How to get characters to a string in Java? -


I have a text file that has hexadecimal values ​​like "Captured Network Packets Headers" ... 

  FC-C8-97-62-88-5F-74-DE-2B-C8-C7-E5-08-00-45-00-00-28-4E-C4 -40-00 -80-06-BD-65-C0-A8-01-03-AD-C2-7F-38-C9-96-01-BB-F8-01-7F-5F-B6-8A-15 -22-50 -10-40-42-72-8C-00-00.   
 I need to convert them into decimal values ​​... I was very few here ..  
  InputStream input = new FileInputStream ("data. Txt "); OutputStream Output = New FileOutputStream ("converteddata.txt"); Int data = input Reed (); While (data! = -1) {char ch = (four) data; Output.write (ch); Data = input.read (); } Input.close (); Output.close ();   
 Now, my problem is ... How to get each hexadecimal string in which there will be '2' characters? (Such as "edi" or 5f etc.) to convert them into successive values.  
 I know that C ++ is not a function "fgetc ()" ..? I need a similar solution. Can anyone recommend a good solution ..? (Sorry, I'm starting for Java, but C ++ knows very well) Thanks in advance.   
 
 
 Here is a sample code. Please customize for real-time use.  
  Public static zero main (string [] args throws IOException {output output output = new FileOutputStream ("converteddata.txt"); Bufferbrd br = new buffed reader (new filereader (new file ("data .ttt")); String r = null; (String = string: str) {long l = long parcelong (string.trim () (= (r = br.readline ())! = Null {strings [] str = r.split ("-"); , 16); output.write (String.valueOf (L) .getBytes ()); output.write ("\ n" .getBytes ());}} Br.close (); output.close ();} < / Code>

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...
