Swift closure loop reference and swift loop reference When a closure is used, the class itself holds self, and then accesses the attributes of self or self in the closure, which will lead to nausea of circular reference. The solution provided by swift is to define the capture list in the closure, and the capture list is how the closure wants to reference the captured variables. For example, the following d

Summary of Java list loop and map loop Do a list and map of the summary, there is no technical content, all the review of the API. The test environment is under JUNIT4, and it is the same without writing a main method yourself. First, there are three loops of the list: @Test public void Forlisttest () { list Then there are four loops of map: @Test public void Formaptest ()
