    byte[] buffer = new byte[1024];

    while ((bytesRead = fin.read(buffer)) > 0) {
    fout.write(buffer, 0, bytesRead);
    }

    Just use something like this:
    public static void main(String args[]){
    Scanner input = new Scanner(System.in);
    System.out.println("Enter the destination file name");
    String dest = input.nextLine();
    System.out.println("Enter the source file name");
    String source = input.nextLine();
    if(copy(new File(dest), new File(source))){
    System.out.println("Successfully copied");
    }
    }
     
    public static boolean copy(File dest, File src){
    boolean copied = true;
    String copyText = "";
    BufferedWriter writer;
    if(!dest.exists() && !src.exists()){
    copied = false;
    }else{
    try{
    Scanner reader = new Scanner(src);
    while(reader.hasNextLine()){
    String line = reader.nextLine();
    if(line != null){
    copyText += copyText+"\n";
    }
    }
    }catch(Exception e){
     
    }
    try{
    writer = new BufferedWriter(new FileWriter(dest, true));
    writer.newLine();
    writer.write(copyText);
    }catch(Exception e){
     
    }finally{
    try{
    writer.flush();
    writer.close();
    }catch(Exception e){
     
    }
    }
    }
    }

    Something like that.
