This is java!

I need PSEUDOCODE for the following source code:

//ReadFile.java

import java.io.*; //import java.util.Scanner; public class ReadFile{ public static void main(String[] args) throws IOException{ Validation cc = new Validation(); try{ BufferedReader in = new BufferedReader(new FileReader("cardNumbers.txt")); String s; while((s = in.readLine()) != null){ Validation.getValidation(s); if(Validation.getValidity()==true) Validation.getCardIssuer(s); Validation.checkValidity(); //} //else //Validation.checkValidity();

System.out.println(cc.getStr()); } in.close(); }catch(FileNotFoundException e){System.out.println("File not found");}

}//end of main }//end of class
