java - Comparing a text from a EditText with an array of string characters -


I am trying to compare text taken from the EditText box - Edittext.getText () with an array of pre string characters. ToString () 

  string [] alphabets = {"a", "b", ........ "z"}   
 I want to compare each letter with the string of text with the edit characters so that I can change the position of one character with another (text taken from the edit text) I can do? Or is there any other better way to do this? Just want to know how to compare each step of the string.  
  edittext.getText (). ToString ()  with an array of  string [] alphabets = {"A", "b", ........ "z"} .  
     
  1.  What is a better way to parse  string  for a  int  such that I get the text from an edit text box And I want to consider it an integer, how can I do this?   
     I am asking this question because I have to implement the encryption algorithm  modular arithmetic / mathematics  thanks   
     
     
     -    string editing value = edittext.getText (). ToString (); Integer interval = integer. Parsient (editview);

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.

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...
