Question

I want to create a file but the below code doesn’t create any file.

package InputOutput;

import java.io.*;

public class FinalProject{

    private File f;

    public File createFile() throws IOException{
        f = new File("E:\\Programming\\Class files\\practice\\src\\InputOutput\\helpSystem.txt");
        return f;
    }

    public static void main(String[] args) throws IOException{
        FinalProject fp = new FinalProject();
        fp.createFile();
    }
}

In Java File represents a path name to a file or a directory, not a writable file stream. If you need to create a file, call createNewFile on the File object:

try {
    f.createNewFile();
} catch (IOException ex) {
    // Cannot create new file
}
