Opening dans Reading Files

Question

Hi i have a question
want to open 2 data files
and then i want to compare them by reading 4 bytes at the time
this is how i open the files
from one class i call a method from another class like this
file2Read = new File2Read(file1)
file2Read2 = new File2Read(file2)
in my File2Read class i have a method that opens a new file like this
file = new DataInputStream( new BufferedInputStream( new FileInputStream(file)));
my problem is when i try to compare de data i have the same output for 2 different files
when it should be different
Could somebody help me with that thank you

Answer 1

what do you mean by don't declare it static
and this is the code in my first class to open the files
public void openFirstFile(){
     try {
          firstFile = new File2Read(file);
     } catch (FileNotFoundException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
public void openSecondFile(){
     try {
          secondFile= new File2Read(file);
     } catch (FileNotFoundException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
}this is the code in my class file2Read
public file2Read(String file) throws FileNotFoundException {
     try {
          /* open the handler on the specified file */
          file2read = new DataInputStream(
                         new BufferedInputStream(
                         new FileInputStream(file)));
     } catch (FileNotFoundException e) {
          /* the path is not valid */
          throw e;
}any one knows what could be the problem in there
thank you
