File reading problem

Posted: Dec 13, 2004 8:57 AM

Hello, I read some of the java docs, but examples-mainly- focus on .txt files, I am having difficulties to read from different files, like .pdf, or .xls, part of my program:


FileRead f = new FileRead();

 f.readFile(); 
}

      void readFile() { 

         DataInputStream dis = null; 

         String record = null;

         int count = 0; 
      try { 

           File f = new File("myfile.pdf"); 

           FileInputStream fis = new FileInputStream(f); 

      BufferedInputStream bis = new BufferedInputStream(fis); 
           dis = new DataInputStream(bis);

           while ( (record=dis.readLine()) != null ) { 

              count++; 

              System.out.println(recCount + ": " + record); 
           }

thanks for your help.

Hi

You can use following code:

import java.io.*;

public class TempClass {
public static void main(String[] args) {

TempClass f = new TempClass();

f.readFile();
}

public void readFile() {
try {
FileOutputStream fos = new FileOutputStream("myfile2.pdf");
FileInputStream fis = new FileInputStream("myfile.pdf");
int ch;
while ( (ch = fis.read()) != -1 ) {
fos.write(ch);
}
fos.close();
fis.close();
}
catch(Exception e){e.printStackTrace();}
}
}
