DRY up java (lambda functions?) -

-

I'm writing a program in Java that essentially tests a bunch of things ...

every call, I need to check for NullPointerExceptions , StackOverflow , IndexOutOfBounds , etc. ... < P> This is repeating me now Pattern in each of my ways: 

  try {doSomething (); } Hold (NullPointerExceptions npe) {// Some Impressions} Catch (Stack Overflow Soi) {// Some Impressions} Catch (IndexOutBoond IOB) {// Print something}   
 Since I I can call the  throw  exception to back to the main (because I'm actually doing the same thing) To run in requires the next test).  
 I want to write a Lambda tester that I can pass the function, but I can not find any way to do this with Java :(.  
 I 'like Want to do something:  
  Private zero testing (method m, e hopeful) {try (if (! M.run (.) Equals (expected value)) system.out.println ( "Failure Test:" + m.name () + ". The value was" + m.run () + "," + expected value ");} hold () {// see above}}    
 
 
 all Better than you can use an interface in Java:  
  interface doSomething  gt; & gt; {e doSomething ();} < / Code>  
 Your  test  method can look like this:  
  Private Zero Testing (DoSomething  I , E expected value) {try (if (m.doSomething (.) Equals (expected values) System.out.println ("FAILED test");} hold () {// handle exception}}   
  e  needs to be expanded >  & Gt;  Because you are equal to   test  inside .  
 This is called a SAM (single abstract method) interface. The use of SAM classes and interfaces to simulate lambdass is a common occurrence in Java. I have also called them "Sambadas".  
  Edit:  My solution is not required to modify the existing sections:  
  DoSomething foo = New DoSomething & lt; String & gt; () {Public string doSomething () {Return "Hello World"; }}; Test (af, "hello world");

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
