Hello, I'm trying to do a thing pretty much the same although more simple.
I'm trying to list all contents of a directory, then check if the directory has a directory inside it named according to the contents of the file readed. To summarize, I'm trying to repeatedly open files and compare them.
Here is the code I've written so far:
package archivos;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.io.File;
import java.util.StringTokenizer;
class ej18 extends Frame implements ActionListener
     private TextField tf;
     private Button b;
     private TextArea ta1,ta2,ta3,ta4;
     private Label la;
     ej18()
          setLayout(new FlowLayout());
          setSize(200,200);
          setVisible(true);
          la = new Label("Escribe el nombre del directorio donde se encuentra patrones y patrones.txt:");
          tf = new TextField("",20);
          ta1 = new TextArea(15,40);
                ta2 = new TextArea(15,40);
                ta3 = new TextArea(15,40);
                ta4 = new TextArea(15,40);
                b = new Button("Comenzar");
          b.addActionListener(this);
          add(la);
          add(tf);
          add(b);
          add(ta1);
      add(ta2);
      add(ta3);
          add(ta4);
      pack();
     public void actionPerformed(ActionEvent e1)     
          String x,y;
          Button Boton;
          Boton = (Button)e1.getSource();
          int op=0;
          if(Boton==b)
               try
                 x=tf.getText();
               File patrones = new File(x);
               if(patrones.exists()&&patrones.isDirectory())
               {ta1.append("******\nDirectorio <patrones> existe\n");}
               else{ta1.append("Directorio <patrones> no existe\n");}
               String[] files1 = patrones.list();
               ta1.append( "Archivos:\n" );
               for( String file : files1 ){ta1.append( file + "\n");}
               File textfile = new File(x,"patrones.txt");
               if(textfile.exists()&&textfile.isFile())
               {{ta2.append("******\nArchivo <patrones.txt> existe\nContenido:\n");
                BufferedReader in = new BufferedReader(new FileReader(textfile));
                    String s="";
                         //tokeinzer
                   while ( s != null )
               ta2.append(s+"\n");
                    s = in.readLine();
                         String rs=s;
               String[] result = rs.split(",");
                         String r = result[result.length-1];
                         File textfile1 = new File(x,r);
               if(textfile1.exists()&&textfile1.isFile())
                         {ta3.append("*****\nArchivo <"+r+"> existe\nContenido\n");
               StringTokenizer st = new StringTokenizer(r,".");
               String rr=st.nextToken();
                         File textdir = new File(x,rr);
               if(textdir.exists()&&textdir.isDirectory())
                         {ta4.append("*****\nEl directorio <"+rr+"> existe\n");
               String[] files2 = textdir.list();
               ta4.append( "Archivos:\n" );
               for( String file : files2 ){ta4.append( file + "\n");}
                         else{ta4.append("*****\nEl directorio <"+rr+"> no existe\n");}
               BufferedReader in1 = new BufferedReader(new FileReader(textfile1));
                         String ss="";
                   while ( ss != null )
                      ta3.append(ss+"\n");
                      ss = in1.readLine();
                         else{ta3.append("*****\nArchivo <"+r+">  no existe\n");}
                         //!tokenizer
                    in.close();}}
               else{{ta2.append("Archivo <patrones.txt> no existe\n");}}
               catch (Exception e2)
                    System.err.println("File input error");
class Intanciador_ej18
     public static void main(String ar[])
          ej18 obj = new ej18();
