ruby on rails - How to add up the number representations of the objects of the hashes in an array of hashes? -


हैश की एक सरणी 

  [{color: "red", आकार: " बड़े "}, {रंग:" नीला ", आकार:" छोटा "}, {रंग: बैंगनी, आकार:" मध्यम "}, {रंग:" गुलाबी ", आकार:" छोटा "}]   
 इसके अलावा एक और हैश:  
  {छोटा: 1, मध्यम: 2, बड़ा: 3, x_large: 4}   
 कैसे होगा सभी आकारों को उनके संबंधित नंबरों से बदल दें और उन संख्याओं को जोड़ दें?  
 समस्या को ऐसे आकारों की जगहों से बदलकर मैन्युअल रूप से हल किया जा सकता है:  
  [{रंग : "लाल", आकार: 3}, {रंग: "नीला", आकार: 1}, {रंग: बैंगनी, आकार: 2}, {रंग: "गुलाबी", आकार: 1}]   
 फिर उन आकारों को जोड़कर, आकारों का प्रतिनिधित्व करना होगा आउटपुट: 7   
 
 
 फिर से बदलना अपनी पहली सरणी, दूसरे सरणी से corrospoding आकार के साथ : आकार  की जगह:  
  arr = [{color: "red", आकार: "बड़ा"}, {रंग: "नीला", आकार: "छोटा"}, {रंग: "बैंगनी", आकार: "मध्यम"}, {रंग: "गुलाबी", आकार: "छोटा"}] आकार = {छोटा: 1, मध्यम: 2, बड़ा: 3, x_large: 4} arr.each do | x | X [: size] = आकार [x [: आकार] .to_sym] end

How can I add a seperate action listener to all 14 of my buttons at once that can determine player turn?(java) -

I have a big code, for a game I'm calling Tommy's Kumamak. I know that this is not beautiful, but I am very naive and for some reasons I know from using arrays, anyway, my problem is that I can not add a variable outside the listener and within the action listener I can modify the variable (pTurn ++) from How can I go about adding a count to that variable from inside the action listener? 1 error was found: file: c: \ user \ public \ togiz_kumalak.java [line: 130] error: local variables pTurn is accessed from within internal class; Need to be declared final int pTurn = 0; Button1.addActionListener {new zero-action action (action event e) {pTurn ++; if (pTurn% 2 == 0) {display.append ("\ n Player 2 cup 1");} If ( PTurn% 2! = 0) {display.append ("\ nPlayer 1Cup 1")}}); In that case, move the contents of the functionalities into orbit and then call the action For example, display the method from: Private Zero Button Press {pTurn ++; If (pTurn% 2...
