Add An Item In A Seq In Scala
Answer : Two things. When you use :+ , the operation is left associative , meaning the element you're calling the method on should be on the left hand side. Now, Seq (as used in your example) refers to immutable.Seq . When you append or prepend an element, it returns a new sequence containing the extra element, it doesn't add it to the existing sequence. val newSeq = customerList :+ CustomerDetail("1", "Active", "Shougat") But appending an element means traversing the entire list in order to add an item, consider prepending: val newSeq = CustomerDetail("1", "Active", "Shougat") +: customerList A simplified example: scala> val original = Seq(1,2,3,4) original: Seq[Int] = List(1, 2, 3, 4) scala> val newSeq = 0 +: original newSeq: Seq[Int] = List(0, 1, 2, 3, 4) It might be worth pointing out that while the Seq append item operator, :+ , is left associative , the prepend operator, +: , is right as
Bootstrap 4 File Input
Answer : Updated 2021 Bootstrap 5 Custom file input no longer exists so to change Choose file... you'd need to use JS or some CSS like this. Bootstrap 4.4 Displaying the selected filename can also be done with plain JavaScript. Here's an example that assumes the standard custom-file-input with label that is the next sibling element to the input... document.querySelector('.custom-file-input').addEventListener('change',function(e){ var fileName = document.getElementById("myInput").files[0].name; var nextSibling = e.target.nextElementSibling nextSibling.innerText = fileName }) https://codeply.com/p/LtpNZllird Bootstrap 4.1+ Now in Bootstrap 4.1 the "Choose file..." placeholder text is set in the custom-file-label : <div class="custom-file" id="customFile" lang="es"> <input type="file" class="custom-file-input" id="exampleInputFile" aria-describedby=&q
Are Triangles The Strongest Shape?
Answer : Here's one part of it. As far as polygons go, a triangle is the only one that is defined by its side lengths. If you have a triangle of sides 5,6, and 7, there is only one shape it can take. The same cannot be said of other polygons. Imagine a square. It can be squished into a diamond with the same side lengths. There is SSS congruence for triangles, but no analogous congruence for other polygons. That's what diagonal bracing does in physical structures. Creates triangles. As you asked about the strength of a triangular shape then let me introduce to the triangular chain consisting of three rigid links or bars connected to each other by pin joints(allowing rotation between two joined links) . The degree of freedom (n) of a plane chain is given by the Grasshoff's law as n = 3 ( l − 1 ) − 2 j − h n=3(l-1)-2j-h n = 3 ( l − 1 ) − 2 j − h for a triangular chain we have l = no. of links = 3 l=\text{no. of links}=3 l = no. of links = 3 j = no. of bin

Add Default Value Of Datetime Field In SQL Server To A Timestamp
Answer : For modifying an existing column in an existing table: ALTER TABLE YourTable ADD CONSTRAINT DF_YourTable DEFAULT GETDATE() FOR YourColumn This can also be done through the SSMS GUI. Put your table in design view (Right click on table in object explorer-> Design ) Add a column to the table (or click on the column you want to update if it already exists) In Column Properties, enter (getdate()) in Default Value or Binding field as pictured below In that table in SQL Server, specify the default value of that column to be CURRENT_TIMESTAMP . The datatype of that column may be datetime or datetime2 . e.g. Create Table Student ( Name varchar(50), DateOfAddmission datetime default CURRENT_TIMESTAMP );

Break / Stop Execution In UML Sequence Diagram Mid-way Inside Alt / Opt
Answer : There are three options for this situation. Each of them I illustrate with a diagram showing how the respective combined fragment should be used. The actual behaviour is hidden with interaction references (normalFlow for a flow that should normally be executed and breakFlow for any flow that should happen in case of a required break). The first solution is the most convenient one - it exactly covers your case and you can also use the positive version of a break guard. However each of them provide you a valid possibility. Break combined fragment When a break combined fragment is met and its guard condition is true, only this fragment is still executed and then the execution of the interaction (flow) stops. If the condition is not met, the combined fragment is omitted and the normal flow continues. This is exactly the case you describe. In this case you would put the messages that shouldn't be executed in case of a break condition after the break combined fragment
