since its introduction in java 8, the stream api has become a staple of java development. the basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use. but these can also be overused and fall into some common pitfalls. to get a better ...
There are some details to worry about with the use of super: It must always be the first action taken in a constructor definition. You cannot use it later in the definition of a constructor. In fact, if you do not include a call to the base-class constructor, then Java will automatical...
