Simulating a FileFilter

[Ash maker]

Hello,
I develop a class file, I begin with java and I want to simulate a filter with this function, but I stuck on how to return the collection of File
Here is my code

Public File[] list(String monFiltre){
        File[] tbfh;
        for(File f: myFile.listFiles()){
        if(f.getName().endsWith(monFiltre)){
            tbfh = f;
        }
        }
        return tbfh;
    }

Any help on this will be appreciated, thanks for the help.

Hello,
I think tbfh is an array of File while f is a File, you can not do, they are of different type. Prefer to use ArrayList, like this:
Here is the code showing this

ArrayList fl = <File> new ArrayList <File>();
for(File f: mfile.listFiles()){
        if(f.getName().endsWith(mnfl)){
            fl.add(f);
        }
        }
        return fl.toArray(new File[fl.size()]);

Hello,
I am new to java, just a try and nothing serious, I think your class should look something like this

import java.io. *;
import javax.swing.JOptionPane;
 
 
Public class File {
    private File mfl;

Public File[] list(String mnfl){

Try this type of a syntax in your code.

Hello,
I advice you to add a second parameter to your method 'list' type File to what is more easily reusable. This would:

Public File[] list(mnfl String, File mnfl){
ArrayList fl = <File> new ArrayList <File>();
for(File f: mnfl.listFiles()){
        if(f.getName().endsWith(monFiltre)){
            fl.add(f);
        }
        }
        return fl.toArray(new File[fl.size()]);
}

But if you do not plan to use this method outside of your class, then forget what I just said. The code works?

Hello,
A better idea is of having inheritance. Your class MyFile everything looks like a utility class which you will serve in bcp class. So I think you said the static, makes you a sales person for use in your class. Instead of using inheritance, it would be possible to use the decorator pattern bcp more elegant and does the job. Java can also invoke the power of regex you can use instead of str.endsWith (mnfl). Your filter is a regex and the method is gaining in power and time. Hope the information will help you.

Hello,
Alternatively you can try the following code

..
Public void Copy(String fileName)throws IOException{
   FileInputStream f =new FileInputStream(this.fileName);
   FileOutputStream fout =new FileOutputStream(fileName);
   FileChannel flch = f.getChannel();
   FileChannel chflout = fout.getChannel();
   long sz = Chin.sz();
   Chin.transferTo(0, sz, chflout);
   Chin.close();
   chflout.close();
   did.close();
   fout.close();
}
