c# - Sorting a dictionary by keys in the order in an Arraylist -


I was asked the following question in an interview. I can sort a dictionary from the key, in order that any array is in the list.

For example, I have a dictionary such as 

  dictionary ; String, string & gt; StringDict = New Dictionary & lt; String, string & gt; (); StringDict.Add ("1", "One"); StringDict.Add ("7", "Seven"); StringDict.Add ("6", "Six"); StringDict.Add ("2", "Two"); StringDict.Add ("3", "Three"); StringDict.Add ("5", "Five"); StringDict.Add ("4", "Four");   
 and an array list is as follows  
  array list stringArList = new ArrayList (); stringArList.Add ("1"); StringArList.Add ("2"); stringArList.Add ("3"); StringArList.Add ("5"); stringArList.Add ("6"); StringArList.Add ("7"); stringArList.Add ("4");   
 How can I sort this array in the order in order?   
 
 
 Well, you can not click a dictionary, but you can   Remove the key-value pair as a list and sort the  those  types:    IEnumerable & lt; keyValuePair & lt; String, string & gt; & Gt; Pairs = string dict ordbari (kvp = & gt; string ARLIST.indexoff (kvp.ca));   
 But there is no way to translate "objects" in any particular order.  
 You can create a  sorted option  and a  IcpParator < String & gt;   
  var d = new ordered order & lt; String, string & gt; (String Dict, New Position Compaiper (String Elite));   
 In the form of the implementation    
  Public class status compiler: ICMPier & lt; String & gt; {Private Arrival Keys {Get; Set;} Public Position Comparator (Ariallist Keys) {keys = keys; } Public Intel (String S1, String S2) (Return Keys Indexoff (S1)) Compare. (Compare key (indexoff (s2));}}

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

java - JPA TypedQuery: Parameter value element did not match expected type -

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
