How to use a Hash before defining it in Ruby -


I have a Ruby script that has a very long hash with more than 300 organizations. The script looks like this: 

  #! / Usr / bin / env ruby ​​Array_A = [] myHash = {"x1" => "2", "x2" => "0", "x3" => "1",. . "X350" = & gt; "1"} myHash.keys.each do | Z | Array_A & lt; & Lt; "This key is" + z finally puts myHash.values.join ("|") Array_A.join ("|")   
 But since hash is too large, the purpose of reading I will put a hash at the end of the script and  puts each  loop and  command first, something like this:  
  array_a = [] myHash .keys.each do | Z | Array_A & lt; & Lt; "This key is" + z end myHash.values.join ("|") puts Array_A.join ("|") myHash = {"x1" => "2", "x2" => "0", "x3" => "1",. . "X 350" = & gt; "1"}   
 Is there any way to do this?   
 
 
 This is a little weird, but it is basically for data. The catch is that it is a file that contains the contents of the section after  __ END __ , so you have to go to a hash with that. So something like this:  
  array_a = [] myHash = eval DATA.read myHash.keys.each do | Z | Array_A & lt; & Lt; "This key is" + z finally puts myHash.values.join ("|") Array_A.join ("|") __END__ {"x1" => "2", "x2" => "0", "x3" => "1 one ?? | "X350" = & gt; "1"}

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...

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...
