I used the following codes but i am unable to delete the file. Can anyone help?

    public static void main(final String[] args){
        final Thread a = new Thread();
        a.start();

        final String fileName = "default\\sample.txt";

        // A File object to represent the filename

        final File f = new File(fileName);

        // Make sure the file or directory exists and isn't write protected

        if(!f.exists()){
            throw new IllegalArgumentException(

            "Delete: no such file or directory: " + fileName);
        }

        if(!f.canWrite()){
            throw new IllegalArgumentException("Delete: write protected: "

            + fileName);
        }

        // If it is a directory, make sure it is empty

        if(f.isDirectory()){

            final String[] files = f.list();

            if(files.length > 0){
                throw new IllegalArgumentException(

                "Delete: directory not empty: " + fileName);

    }

}

Or is there any other way to delete a file using threads?

这就是您要寻找的.

This is what you are looking for.

public class Delete extends Thread {

    public static void main(String[] args) {

        Thread a = new Delete();

        a.start();

    }

    public void run() {
        // your implementation
    }
}
