be included in your class path. For example all of the errors regarding org.apache.felix.scr.annotations.x can be resolved after downloading the latest .jar from https://mvnrepository.com/artifact/org.apache.felix/org.apache.felix.scr.annotations/1.11.0 Follow these steps to include … Read more
Try this one – CREATE FUNCTION dbo.udf_getCountCallOnDate ( @DateFrom DATETIME , @DateTo DATETIME ) RETURNS INT AS BEGIN RETURN ( SELECT SUM(CallsTakenOnDate) FROM dbo.PhoneCalls WHERE DateOfWork BETWEEN @DateFrom AND @DateTo ) END SELECT DateOfWork = CONVERT(VARCHAR(10), t.DateOfWork, 111) , [Count] = SUM(t.CallsTakenOnDate) FROM dbo.PhoneCalls t WHERE DateOfWork BETWEEN @DateFrom AND @DateTo ORDER BY t.DateOfWork 0 … Read more
It seems pretty logical to me: You have a first event handling method execution in the EDT which gets the firmware version and then gets the port reader. Getting the firmware version causes an event to be received, in a different thread (and thus in parallel to the execution of portsMethod() in the EDT). The … Read more
Boxing is considered slow because it implies the allocation of an object. In your case that object is short lived (will probably not survive Gen0), which makes it cheap. A recent microbenchmark I did put the cost of generating a short lived object at about ~15 CPU cycles. Cost might be a bit higher in … Read more
This is a question of opinion, so I’m not sure this is the best forum. However you have several options, including some that could be completely free. Rails and PHP as you have mentioned can be used to create a backend using mysql as the data layer. If you are new to both of those … Read more
A MS SQL Server database, by default, only has a single schema (dbo). You can add schemas to group things for either security or organizational purposes. In your case, the schema apbd was created and Student was created on that schema not the dbo schema. So, to reference that table, you need to use [apbd].[Student]. … Read more
Of your three examples, _foo1 and _foo3 are both instance variables (ivars) and are functionally equivalent (though there are some old compilers that that didn’t permit ivars in the @implementation). I’ve seen people argue passionately for the @implementation pattern, your _foo3 example. See the somewhat dated Where to put iVars in “modern” Objective-C? But I … Read more

I think there is confusion here! a confusion matrix is set(y_test) + set(y_pred). so if this comes to be 8. then the matrix will be 8 X 8. Now, if you have more labels you want to print even though it does not matter if it’s all zero. then while building the matrix , you … Read more

There is no generic means to steal cookie data. It requires either: a security vulnerability (typically an XSS one) in a site that you can exploit to read the data or for the connection to be insecure and for you to have access to the networks the requests and response pass through The Synchronizer Token … Read more
In this case, you can consider using the Microsoft Graph – Create Group First, ensure you have assigned the “Microsoft Graph” > “Read and write all groups” permission to app in Azure AD.
