Create files with similar names using Java without overwriting existing file

Question

I was wondering if it is possible to create multiple files with similar names, without overwriting the current file.

for example: if I have a file: xyz.txt next time when i create it should be : xyz(1).txt

try {
  File makefile = new File("output.txt");
  FileWriter fwrite = new FileWriter(makefile);
  fwrite.write("example file");
  fwrite.flush();
  fwrite.close();
} catch (IOException e) {
  e.printStackTrace();
}

so if I re-run this program my current file should not be overwritten. I have already tried and if condition with a flag variable to add number as prefix to the file name.

I want to know if there are any Java commands to avoid overwriting an existing file.

Answer 1

Not in java as already indicated by @Greg Kopff. But you can work around something like this:

  int count = 0;

  public void createFile(String name) throws IOException
  {
    File f;
    f = new File(name);
    if (!f.exists())
    {
      f.createNewFile();
    }
    else
    {
      count++;
      createFile(name + (count));
    }
  }

i want to know if there are any native java commands to stop overwriting [and append a numeral to the filename]

Not in the core Java libraries, no.
